The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
Bone Marrow Cells
Bone Marrow Transplantation
Bone and Bones
The continuous turnover of BONE MATRIX and mineral that involves first an increase in BONE RESORPTION (osteoclastic activity) and later, reactive BONE FORMATION (osteoblastic activity). The process of bone remodeling takes place in the adult skeleton at discrete foci. The process ensures the mechanical integrity of the skeleton throughout life and plays an important role in calcium HOMEOSTASIS. An imbalance in the regulation of bone remodeling's two contrasting events, bone resorption and bone formation, results in many of the metabolic bone diseases, such as OSTEOPOROSIS.
Bone Marrow Neoplasms
The amount of mineral per square centimeter of BONE. This is the definition used in clinical practice. Actual bone density would be expressed in grams per milliliter. It is most frequently measured by X-RAY ABSORPTIOMETRY or TOMOGRAPHY, X RAY COMPUTED. Bone density is an important predictor for OSTEOPOROSIS.
Bone Marrow Purging
Techniques for the removal of subpopulations of cells (usually residual tumor cells) from the bone marrow ex vivo before it is infused. The purging is achieved by a variety of agents including pharmacologic agents, biophysical agents (laser photoirradiation or radioisotopes) and immunologic agents. Bone marrow purging is used in both autologous and allogeneic BONE MARROW TRANSPLANTATION.
Colony-Forming Units Assay
Graft vs Host Disease
Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.
A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells. (From The Merck Manual, 2006)
Hematopoietic Stem Cell Transplantation
Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.
A malignancy of mature PLASMA CELLS engaging in monoclonal immunoglobulin production. It is characterized by hyperglobulinemia, excess Bence-Jones proteins (free monoclonal IMMUNOGLOBULIN LIGHT CHAINS) in the urine, skeletal destruction, bone pain, and fractures. Other features include ANEMIA; HYPERCALCEMIA; and RENAL INSUFFICIENCY.
Leukemia, Myeloid, Acute
Synthetic or natural materials for the replacement of bones or bone tissue. They include hard tissue replacement polymers, natural coral, hydroxyapatite, beta-tricalcium phosphate, and various other biomaterials. The bone substitutes as inert materials can be incorporated into surrounding tissue or gradually replaced by original tissue.
Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.
Granulocyte Colony-Stimulating Factor
A glycoprotein of MW 25 kDa containing internal disulfide bonds. It induces the survival, proliferation, and differentiation of neutrophilic granulocyte precursor cells and functionally activates mature blood neutrophils. Among the family of colony-stimulating factors, G-CSF is the most potent inducer of terminal differentiation to granulocytes and macrophages of leukemic myeloid cell lines.
Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
Bone Morphogenetic Proteins
Bone-growth regulatory factors that are members of the transforming growth factor-beta superfamily of proteins. They are synthesized as large precursor molecules which are cleaved by proteolytic enzymes. The active form can consist of a dimer of two identical proteins or a heterodimer of two related bone morphogenetic proteins.
Precursor of an alkylating nitrogen mustard antineoplastic and immunosuppressive agent that must be activated in the LIVER to form the active aldophosphamide. It has been used in the treatment of LYMPHOMA and LEUKEMIA. Its side effect, ALOPECIA, has been used for defleecing sheep. Cyclophosphamide may also cause sterility, birth defects, mutations, and cancer.
Bone Morphogenetic Protein 2
Mesenchymal Stromal Cells
Bone-marrow-derived, non-hematopoietic cells that support HEMATOPOETIC STEM CELLS. They have also been isolated from other organs and tissues such as UMBILICAL CORD BLOOD, umbilical vein subendothelium, and WHARTON JELLY. These cells are considered to be a source of multipotent stem cells because they include subpopulations of mesenchymal stem cells.
Differentiation antigens residing on mammalian leukocytes. CD stands for cluster of differentiation, which refers to groups of monoclonal antibodies that show similar reactivity with certain subpopulations of antigens of a particular lineage or differentiation stage. The subpopulations of antigens are also known by the same CD designation.
The production of red blood cells (ERYTHROCYTES). In humans, erythrocytes are produced by the YOLK SAC in the first trimester; by the liver in the second trimester; by the BONE MARROW in the third trimester and after birth. In normal individuals, the erythrocyte count in the peripheral blood remains relatively constant implying a balance between the rate of erythrocyte production and rate of destruction.
Blood Cell Count
A single, unpaired primary lymphoid organ situated in the MEDIASTINUM, extending superiorly into the neck to the lower edge of the THYROID GLAND and inferiorly to the fourth costal cartilage. It is necessary for normal development of immunologic function early in life. By puberty, it begins to involute and much of the tissue is replaced by fat.
Precursor Cell Lymphoblastic Leukemia-Lymphoma
Leukemia, Myelogenous, Chronic, BCR-ABL Positive
Clonal hematopoetic disorder caused by an acquired genetic defect in PLURIPOTENT STEM CELLS. It starts in MYELOID CELLS of the bone marrow, invades the blood and then other organs. The condition progresses from a stable, more indolent, chronic phase (LEUKEMIA, MYELOID, CHRONIC PHASE) lasting up to 7 years, to an advanced phase composed of an accelerated phase (LEUKEMIA, MYELOID, ACCELERATED PHASE) and BLAST CRISIS.
An alkylating agent having a selective immunosuppressive effect on BONE MARROW. It has been used in the palliative treatment of chronic myeloid leukemia (MYELOID LEUKEMIA, CHRONIC), but although symptomatic relief is provided, no permanent remission is brought about. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), busulfan is listed as a known carcinogen.
The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS. (from The Dictionary of Cell Biology, Lackie and Dow, 3rd ed.)
Specialized forms of antibody-producing B-LYMPHOCYTES. They synthesize and secrete immunoglobulin. They are found only in lymphoid organs and at sites of immune responses and normally do not circulate in the blood or lymph. (Rosen et al., Dictionary of Immunology, 1989, p169 & Abbas et al., Cellular and Molecular Immunology, 2d ed, p20)
Granulocyte-Macrophage Colony-Stimulating Factor
An acidic glycoprotein of MW 23 kDa with internal disulfide bonds. The protein is produced in response to a number of inflammatory mediators by mesenchymal cells present in the hemopoietic environment and at peripheral sites of inflammation. GM-CSF is able to stimulate the production of neutrophilic granulocytes, macrophages, and mixed granulocyte-macrophage colonies from bone marrow cells and can stimulate the formation of eosinophil colonies from fetal liver progenitor cells. GM-CSF can also stimulate some functional activities in mature granulocytes and macrophages.
Mice, Inbred Strains
Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations, or by parent x offspring matings carried out with certain restrictions. All animals within an inbred strain trace back to a common ancestor in the twentieth generation.
Glycoproteins found in a subfraction of normal mammalian plasma and urine. They stimulate the proliferation of bone marrow cells in agar cultures and the formation of colonies of granulocytes and/or macrophages. The factors include INTERLEUKIN-3; (IL-3); GRANULOCYTE COLONY-STIMULATING FACTOR; (G-CSF); MACROPHAGE COLONY-STIMULATING FACTOR; (M-CSF); and GRANULOCYTE-MACROPHAGE COLONY-STIMULATING FACTOR; (GM-CSF).
Identification of the major histocompatibility antigens of transplant DONORS and potential recipients, usually by serological tests. Donor and recipient pairs should be of identical ABO blood group, and in addition should be matched as closely as possible for HISTOCOMPATIBILITY ANTIGENS in order to minimize the likelihood of allograft rejection. (King, Dictionary of Genetics, 4th ed)
Mesenchymal Stem Cell Transplantation
Disease Models, Animal
Formation of LYMPHOCYTES and PLASMA CELLS from the lymphoid stem cells which develop from the pluripotent HEMATOPOIETIC STEM CELLS in the BONE MARROW. These lymphoid stem cells differentiate into T-LYMPHOCYTES; B-LYMPHOCYTES; PLASMA CELLS; or NK-cells (KILLER CELLS, NATURAL) depending on the organ or tissues (LYMPHOID TISSUE) to which they migrate.
Either of a pair of compound bones forming the lateral (left and right) surfaces and base of the skull which contains the organs of hearing. It is a large bone formed by the fusion of parts: the squamous (the flattened anterior-superior part), the tympanic (the curved anterior-inferior part), the mastoid (the irregular posterior portion), and the petrous (the part at the base of the skull).
Combined Modality Therapy
A group of genetically identical cells all descended from a single common ancestral cell by mitosis in eukaryotes or by binary fission in prokaryotes. Clone cells also include populations of recombinant DNA molecules all carrying the same inserted sequence. (From King & Stansfield, Dictionary of Genetics, 4th ed)
Hematopoietic Stem Cell Mobilization
White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.
Any of a group of malignant tumors of lymphoid tissue that differ from HODGKIN DISEASE, being more heterogeneous with respect to malignant cell lineage, clinical course, prognosis, and therapy. The only common feature among these tumors is the absence of giant REED-STERNBERG CELLS, a characteristic of Hodgkin's disease.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Erythroid Precursor Cells
The cells in the erythroid series derived from MYELOID PROGENITOR CELLS or from the bi-potential MEGAKARYOCYTE-ERYTHROID PROGENITOR CELLS which eventually give rise to mature RED BLOOD CELLS. The erythroid progenitor cells develop in two phases: erythroid burst-forming units (BFU-E) followed by erythroid colony-forming units (CFU-E); BFU-E differentiate into CFU-E on stimulation by ERYTHROPOIETIN, and then further differentiate into ERYTHROBLASTS when stimulated by other factors.
Polymerase Chain Reaction
In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
Stem Cell Factor
Reverse Transcriptase Polymerase Chain Reaction
High-molecular weight glycoproteins uniquely expressed on the surface of LEUKOCYTES and their hemopoietic progenitors. They contain a cytoplasmic protein tyrosine phosphatase activity which plays a role in intracellular signaling from the CELL SURFACE RECEPTORS. The CD45 antigens occur as multiple isoforms that result from alternative mRNA splicing and differential usage of three exons.
Vitamin K-dependent calcium-binding protein synthesized by OSTEOBLASTS and found primarily in BONES. Serum osteocalcin measurements provide a noninvasive specific marker of bone metabolism. The protein contains three residues of the amino acid gamma-carboxyglutamic acid (Gla), which, in the presence of CALCIUM, promotes binding to HYDROXYAPATITE and subsequent accumulation in BONE MATRIX.
Proto-Oncogene Proteins c-kit
A protein-tyrosine kinase receptor that is specific for STEM CELL FACTOR. This interaction is crucial for the development of hematopoietic, gonadal, and pigment stem cells. Genetic mutations that disrupt the expression of PROTO-ONCOGENE PROTEINS C-KIT are associated with PIEBALDISM, while overexpression or constitutive activation of the c-kit protein-tyrosine kinase is associated with tumorigenesis.
Mice homozygous for the mutant autosomal recessive gene "scid" which is located on the centromeric end of chromosome 16. These mice lack mature, functional lymphocytes and are thus highly susceptible to lethal opportunistic infections if not chronically treated with antibiotics. The lack of B- and T-cell immunity resembles severe combined immunodeficiency (SCID) syndrome in human infants. SCID mice are useful as animal models since they are receptive to implantation of a human immune system producing SCID-human (SCID-hu) hematochimeric mice.
Adhesives used to fix prosthetic devices to bones and to cement bone to bone in difficult fractures. Synthetic resins are commonly used as cements. A mixture of monocalcium phosphate, monohydrate, alpha-tricalcium phosphate, and calcium carbonate with a sodium phosphate solution is also a useful bone paste.
Myeloid Progenitor Cells
Stem Cell Transplantation
The transfer of STEM CELLS from one individual to another within the same species (TRANSPLANTATION, HOMOLOGOUS) or between species (XENOTRANSPLANTATION), or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). The source and location of the stem cells determines their potency or pluripotency to differentiate into various cell types.
Formation of MYELOID CELLS from the pluripotent HEMATOPOIETIC STEM CELLS in the BONE MARROW via MYELOID STEM CELLS. Myelopoiesis generally refers to the production of leukocytes in blood, such as MONOCYTES and GRANULOCYTES. This process also produces precursor cells for MACROPHAGE and DENDRITIC CELLS found in the lymphoid tissue.
Deliberate prevention or diminution of the host's immune response. It may be nonspecific as in the administration of immunosuppressive agents (drugs or radiation) or by lymphocyte depletion or may be specific as in desensitization or the simultaneous administration of antigen and immunosuppressive drugs.
Antineoplastic Combined Chemotherapy Protocols
Alveolar Bone Loss
Family of RNA viruses that infects birds and mammals and encodes the enzyme reverse transcriptase. The family contains seven genera: DELTARETROVIRUS; LENTIVIRUS; RETROVIRUSES TYPE B, MAMMALIAN; ALPHARETROVIRUS; GAMMARETROVIRUS; RETROVIRUSES TYPE D; and SPUMAVIRUS. A key feature of retrovirus biology is the synthesis of a DNA copy of the genome which is integrated into cellular DNA. After integration it is sometimes not expressed but maintained in a latent state (PROVIRUSES).
Graft vs Host Reaction
The process of generating white blood cells (LEUKOCYTES) from the pluripotent HEMATOPOIETIC STEM CELLS of the BONE MARROW. There are two significant pathways to generate various types of leukocytes: MYELOPOIESIS, in which leukocytes in the blood are derived from MYELOID STEM CELLS, and LYMPHOPOIESIS, in which leukocytes of the lymphatic system (LYMPHOCYTES) are generated from lymphoid stem cells.
Non-antibody proteins secreted by inflammatory leukocytes and some non-leukocytic cells, that act as intercellular mediators. They differ from classical hormones in that they are produced by a number of tissue or cell types rather than by specialized glands. They generally act locally in a paracrine or autocrine rather than endocrine manner.
Hematopoietic Cell Growth Factors
These growth factors comprise a family of hematopoietic regulators with biological specificities defined by their ability to support proliferation and differentiation of blood cells of different lineages. ERYTHROPOIETIN and the COLONY-STIMULATING FACTORS belong to this family. Some of these factors have been studied and used in the treatment of chemotherapy-induced neutropenia, myelodysplastic syndromes, and bone marrow failure syndromes.
A class of statistical procedures for estimating the survival function (function of time, starting with a population 100% well at a given time and providing the percentage of the population still well at later times). The survival analysis is then used for making inferences about the effects of treatments, prognostic factors, exposures, and other covariates on the function.
A pyrimidine nucleoside analog that is used mainly in the treatment of leukemia, especially acute non-lymphoblastic leukemia. Cytarabine is an antimetabolite antineoplastic agent that inhibits the synthesis of DNA. Its actions are specific for the S phase of the cell cycle. It also has antiviral and immunosuppressant properties. (From Martindale, The Extra Pharmacopoeia, 30th ed, p472)
Severe Combined Immunodeficiency
Group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels. It is inherited as an X-linked or autosomal recessive defect. Mutations occurring in many different genes cause human Severe Combined Immunodeficiency (SCID).
Gene Expression Regulation
Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, environmental exposure and its effects, disease diagnosis, metabolic processes, substance abuse, pregnancy, cell line development, epidemiologic studies, etc.
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Precursor Cells, B-Lymphoid
Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging.
One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.
Bone Morphogenetic Protein 7
Multipotent Stem Cells
Specialized stem cells that are committed to give rise to cells that have a particular function; examples are MYOBLASTS; MYELOID PROGENITOR CELLS; and skin stem cells. (Stem Cells: A Primer [Internet]. Bethesda (MD): National Institutes of Health (US); 2000 May [cited 2002 Apr 5]. Available from: http://www.nih.gov/news/stemcell/primer.htm)
Congenital disorder affecting all bone marrow elements, resulting in ANEMIA; LEUKOPENIA; and THROMBOPENIA, and associated with cardiac, renal, and limb malformations as well as dermal pigmentary changes. Spontaneous CHROMOSOME BREAKAGE is a feature of this disease along with predisposition to LEUKEMIA. There are at least 7 complementation groups in Fanconi anemia: FANCA, FANCB, FANCC, FANCD1, FANCD2, FANCE, FANCF, FANCG, and FANCL. (from Online Mendelian Inheritance in Man, http://www.ncbi.nlm.nih.gov/entrez/dispomim.cgi?id=227650, August 20, 2004)
Dose-Response Relationship, Drug
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Macrophage Colony-Stimulating Factor
A mononuclear phagocyte colony-stimulating factor (M-CSF) synthesized by mesenchymal cells. The compound stimulates the survival, proliferation, and differentiation of hematopoietic cells of the monocyte-macrophage series. M-CSF is a disulfide-bonded glycoprotein dimer with a MW of 70 kDa. It binds to a specific high affinity receptor (RECEPTOR, MACROPHAGE COLONY-STIMULATING FACTOR).
Green Fluorescent Proteins
Bone marrow angiogenesis and mast cell density increase simultaneously with progression of human multiple myeloma. (1/9035)Immunohistochemical, cytochemical and ultrastructural data showing vivid angiogenesis and numerous mast cells (MCs) in the bone marrow of 24 patients with active multiple myeloma (MM) compared with 34 patients with non-active MM and 22 patients with monoclonal gammopathy of undetermined significance (MGUS) led us to hypothesize that angiogenesis parallels progression of MM, and that MCs participate in its induction via angiogenic factors in their secretory granules. (+info)
Granulocyte/macrophage colony-stimulating factor and interleukin-3 correct osteopetrosis in mice with osteopetrosis mutation. (2/9035)Although young mice homozygous for the osteopetrosis (op) mutation usually developed prominent osteopetrosis, its severity was markedly reduced in aged op/op mice. This age-associated reversal of osteopetrosis was accompanied by the expansion of bone marrow cavities and increased numbers of tartrate-resistant acid phosphatase (TRAP)-positive cells and of macrophages in the bone marrow. The TRAP-positive cells were mononuclear and developed ruffled borders and numerous vesicles, vacuoles, and granules. Enzyme-linked immunosorbent assay demonstrated a significant elevation of serum granulocyte/ macrophage colony-stimulating factor (GM-CSF) and interleukin (IL)-3 levels in the aged op/op mice. To examine whether GM-CSF and/or IL-3 could correct osteopetrosis in young op/op mice, 5 ng of recombinant murine (rm)GM-CSF and/or 100 ng of rmIL-3 were injected daily into young op/op mice. In these treated young op/op mice, the bone marrow cavities were expanded significantly at 2 weeks after administration, associated with significantly increased numbers of TRAP-positive cells and bone marrow macrophages. TRAP-positive cells increased in number with days after injection. These results suggest that GM-CSF and IL-3 induce the development of osteoclasts to correct osteopetrosis in the op/op mice with aging. (+info)
Organ-selective homing defines engraftment kinetics of murine hematopoietic stem cells and is compromised by Ex vivo expansion. (3/9035)Hematopoietic reconstitution of ablated recipients requires that intravenously (IV) transplanted stem and progenitor cells "home" to organs that support their proliferation and differentiation. To examine the possible relationship between homing properties and subsequent engraftment potential, murine bone marrow (BM) cells were labeled with fluorescent PKH26 dye and injected into lethally irradiated hosts. PKH26(+) cells homing to marrow or spleen were then isolated by fluorescence-activated cell sorting and assayed for in vitro colony-forming cells (CFCs). Progenitors accumulated rapidly in the spleen, but declined to only 6% of input numbers after 24 hours. Although egress from this organ was accompanied by a simultaneous accumulation of CFCs in the BM (plateauing at 6% to 8% of input after 3 hours), spleen cells remained enriched in donor CFCs compared with marrow during this time. To determine whether this differential homing of clonogenic cells to the marrow and spleen influenced their contribution to short-term or long-term hematopoiesis in vivo, PKH26(+) cells were sorted from each organ 3 hours after transplantation and injected into lethally irradiated Ly-5 congenic mice. Cells that had homed initially to the spleen regenerated circulating leukocytes (20% of normal counts) approximately 2 weeks faster than cells that had homed to the marrow, or PKH26-labeled cells that had not been selected by a prior homing step. Both primary (17 weeks) and secondary (10 weeks) recipients of "spleen-homed" cells also contained approximately 50% higher numbers of CFCs per femur than recipients of "BM-homed" cells. To examine whether progenitor homing was altered upon ex vivo expansion, highly enriched Sca-1(+)c-kit+Lin- cells were cultured for 9 days in serum-free medium containing interleukin (IL)-6, IL-11, granulocyte colony-stimulating factor, stem cell factor, flk-2/flt3 ligand, and thrombopoietin. Expanded cells were then stained with PKH26 and assayed as above. Strikingly, CFCs generated in vitro exhibited a 10-fold reduction in homing capacity compared with fresh progenitors. These studies demonstrate that clonogenic cells with differential homing properties contribute variably to early and late hematopoiesis in vivo. The dramatic decline in the homing capacity of progenitors generated in vitro underscores critical qualitative changes that may compromise their biologic function and potential clinical utility, despite their efficient numerical expansion.

