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 ...

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 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 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 ...

This experiential VR training and assessment is designed to help learners acquire the necessary skills to perform bone marrow aspiration and biopsy procedures..

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.

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 transplants, also called stem cell transplants, treat over 80 diseases and disorders, including certain forms of cancer. A patients diseased bone marrow is replaced with healthy stem cells from a donor.. Mr. Speaker, I rise in the House today to raise awareness for the bone marrow registry. On any given day, there are about 1,000 Canadians on a waiting list for a bone marrow transplant. Three out of four patients rely on external bone marrow donors. Finding a potential donor is not an easy job, especially among South Asians, where theres a one-in-a-million chance because of the extremely low donor registration rate.. I would like to recognize a charity, Match For Marrow, from the GTA, which has partnered with Canadian Blood Services and other international organizations to raise awareness for bone marrow registries. ...

Our first blog post highlights the life-saving bone marrow transplant procedure.. The Important Work of a Bone Marrow Transplant. For patients with certain conditions such sickle cell disease, lymphoma, aplastic anemia, and neuroblastoma, myelodysplastic syndrome (MDS), and including possible fatal blood cancers, like lymphoma and leukemia, a bone marrow transplant offers a chance for a cure and a longer life. Its also sometimes necessary to repair damaged marrow (where blood cells are manufactured) as a result of chemotherapy for cancer, as was the case with Good Morning Americas host Robin Roberts. We are happy to hear that Robin is expected back to Good Morning Amerca on February 20th after taking time off for her bone marrow transplant.. Bone Marrow Transplant Donor Awareness.

Bone marrow aspiration is the removal of a small amount of the liquid portion of the bone marrow through a needle inserted into the bone. It can be done to collect bone marrow for stem cell transplantation or chromosomal analysis, or to monitor treatment for certain types of blood disorders.. The bone marrow sample is examined under a microscope to obtain information to:. ...

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 ...

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 ...

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 ...

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

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 ...

About Stem Cell Transplantations (SCT). In the bone marrow, there is approximately one stem cell in every 100,000 blood cells. The bone marrow in the breast bone, skull, hips, ribs, and spine contains the stem cells.. In the blood stream, the number of stem cells is about 1/100 of that in the bone marrow. Transplantation of these stem cells from the blood stream is sometimes used in addition to, or instead of, traditional bone marrow transplantation.. Peripheral blood stem cell transplantation differs from traditional bone marrow transplantation only in the method by which the stem cells are harvested for infusion into the patient.. Harvesting stem cells from bone marrow requires a surgical procedure.. Harvesting stem cells from the blood stream is accomplished by a process called apheresis.. The patient is connected to a cell separation machine via a needle in each arm. Blood is taken from one arm, circulated through the machine to remove the stem cells, and the remaining blood cells are ...

These stem cells are special because they can mature into ...

ABSTRACT Introduction; Hematological abnormalities are a common complication of HIV infection. Bone marrow abnormalities occur in all stages of HIV infection. Present work was carried out to study the bone marrow abnormalities in patients with HIV/AIDS. Methods: 160 patients of HIV +ve were included in the study. A complete blood count, relevant biochemical investigations, CD4 counts were done, besides a thorough history and clinical examination. HIV positive patients were classified as those having AIDS and those without AIDS according to NACO criteria. Bone marrow examination was performed for indication of anemia, leucopenia, pancytopenia and thrombocytopenia. Results: As per CDC criteria 59.81% patients had AIDS in 107 patients. The most common hematological abnormality was anemia, seen in 93.12% patients. Bone marrow was normocellular in 79.06% of non-AIDS and 79.68% of AIDS, hypocellular in 13.95%.Thrombocytopenia was seen in 4 cases of ART (4.93%) and 3 cases (4.68%) of AIDS group. ...

Bone Marrow Transplantation. For bone marrow transplantation, not only native stem cells of the patient are used, but also stem cells of another person can be transplanted, if particular criteria are met. Transplantations are categorized according to the source of stem cell.. How bone marrow is obtained for transplantation and how peripheral stem cells are collected for transplantation?. Stem cells to be used in transplantation can be collected from bone marrow, peripheral blood and umbilical cord blood of mothers who deliver recently. Although stem cells collected from peripheral blood are usually primarily preferred, stem cells collected from bone marrow will be preferred in benign diseases, such as aplastic anemia, thalassemia and immune deficiency syndromes.. Peripheral stem cell is harvested with apheresis device after cytokines, which help stem cells in bone marrow migrate to peripheral blood and are referred as granulocyte colony stimulant factor (G-CSF), are used.. For patients in need ...