Bone marrow ribonucleic acid polymerase. Effect of testosterone on nucleotide incorporation into nuclear RNA. (4/9035)The incorporation of 3H-UTP into RNA by isolated rat bone marrow nuclei is stimulated by testosterone. This effect is hormone and tissue specific. Using alpha-amanitine and different ionic strength conditions it was found that testosterone enhances preferentially RNA polymerase I activity. The sedimentation pattern of RNA isolated from bone marrow nuclei shows that the synthesis of RNA species within the 14-30 S range is mainly stimulated by the hormone. (+info)
In irradiation chimeras, K or D regions of the chimeric host, not of the donor lymphocytes, determine immune responsiveness of antiviral cytotoxic T cells. (5/9035)The H-2 haplotype of the chimeric host determines the responder phenotype of maturing T cells. Spleen cells of chimeric mice formed when (K(k) nonresponder to D(b) x K(b) responder to D(b) plus vaccinia)F(1) bone marrow cells were used to reconstitute K(b)D(b) (C57BL/6 D(b) responder) irradiated recipients generated high levels of D(b) plus vaccinia virus-specific cytotoxic T cells. The same stem cells used to reconstitute K(k)D(b) (B10.A (2R) D(b) nonresponder) irradiated recipients resulted in spleen cells that responded well to K plus vaccinia, but responsiveness to D(b) was low. A generally low response to D(k) plus vaccinia, which seems to be regulated by D(k), was confirmed in chimeras. Thus, K(d)D(d) (D(d) plus vaccinia responder) stem cells differentiating in a K(d)D(k) chimeric host failed to generate a measurable response to D(k) plus vaccinia. In contrast, stem cells from K(d)D(k) (D(k) plus vaccinia low responders) differentiating in a K(d)D(d) (K(d) and D(d) high responders to vaccinia) host do generate responsiveness to D(d) plus vaccinia. These results indicate that in chimeras, the Ir phenotype is independent of the donor T cell's Ir genotype, and that thymic selection of a T cell's restriction specificity for a particular H-2 allele of the chimeric host also defines that T cell's/r phenotype.

Hydroxyapatite-coated femoral stems. Histology and histomorphometry around five components retrieved at post mortem. (6/9035)We performed a histological and histomorphometric examination in five cadaver specimens of the femoral and acetabular components and the associated tissue which had been recovered between 3.3 and 6.2 years after primary total hip arthroplasty (THA) using a proximal hydroxyapatite (HA)-coated titanium alloy implant. All had functioned well during the patients' life. All the stems were fixed in the femur and showed osseointegration of both the proximal and distal parts. The amount of residual HA was greatest in the distal metaphyseal sections, indicating that the rate of bone remodelling may be the main factor causing loss of HA. The level of activity of the patient was the only clinical factor which correlated with loss of coating. The percentage of bone-implant osseointegration was almost constant, regardless of the amount of HA residue, periprosthetic bone density or the time of implantation. HA debris was seldom observed and if present did not cause any adverse or inflammatory reaction. Partial debonding did occur in one case as a result of a polyethylene-induced inflammatory reaction. (+info)
Mutant N-ras induces myeloproliferative disorders and apoptosis in bone marrow repopulated mice. (7/9035)Mutations that activate the N-ras oncogene are among the most frequently detected genetic alterations in human acute myeloid leukemias (AMLs), Philadelphia chromosome-negative myeloproliferative disorders (MPDs), and myelodysplastic syndromes (MDSs). However, because N-ras has not been shown to induce these disorders in an in vivo model, the role of N-ras in the evolution of myeloid leukemia is unclear. To investigate the potential of N-ras to induce myeloid leukemia, lethally irradiated mice were reconstituted with bone marrow (BM) cells infected with a retroviral vector carrying activated N-ras. Approximately 60% of these mice developed hematopoietic disorders, including severe MPDs resembling human chronic myelogenous leukemia (CML) or AML with differentiation (French-American-British [FAB] classification M2). Other reconstituted mice succumbed to hematopoietic defects that were pathologically similar to human MDSs. The latter disorders appeared to be due to a myeloid impairment that was demonstrated by enumeration of day-12 colony-forming units-spleen (CFU-S) and by in vitro colony assays. A high level of apoptosis associated with thymic atrophy and peripheral blood (PB) lymphopenia was also evident in N-ras reconstituted mice. Our results are consistent with a model in which antiproliferative effects are a primary consequence of N-ras mutations and secondary transforming events are necessary for the development of myeloid leukemia. This is the first report of an in vivo model for N-ras induced MPD and leukemia. (+info)
Quantitative polymerase chain reaction for the detection of micrometastases in patients with breast cancer. (8/9035)PURPOSE: Previous reports have indicated that reverse transcriptase polymerase chain reaction (RT-PCR) for cytokeratin 19 (CK-19) may be useful in the management of patients with breast cancer. However, the specificity of this technique is low, principally because of a high rate of false-positive results. To improve the specificity of this assay, we developed a quantitative RT-PCR methodology that enables an estimate to be made of the number of CK-19 transcripts in blood and bone marrow samples. PATIENTS AND METHODS: We examined 45 peripheral-blood samples and 30 bone marrow samples from patients with a variety of nonneoplastic conditions using nested RT-PCR for CK-19. We also examined bone marrow and peripheral-blood samples from 23 patients with primary breast cancer and peripheral-blood samples from 37 patients with metastatic breast cancer. The number of CK-19 transcripts was estimated in positive specimens by competitive PCR and normalized to the number of ABL transcripts as an internal control for the quality and quantity of cDNA. RT-PCR results were compared with the numbers of CK-19-positive cells detected by immunocytochemistry. RESULTS: Analysis of samples from patients without cancer enabled us to define an upper limit for the background ratio of CK-19 to ABL transcripts (1:1,000 for blood samples and 1:1,600 for bone marrow samples). Using these figures as cut-off points, elevated CK-19: ABL ratios were detected in peripheral-blood samples of 20 of 37 (54%) patients with metastatic breast cancer and in bone marrow samples of 14 of 23 (61%) patients with primary breast cancer. Only three of 23 (13%) primary breast cancer peripheral-blood samples and none of the control samples were positive by these criteria. Only two of 23 patients (9%) with primary breast cancer showed immunocytochemically detectable cells in the blood; 10 of 23 (43%) showed immunocytochemically detectable cells in the bone marrow. Of 36 patients with metastatic breast cancer, eight (22%) showed positive events. CONCLUSION: Quantitative RT-PCR for CK-19 detects a percentage of patients with breast cancer and may enable the progression or regression of the disease to be monitored. (+info)
Biopsy, bone marrow (Bone marrow biopsy) - Tests & Procedures
Bone marrow biopsy and bone marrow aspiration are procedures to collect and examine bone marrow - the spongy tissue inside some of your larger bones. Bone marrow biopsy and bone marrow aspiration can show whether your bone marrow is healthy and making normal amounts of blood cells. Doctors use bone marrow biopsy and aspiration to diagnose and monitor blood and marrow diseases, including some cancers.
Bone marrow - Simple English Wikipedia, the free encyclopedia
There are two types of bone marrow. Red marrow is made mostly of myeloid tissue (which makes new blood cells). Red blood cells, platelets, and most white blood cells are created by red marrow. Yellow marrow is made mainly of fat cells. Both types of bone marrow contain many blood vessels and capillaries. When a person is born, all of their bone marrow is red. As the person ages, more and more of the bone marrow changes to the yellow type. By adulthood, about half of a persons bone marrow is red. Red marrow is found mainly in the flat bones - like the hip bone, breast bone, skull, ribs, vertebra (the bones that make up the spinal column), and shoulder blades - and in the cancellous (spongy) material at the ends of the long bones like the femur (thigh bone) and humerus (upper forearm bone). Yellow marrow is found inside the hollow middle section, or medullary cavity of the long bones. In cases of severe blood loss, the body can change yellow marrow back to red marrow so that more blood cells ...
Bone Marrow Aspirate Concentrate (BMA/BMAC) - Los Angeles, CA | C. Thomas Vangsness, Jr., M.D.
Bone marrow aspirate concentrate (BMA/BMAC) is perhaps the most popular stem cell injection available today. The treatment involves injecting the patients own bone marrow cells into the injured area with the hope that it will help regrow tissue or reduce inflammation. The procedure involves two steps: (1) patients are lightly anesthetized and bone marrow is removed through a needle from the bone, most commonly the iliac crest of the patients hip, and then (2) the bone marrow is processed to concentrate the cells. After the bone marrow has been centrifuged (spun in a circle to separate the various blood contents), the BMA/BMAC is put into a syringe and injected into the affected body part.. Bone marrow contains progenitor cells, which are cells that have been primed to become specific cells. A small fraction of these cells (about 1% of the total cells in bone marrow) are mesenchymal stem cells, which can become cartilage, bone, and tendon cells. It is thought that these mesenchymal ...
What is Bone Marrow?
Certain diseases of the bone marrow like leukemia, multiple myeloma, myelodysplastic syndrome (MDS), pancytopenia, anemia etc. require examination of the bone marrow tissue. This is called bone marrow aspiration or bone marrow biopsy. A needle is used to withdraw samples of the marrow from within the bone. This is often a very painful process.. Bone marrow is suppressed with the use of cancer chemotherapy. This leads to severe drop in production of RBCs (leading to anemia), WBCs (leading to increased risk of life threatening infections) and platelets (leading to risk of bleeding tendencies).. With advent of medical science it is possible now to transplant the bone marrow in diseased individuals. This process has shown success in a number of cancer patients..