What is bone marrow transplant?. A Bone Marrow Transplant is a medical procedure that is performed for replacing the infected or damaged bone marrow. Bone marrow can be destroyed by complex chemotherapy or infected by a disease. Blood stem cells are transplanted in this process that produces healthy blood cells in the bone marrow and encourage growth in new marrow. Transplants are of two types; autologous transplant (usage of own stem cells) and allogeneic transplant (usage of stem cells from the donor) ...

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.. ...

Of 41 HIV+ patients, 38 were male (93%) and indications for BM biopsies were lymphoma (20), pancytopenia (8), anemia (6), MGUS (2), polycythemia (2), leucopenia (1), splenomegaly (1), and thrombocytopenia (1). Mean age was 47 (range 32-71), mean CD4 count 211 (2-928), 27% had undetectable plasma HIV RNA, and 75% were on HAART. The 47 HIV- controls, matched for indications for BM biopsy, included 32 males (65%), and mean age was 56 (range 27-93). Quantitative PCR detected JCV DNA in BM samples of 19/41 (46%) HIV+ vs 3/47 (6%) of HIV- (p , 0.001). Preliminary immunohistochemistry (IHC) experiments suggest that JCV T antigen is detectable in a fraction of JCV DNA positive bone marrows samples, while JCV VP1 protein was not. Furthermore, JCV was detected by double IHC in some of the plasma cells, myeloid, and lymphoid cells. We then tested fresh BM aspirates, blood and urine samples from 30 HIV- and 6 HIV+ patients.

Here, the protein-coding genes expressed in the bone marrow are described and characterized, together with examples of immunohistochemically stained tissue sections that visualize protein expression patterns of proteins that correspond to genes with elevated expression in the bone marrow. Transcript profiling and RNA-data analyses based on normal human tissues have been described previously (Fagerberg et al., 2013). Analyses of mRNA expression including over 99% of all human protein-coding genes was performed using deep RNA sequencing of 172 individual samples corresponding to 37 different human normal tissue types. RNA sequencing results of 4 fresh frozen tissues representing normal bone marrow was compared to 168 other tissue samples corresponding to 36 tissue types, in order to determine genes with elevated expression in bone marrow. A tissue-specific score, defined as the ratio between mRNA levels in bone marrow compared to the mRNA levels in all other tissues, was used to divide the genes ...

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

Among many cell populations constituting the bone and bone marrow microenvironment, osteoblasts (originated from mesenchymal stem cells) and osteoclasts (originated from hematopoietic stem cells) have been the main research focus for pro-tumorigenic roles. Recently, increasing evidence further elucidates that hematopoietic lineage cells as well as stromal cells in the bone marrow mediate distinct but critical functions in tumor growth, metastasis, angiogenesis and apoptosis in the bone microenvironment. This review article summarizes the key evidence describing differential roles of bone marrow cells, including hematopoietic stem cells (HSCs), ...

RATIONALE: Giving chemotherapy and total-body irradiation before a donor bone marrow transplant or peripheral blood stem cell transplant helps stop the growth of cancer and abnormal cells and helps stop the patients immune system from rejecting the donors stem cells. When certain stem cells from a donor are infused into the patient they may help the patients bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the bodys normal cells. Removing the T cells from the donor cells before transplant may stop this from happening.. PURPOSE: This randomized phase III trial is studying donor bone marrow that is treated in the laboratory using two different devices to compare how well they work in treating patients who are undergoing a donor bone marrow transplant for hematologic cancer. ...

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 ...

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

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 ...

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.