What You Should Know About Bone Marrow Biopsy for the Staging of Lymphoma - UNM Comprehensive Cancer Center
Cancers that begin in cells of the lymph system are referred to as malignant lymphomas. The lymph system includes the spleen, thymus, tonsils, bone marrow, lymph nodes and circulating white blood cells called lymphocytes. Lymphocytes and the lymph system are part of the immune system that protects the body from disease and infection. Cancers of the lymph system are referred to as Hodgkins lymphoma or non-Hodgkins lymphoma.. Newly diagnosed lymphoma patients are required to undergo a number of tests and procedures to ensure accurate diagnosis and staging. Tests may include a lymph node biopsy, blood tests, a CT scan, PET scan and bone marrow biopsy. Some patients report that of these, the most difficult is the bone marrow biopsy.. Bone marrow, found in the center of most large bones, is a spongy material that produces red blood cells, white blood cells and platelets. A bone marrow biopsy is used to evaluate how well the bone marrow is functioning and to determine if lymphoma is present. This is ...
Aging | The effects of dietary fatty acids on bone, hematopoietic marrow and marrow adipose tissue in a murine model of senile...
Purpose: Marrow adipose tissue (MAT) expansion and associated lipotoxicity are important drivers of age-related bone loss and hematopoietic bone marrow (HBM) atrophy. Fish oil and borage oil (rich in ω3 fatty acids) can partially prevent aged-related bone loss in SAMP8 mice. However, whether preservation of bone mass in this progeria model is associated with MAT volumes remains unknown.Results: MAT volume fraction (MAT%) showed a negative association with hematopoietic bone marrow (HBM%;r=-0.836, p<0.001) and bone (bone%;r=-0.344, p=0.013) volume fractions.Adjusting for multiple comparisons, bone% was higher and MAT% was lower in Fish oil (FO)-supplemented groups vs. controls (p<0.001). HBM% did not differ significantly between the four groups. However, in the group supplemented with FO, HBM comprised higher fractions and MAT constituted lower fractions of total marrow vs. controls (p<0.001).Conclusion: Feeding FO-enriched diet prevented age-related bone and HBM loss,
Bone Marrow Collection and Examination
1. Bone marrow is commonly collected and examined when abnormalities are found in the circulating blood. The most common abnormality is a persistent shortage of one of the blood cell types. This is a serious situation and may be due to a problem in the bone marrow. Examination of marrow can often provide information about the underlying cause, and may help to predict the outcome.. 2. Bone marrow is also collected and examined to look for certain types of cancer. Some cancers start right in the cells of the bone marrow and other cancers spread to the bone marrow from elsewhere in the body. Cancer that starts in the bone marrow is sometimes called leukemia. Examination of the bone marrow helps to identify the cancer, and reveals how seriously the marrow is affected.. 3. Occasionally, bone marrow is collected and examined to investigate other problems such as persistent fever, unexplained weight loss, high blood calcium levels (see article on Hypercalcemia), and high serum protein level (see ...
Bone Marrow</span><span class=w-nav...
The two types of bone marrow are red marrow (Latin: medulla ossium rubra), which consists mainly of hematopoietic tissue, and yellow marrow (Latin: medulla ossium flava), which is mainly made up of fat cells. Red blood cells, platelets, and most white blood cells arise in red marrow. Both types of bone marrow contain numerous blood vessels and capillaries. At birth, all bone marrow is red. With age, more and more of it is converted to the yellow type; only around half of adult bone marrow is red. Red marrow is found mainly in the flat bones, such as the pelvis, sternum, cranium, ribs, vertebrae and scapulae, and in the cancellous (spongy) material at the epiphyseal ends of long bones such as the femur and humerus. Yellow marrow is found in the medullary cavity, the hollow interior of the middle portion of short bones. In cases of severe blood loss, the body can convert yellow marrow back to red marrow to increase blood cell production.. ...

The Cost of Bone Marrow Transplant in India
Some people experience bone marrow problems and their bone marrow is destroyed. It is the semi-solid tissue that is found in the spongy areas of bones. Some diseases of the bone marrow are not curable such as multiple myeloma. So, this part should be replaced. The bone marrow transplant procedure is performed to the patients who experience severe problems such as cancer. So, they take cells that are normally found in bone marrow and these cells are filtered. If these cells become germ-free after filtering, then they are placed in the same location of the patient. Otherwise, the cells of other persons are transplanted in the region. Bone marrow transplant The bone marrow produces three types of cells namely the red blood, white blood and platelets. This operation involves complications also and sometimes, it is life-threatening. Some of the complications that arise are graft host disease and graft failure. The blood forming cells of the patient are extracted and replaced with the germ-free ...
Increased PD-1+Tim-3+ exhausted T cells in bone marrow may influence the clinical outcome of patients with AML | Biomarker...
Altered expression of T cell immune inhibitory receptors may result in immunosuppression and associate with the poor prognosis of leukemia patients in which the leukemic bone marrow (BM) microenvironment may contribute to such immunosuppression. We found higher numbers of programmed death-1 (PD-1) + exhausted T cells in peripheral blood (PB) from acute myeloid leukemia (AML) patients. To investigate the leukemic BM influence on immunosuppression, we further compared the distributions of PD-1 and T cell immunoglobulin mucin-3 (Tim-3) and the exhausted T cell phenotype in PB and BM from AML patients and characterized their relationship with clinical outcome. PB and BM samples from 15 patients with newly diagnosed AML were collected and analyzed for the expression of PD-1, Tim-3, CD244, and CD57 on CD3+, CD4+, and CD8+ T cells by multicolor flow cytometry. The proportions of PD-1 + CD3+ and PD-1 + CD8+ T cells were significantly higher in BM compared with PB. Similarly, higher PD-1 + CD244 + CD3+ and PD-1

The bone marrow plays a unique role within the immune system. We compared the phenotype and function of virus-specific CD8(+) T cells from matched samples of human peripheral blood and bone marrow. Analysis of virus-specific memory CD8(+) T cells showed widely divergent partition of antigen-specific populations between blood and bone marrow. T cells specific for Epstein-Barr virus (EBV) lytic antigens were enriched 3-fold in marrow compared with blood, whereas the response to EBV latent epitopes was equivalent between the 2 compartments. No difference in EBV viral load or expression of the EBV lytic protein was observed between blood and bone marrow. In direct contrast, although cytomegalo-virus (CMV)-specific T cells were the largest virus-specific population within peripheral blood, they were reduced by 60% within marrow. Bone marrow T cells were found to exhibit a unique CCR5(+)CXCR6(+)CXCR3(-) homing phenotype which has not been observed on T cells from other secondary lymphoid organs or peripheral

Bone Marrow Aspirate</span><span class=w-nav...
The Marrow Cellution™ Bone Marrow Aspiration System is a novel bone marrow access and retrieval device that incorporates features designed to minimize limitations of traditional trocar needles. Traditional needles aspirate primarily through an open-ended cannula, which leads to excess blood collection that requires additional manipulation (i.e. centrifugation or chemical separation in a laboratory). By overcoming these limitations, Marrow Cellution™ maximizes stem- and progenitor-cell recovery and minimizes peripheral blood infiltration.. Marrow Cellution™ accesses aspirate flow collected exclusively laterally, as the tip of the aspiration cannula is closed. This allows marrow collection perpendicular to and around the channel created by the tip of the device, thus avoiding excess peripheral blood infiltration. The device also incorporates technology to precisely reposition the retrieval cannula within the marrow space after each aspiration. These features achieve a clinicians desire for ...

Frontiers | Exercise Regulation of Marrow Adipose Tissue | Endocrinology
Despite association with low bone density and skeletal fractures, marrow adipose tissue (MAT) remains poorly understood. The marrow adipocyte originates from the mesenchymal stem cell pool (MSC) that gives rise also to osteoblasts, chondrocytes, and myocytes among other cell types. To date, the presence of MAT has been attributed to preferential biasing of MSC into the adipocyte rather than osteoblast lineage, thus negatively impacting bone formation. Here we focus on understanding the physiology of MAT in the setting of exercise, dietary interventions and pharmacologic agents that alter fat metabolism. The beneficial effect of exercise on musculoskeletal strength is known: exercise induces bone formation, encourages growth of skeletally-supportive tissues, inhibits bone resorption and alters skeletal architecture through direct and indirect effects on a multiplicity of cells involved in skeletal adaptation. MAT is less well studied due to the lack of reproducible quantification techniques. In recent
Bone Marrow Transplant for Children | Phoenix Childrens Hospital
Once suitable stem cells are found, your child will receive high doses of chemotherapy or radiation (sometimes both) to destroy existing bone marrow. This gives the new bone marrow cells room to grow. This may be called ablative or myeloablative therapy. It stops new blood cells from being made. The bone marrow becomes empty. An empty marrow is needed to make room for the new stem cells to grow and create a new system to make new blood cells. Next, stem cells are given to your child through an IV in a large vein, often in the chest. This is called a central venous catheter. Getting the stem cells is like having a blood transfusion. The stem cells find their way into the bone marrow. They begin growing and making new, healthy blood cells. During infusion of the bone marrow, your child may have:. ...

We have evaluated the usefulness of bilateral rather than unilateral posterior iliac spine trephine biopsies in searching for lymphoma and other neoplastic diseases in the bone marrow. Two hundred and eighty-two patients with these diseases were studied. Tumor was found on only one side in 22% of patients with non-Hodgkins malignant lymphoma, in 43% of patients with Hodgkins disease, and in 36% of patients with other neoplastic processes. Thus, the second biopsy yields an additional 11% to 22% of positive biopsies. We conclude that bilateral trephine bone marrow biopsies should be routinely performed when searching for tumor in the bone marrow. ...
Identification of CD22 Ligands on Bone Marrow Sinusoidal Endothelium Implicated in CD22-dependent Homing of Recirculating B...
Here we present evidence that CD22 is a specific receptor involved in the homing of long-lived recirculating B cells to the bone marrow. Our demonstration that CD22 ligands are constitutively expressed on endothelial cells in the bone marrow, but not in other organs, raises the attractive possibility that CD22 can function as a classical homing receptor for the bone marrow by targeting cells to the appropriate microenvironment. It has been reported that IgD+ recirculating cells are found in the extravascular space, mainly in perisinusoidal locations ((15)). The interaction with CD22 ligands on endothelial cells could be an important first step before transmigration of B cells into the bone marrow parenchyma. Another possibility is that CD22 serves as a retention signal, preventing the reexit of B cells from the bone marrow.. The reason for the incomplete block in B cell homing after the in vivo treatments could be related to the relatively low affinity of the carbohydrate binding region of CD22 ...

Bone Marrow Transplant - SUONO TV
Blood cancer is also known as leukemia which starts forming in the bone marrow of the body. Leukemia generally begins to develop when a major issue occurs during the manufacturing process of blood cells. This abnormal creation of blood cells alters the DNA of the white blood cells thereby causing damage to it. The bone marrow in the body becomes a hotbed for excessive cell division and multiplication. This entire exercise leads to the degeneration of good blood cells, and at the same time gives rise to growth and multiplication of anomalous cells.. A time comes when the bone marrow gets filled with anomalous cells which render the white blood cells to become ineffective. White blood cells are responsible for immunity in our bodies. When they become powerless to produce antibodies due to excessive anomalous cells, our body defense system gets destroyed.. Treatment of Leukemia- Bone Marrow Transplant.

The typical procedure will start with a course of very high doses of chemotherapy, specifically tailored to obliterate the patients existing bone marrow. This procedure is called myeloablation, and is meant to kill the diseased bone marrow and affected blood cells. At this point, because of the lack of bone marrow and the cells that comprise it, including the immune cells, the patient becomes very susceptible to infection. This actually is the major cause of death and disability for HSCT.. After a few days, the hematopoietic stem cells, which are the stem cells that will become the patients new bone marrow, are given to the patient. Depending on the disease, this could be from the patients own stem cells, or from a matched donor. And once these have been implanted, they then start to function as the new bone marrow with potentially curative results.. The success rates for HSCT differ and would depend on a lot of factors, some are inherent in the patient, biology of the disease and facilities ...

Femur Window Chamber Model for In Vivo Cell Tracking in the Murine Bone Marrow - DaCosta Lab
Bone marrow is a complex organ that contains various hematopoietic and non-hematopoietic cells. These cells are involved in many biological processes, including hematopoiesis, immune regulation and tumor regulation. Commonly used methods for understanding cellular actions in the bone marrow, such as histology and blood counts, provide static information rather than capturing the dynamic action of multiple cellular components in vivo. To complement the standard methods, a window chamber (WC)-based model was developed to enable serial in vivo imaging of cells and structures in the murine bone marrow. This protocol describes a surgical procedure for installing the WC in the femur, in order to facilitate long-term optical access to the femoral bone marrow. In particular, to demonstrate its experimental utility, this WC approach was used to image and track neutrophils within the vascular network of the femur, thereby providing a novel method to visualize and quantify immune cell trafficking and ...

Bone marrow examination - Wikipedia
Bone marrow examination refers to the pathologic analysis of samples of bone marrow obtained by bone marrow biopsy (often called a trephine biopsy) and bone marrow aspiration. Bone marrow examination is used in the diagnosis of a number of conditions, including leukemia, multiple myeloma, lymphoma, anemia, and pancytopenia. The bone marrow produces the cellular elements of the blood, including platelets, red blood cells and white blood cells. While much information can be gleaned by testing the blood itself (drawn from a vein by phlebotomy), it is sometimes necessary to examine the source of the blood cells in the bone marrow to obtain more information on hematopoiesis; this is the role of bone marrow aspiration and biopsy. Bone marrow samples can be obtained by aspiration and trephine biopsy. Sometimes, a bone marrow examination will include both an aspirate and a biopsy. The aspirate yields semi-liquid bone marrow, which can be examined by a pathologist under a light microscope and analyzed by ...

TY - JOUR. T1 - Bone marrow aplasia and Ewings sarcoma occuring prior to stem cell transplant. AU - Wolff, Lawrence. AU - Moore, T. B.. AU - Magenis, E.. PY - 1999/2. Y1 - 1999/2. N2 - The association of secondary malignancies with bone marrow aplasia after bone marrow transplant is a known entity. We report a 19 year old man who was diagnosed as having bone marrow aplasia. The initial and subsequent evaluations of his bone marrow and blood showed normal chromosomes, normal mitocycin C stimulation, and normal serum acid hemolysis test. In March, 1995, he was treated with antilymphocyte globulin (ALG), cyclosporine (CSA), glucocorticosteroids (G) and gmcsf. His marrow quickly showed trilineage recovery. However by February, 1996, his peripheral blood counts and bone marrow again indicated marrow failure. The very hypocellular marrow showed only a rare CD34 positive cell and the marrow lymphocytes were entirely T suppressor cells (CD3, CD8). Again the bone marrow responded to ALG, CSA, G, and ...
Bone Marrow Failure Research Program, Congressionally Directed Medical Research Programs
Bone marrow failure is a general term covering many diseases. Bone marrow, the sponge-like tissue found inside bones, contains blood-forming stem cells that develop into red blood cells, white blood cells, and platelets. Disorders affecting the stem cells can, in turn, lead to bone marrow failure-rare, potentially life-threatening diseases in which the bone marrow stops functioning or produces abnormal blood cells. These diseases are classified into two major categories: acquired bone marrow failure and inherited bone marrow failure. Acquired bone marrow failure may be caused by a variety of factors including exposure to certain chemicals, environmental toxins, viruses, or by autoimmune responses. Acquired bone marrow failure diseases include aplastic anemia, myelodysplasia, paroxysmal nocturnal hemoglobinuria and pure red cell aplasia. Inherited forms of bone marrow failure arise from specific alterations or abnormalities of genes. The most common inherited bone marrow failure disorders include ...
Bone marrow suppression - Wikipedia
Bone marrow suppression also known as myelotoxicity or myelosuppression, is the decrease in production of cells responsible for providing immunity (leukocytes), carrying oxygen (erythrocytes), and/or those responsible for normal blood clotting (thrombocytes). Bone marrow suppression is a serious side effect of chemotherapy and certain drugs affecting the immune system such as azathioprine. The risk is especially high in cytotoxic chemotherapy for leukemia. Nonsteroidal anti-inflammatory drugs (NSAIDs), in some rare instances, may also cause bone marrow suppression. The decrease in blood cell counts does not occur right at the start of chemotherapy because the drugs do not destroy the cells already in the bloodstream (these are not dividing rapidly). Instead, the drugs affect new blood cells that are being made by the bone marrow. When myelosuppression is severe, it is called myeloablation. Many other drugs including common antibiotics may cause bone marrow suppression. Unlike chemotherapy the ...

About Bone Marrow Stem Cell Transplant
Bone marrow transplant (BMT) can strengthen the body to fight cancer by replacing the blood building cells in the body that are destroyed by chemotherapy and radiation treatments, which are used to kill the cancer cells, with healthy stem cells found in bone marrow.. In a bone marrow transplant, the patients diseased bone marrow is destroyed and healthy bone marrow stem cells are infused into the patients blood-stream. In a successful BMT transplant, the new bone marrow migrates to the cavities of the large bones and begins producing healthy, normal blood cells.. Types of Bone Marrow Transplants. There are several types of bone marrow transplants, also referred to as stem-cell transplants. Which type is used for any given patient depends on the specific patients disease as well as other factors such as the patients age and the availability of a suitable donor. Learn more ,,. Resources.

Enhancement of bone marrow allografts from nude mice into mismatched recipients by T cells void of graft-versus-host activity ...
Transplantation of 8 x 10(6) C57BL/6-Nu+/Nu+ (nude) bone marrow cells into C3H/HeJ recipients after conditioning with 8 Gy of total body irradiation has resulted in a markedly higher rate of graft rejection or graft failure compared to that found in recipients of normal C57BL/6 or C57BL/6-Bg+/Bg+ (beige) T-cell-depleted bone marrow. Mixing experiments using different numbers of nude bone marrow cells with or without mature thymocytes (unagglutinated by peanut agglutinin) revealed that engraftment of allogeneic T-cell-depleted bone marrow is T-cell dependent. To ensure engraftment, a large inoculum of nude bone marrow must be supplemented with a trace number of donor T cells, whereas a small bone marrow dose from nude donors requires a much larger number of T cells for engraftment. Marked enhancement of donor type chimerism was also found when F1 thymocytes were added to nude bone marrow cells, indicating that the enhancement of bone marrow engraftment by T cells is not only mediated by ...

Bone Marrow Transplant - Swarovski Sparkles
For some patients, bone marrow transplants become necessary because of several reasons. It could be because of some severe blood disorders including certain types of blood cancers like leukemia and lymphoma. Further, many people have to go in for high-dose chemotherapy. These high dosages may be quite effective in getting rid of dangerous cancer cells. However, they also wipe out healthy cells and in many cases, the entire bone marrow is wiped out and destroyed. In such situations, the only option is to go in for a bone marrow transplant. When a person needs high dosage chemotherapy, often doctors go in for bone marrow transplant to replace the destroyed bone marrow with new ones. This will help the patients to ensure that after the therapy, the body gets high quality and fresh bone marrow. The same can be used for the production of high-quality blood stem cells from the blood cancer bone marrow transplant. This will help in augmenting the supply of red blood cells, white blood cells, and ...
Antiendothelial cell antibodies induce apoptosis of bone marrow endothelial progenitors in systemic sclerosis.
OBJECTIVE: Patients with systemic sclerosis (SSc) have significantly fewer and functionally impaired endothelial progenitor cells (EPC) in peripheral blood and bone marrow; further, endothelial apoptosis seems to play a primary role in the pathogenesis of vascular damage. We investigated whether the failure of bone marrow EPC is related to their apoptotic phenotype and analyzed the possible mechanisms inducing apoptosis.METHODS: The presence of apoptotic cells was investigated in bone marrow aspirates taken from patients with SSc; microvessel density (MVD) and the immunohistochemical expression of vascular endothelial growth factor (VEGF) were also measured in bone marrow biopsies. A correlation between EPC apoptosis and the presence of antiendothelial cell antibodies (AECA) was also investigated.RESULTS: We confirmed the presence of bone marrow EPC dysfunction in SSc, while hematopoiesis was not impaired. Bone marrow studies showed a high percentage of apoptotic progenitors, no signs of ...

Blood and Bone Marrow Transplantation - Guide to Internet Resources for Cancer - CancerIndex
There are many different types of blood cell, but they all develop from stem cells. Most of these stem cells are found in the bone marrow (the soft inside part of the bone), although some are found in the blood (peripheral blood stem cells). Chemotherapy and/or radiotherapy damages normal cells as well as cancer cells. At high doses the bone marrow may be damaged or destroyed, and the patient may not be able to produce the necessary blood cells. In a Bone marrow transplant (BMT), marrow containing healthy stem cells is infused to replace those damaged by the high dose therapy, so that the patient can produce blood cells again. If it is not possible to use marrow, a peripheral blood stem cell transplant (PBSCT) may be given. There are 3 types of transplant: (1) Allogenic transplants are where marrow is donated by another person; (2) Autologous transplants involve cells being taken from the patient, stored, and then reinfused following high-dose therapy; and (3) Syngenic transplants are where the ...
Vertebral bone marrow fat fraction changes in postmenopausal women with breast cancer receiving combined aromatase inhibitor...
Quantification of vertebral bone marrow (VBM) water-fat composition has been proposed as advanced imaging biomarker for osteoporosis. Estrogen deficiency is the primary reason for trabecular bone loss in postmenopausal women. By reducing estrogen levels aromatase inhibitors (AI) as part of breast cancer therapy promote bone loss. Bisphosphonates (BP) are recommended to counteract this adverse drug effect. The purpose of our study was to quantify VBM proton density fat fraction (PDFF) changes at the lumbar spine using chemical shift encoding-based water-fat MRI (CSE-MRI) and bone mineral density (BMD) changes using dual energy X-ray absorptiometry (DXA) related to AI and BP treatment over a 12-month period. Twenty seven postmenopausal breast cancer patients receiving AI therapy were recruited for this study. 22 subjects completed the 12-month study. 14 subjects received AI and BP (AI+BP), 8 subjects received AI without BP (AI-BP). All subjects underwent 3 T MRI. An eight-echo 3D spoiled gradient-echo
Bone marrow examination - Wikipedia
A bone marrow biopsy may be done in a health care providers office or in a hospital. Informed consent for the procedure is typically required. The patient is asked to lie on their abdomen (prone position) or on their side (lateral decubitus position). The skin is cleansed, and a local anesthetic such as lidocaine or procaine is injected to numb the area. Patients may also be pretreated with analgesics and/or anti-anxiety medications, although this is not a routine practice. Typically, the aspirate is performed first. An aspirate needle is inserted through the skin using manual pressure and force until it abuts the bone. Then, with a twisting motion of clinicians hand and wrist, the needle is advanced through the bony cortex (the hard outer layer of the bone) and into the marrow cavity. Once the needle is in the marrow cavity, a syringe is attached and used to aspirate (suck out) liquid bone marrow. A twisting motion is performed during the aspiration to avoid excess content of blood in the ...

A Characteristic Bone Marrow Finding in the Hurler Syndrome | American Academy of Pediatrics
Seventeen of eighteen patients with the Hurler syndrome demomstrated a characteristic, perhaps pathognomonic, accumulation of mucopolysaccharide granules in their bone marrow. These can be easily recognized by conventional hematologic techniques for preparation and staining of bone marrow. Since large amounts of bone marrow material can be obtained, bone marrow aspirates could conceivably provide an accessible source of tissue mucopolysaccharide for analysis and study. Reilly bodies are so infrequently found that we feel their importance as a diagnostic feature has been overemphasized.. ...
JC virus in bone marrow of HIV-positive and HIV-negative patients | BMC Proceedings | Full Text

Sonic hedgehog promotes chondrogenesis of rabbit bone marrow stem cells in a rotary cell culture system | BMC Developmental...
Sonic hedgehog (Shh) is an important signalling protein involved in the induction of early cartilaginous differentiation. Herein, we demonstrate that Shh markedly induces chondrogenesis of rabbit bone marrow stromal cells (BMSCs) under microgravity conditions, and promotes cartilage regeneration. In the rotary cell culture system (RCCS), chondrogenic differentiation was revealed by stronger Toluidine Blue and collagen II immunohistochemical staining in the Shh transfection group, and chondroinductive activity of Shh was equivalent to that of TGF-β. Western blotting and qRT-PCR analysis results verified the stronger expression of Sox9, aggrecan (ACAN), and collagen II in rabbit BMSCs treated with Shh or TGF-β in a microgravity environment. Low levels of chondrogenic hypertrophy, osteogenesis, and adipogenesis-related factors were detected in all groups. After transplantation in vivo, histological analysis revealed a significant improvement in cartilage and subchondral repair in the Shh transfection

Bone marrow cells routinely help with wound healing
Bone marrow has been studied for a number of purposes in recent years because it is rich in stem cells - cells that can go on to become many different kinds of cells. In order to conduct this research, Isik and colleagues obtained a strain of mice whose bodies glow green under fluorescent light. The researchers removed bone marrow from the mice and then performed a stem cell transplant into a genetically identical strain of normal mice, whose cells do not glow green. Afterward, only the bone marrow of the transplanted mice glowed green inside the bodies of the mice, allowing researchers to track the bone marrow cells throughout the body. Researchers found green cells throughout the body, but observed that the highest concentration of bone marrow cells was in normal skin ...

Each year, thousands of patients turn to bone marrow/stem cell transplants to treat cancer and other life-threatening illnesses. While a BMT can be a very effective treatment, it is a long and demanding process for patients and their loved ones. Since its founding in 1992, the National Bone Marrow Transplant Link has helped thousands of individuals worldwide through its comprehensive web site, publications for patients and caregivers, Emmy Award winning video, volunteer peer support programs, resource referrals and educational forums. The National Bone Marrow Transplant Link is funded through private, foundation and corporate donations ...
Depth-dependent concentrations of hematopoietic stem cells in the adult skeleton: Implications for active marrow dosimetry. -...
PURPOSE The hematopoietically active (or red) bone marrow is the target tissue assigned in skeletal dosimetry models for assessment of stochastic effects (leukemia induction) as well as tissue reactions (marrow toxicity). Active marrow, however, is in reality a surrogate tissue region for specific cell populations, namely the hematopoietic stem and progenitor cells. Present models of active marrow dosimetry implicitly assume that these cells are uniformly localized throughout the marrow spaces of trabecular spongiosa. Data from Watchman et al. and Bourke et al., however, clearly indicate that there is a substantial spatial concentration gradient of these cells with the highest concentrations localized near the bone trabeculae surfaces. The purpose of the present study was thus to explore the dosimetric implications of these spatial gradients on active marrow dosimetry. METHODS Images of several bone sites from a 45-yr female were retagged to group active marrow voxels into 50 μm increments of marrow
New Ruling Allows Bone Marrow Donors to be Compensated
Bone marrow donors may be compensated for their donations.. This ruling will increase the odds of patients finding matches when in need of transplants, which must be a genetic match.. The court said that new technologies for transplanting bone marrow make the tissue more like blood and less like an organ. The National Organ Transplant Act prohibits compensation for human organs, such as kidneys, but allows payment for renewable tissues such as blood.. A California nonprofit MoreMarrowDonors.org, sued U.S. Attorney General Eric Holder in 2009, challenging the ban on compensation for bone marrow donations.. They argued that allowing financial incentives for bone marrow donation was crucial because of the extreme difficulty of finding a genetic match.. The suit said the ban violated the U.S. Constitution because it treated bone marrow as a human organ while allowing payments for blood, sperm and eggs.. ...

Bone marrow transplants are used to treat patients with leukemia, multiple myeloma, immune deficiency disorders, aplastic anemia, lymphomas and some cases of breast or ovarian cancer. During a bone marrow transplant the patients existing bone marrow is destroyed and the new healthy bone marrow is infused into the patients blood stream. If the transplant is successful the new bone marrow will begin to produce healthy blood cells ...
Mesenchymal and haematopoietic stem cells form a unique bone marrow niche. - Semantic Scholar
The cellular constituents forming the haematopoietic stem cell (HSC) niche in the bone marrow are unclear, with studies implicating osteoblasts, endothelial and perivascular cells. Here we demonstrate that mesenchymal stem cells (MSCs), identified using nestin expression, constitute an essential HSC niche component. Nestin(+) MSCs contain all the bone-marrow colony-forming-unit fibroblastic activity and can be propagated as non-adherent mesenspheres that can self-renew and expand in serial transplantations. Nestin(+) MSCs are spatially associated with HSCs and adrenergic nerve fibres, and highly express HSC maintenance genes. These genes, and others triggering osteoblastic differentiation, are selectively downregulated during enforced HSC mobilization or beta3 adrenoreceptor activation. Whereas parathormone administration doubles the number of bone marrow nestin(+) cells and favours their osteoblastic differentiation, in vivo nestin(+) cell depletion rapidly reduces HSC content in the bone marrow.