BACKGROUND: Pancytopenia is not a disease entity but a triad of findings that may result from various disease processes, primarily or secondarily involving the bone marrow. Bone marrow aspiration and biopsy evaluation along with good clinical correlation is of utmost importance to evaluate the causes of pancytopenia and planning further investigations.. AIMS: The present study was a prospective clinicohaematological study undertaken to analyse the various causes of pancytopenia by evaluating bone marrow aspiration and biopsy and correlating with clinical findings, complete blood counts and peripheral blood picture.. MATERIALS AND METHODS: Fifty patients of pancytopenia were included in the study in which relevant history and physical examination findings were recorded. Bone marrow aspiration and biopsy were performed simultaneously in all cases. Perls stain was done in all cases and special stains like MPO, PAS and reticulin were also done wherever necessary.. RESULTS AND CONCLUSION: The ...

The cells in the blood and lymph system originate from stem cells in the bone marrow. A bone marrow examination is performed to diagnose lymphoma, leukemia, and metastasis to bone marrow. The examination usually includes an aspiration and/or biopsy from the iliac crest. When diagnosing Hodgkins lymphoma, an aspirate and biopsy are taken from both sides. Sometimes, aspiration from the sternum is appropriate. In special cases, the aspiration is performed with the help of image guidance in cooperation with the nuclear medicine department. A bone marrow examination involves:. ...

TY - JOUR. T1 - In vivo reactivity of mouse natural killer (NK) cells against normal bone marrow cells. AU - Riccardi, C.. AU - Santoni, A.. AU - Barlozzari, T.. AU - Herberman, R. B.. PY - 1981/5/1. Y1 - 1981/5/1. N2 - An in vivo role for mouse natural killer (NK) cells in the rapid rejection of transplantable tumors has been previously demonstrated, using an assay of elimination of [125I]iododeoxyuridine-labeled tumor cells from the lungs and other organs. We have now used the same technique to examine the role of NK cells in in vivo clearance of syngeneic or allogeneic bone marrow cells from normal mice. The degree of clearance from the lungs or liver, at 4 hr after intravenous inoculation of radiolabeled bone marrow cells, correlated with the levels of NK activity in the recipients. Young CBA mice, with high NK activity, showed substantially more clearance of bone marrow cells than SJL mice, with low NK activity. Within the same strain, mice at 7 weeks of age had higher in vivo as well as in ...

Horowitz MC, Berry R, Holtrup B, Sebo Z, Nelson T, Fretz JA, Lindskog D, Kaplan JL, Ables GP, Rodeheffer MS, Rosen CJ.. Adipocyte. 2017 Jul 3;6(3):193-204.. PMID: 28872979. Adipocytes were identified in human bone marrow more than a century ago, yet until recently little has been known about their origin, development, function or interactions with other cells in the bone marrow. Little functional significance has been attributed to these cells, a paradigm that still persists today. However, we now know that marrow adipose tissue increases with age and in response to a variety of physiologic induction signals. Bone marrow adipocytes have recently been shown to influence other cell populations within the marrow and can affect whole body metabolism by the secretion of a defined set of adipokines. Recent research shows that marrow adipocytes are distinct from white, brown and beige adipocytes, indicating that the bone marrow is a distinct adipose depot. This review will highlight recent data ...

TY - JOUR. T1 - TGF beta 1 limits the expansion of the osteoprogenitor fraction in cultures of human bone marrow stromal cells. AU - Walsh, S.. AU - Jefferiss, C.. AU - Stewart, K.. AU - Beresford, J. N.. N1 - ID number: ISI:000181664900006. PY - 2003. Y1 - 2003. N2 - Currently, there is considerable interest in the possibility of using cultured human bone marrow stromal cells (BMSCs) for skeletal tissue engineering. However, the factors that regulate their ex vivo expansion and promote their osteogenic maturation remain poorly defined. Using BMSCs obtained from a large cohort of adult donors, the effects of transforming growth factor (TGF)beta1 on these processes have been determined. BMSCs were found to express TGFbeta receptors (TbetaRs) I, II, III (betaglycan) and CD105/endoglin. The expression of TbetaRs I and II, but not TbetaR III or endoglin, was linked to the cells state of maturation. Treatment with TGFbeta increased the colony-forming efficiency (CFE) of marrow cell suspensions but ...

Introduction: Diffuse large B-cell lymphoma (DLBCL), not otherwise specified, is a large B-cell lymphoma with a diffuse growth pattern and aggressive clinical course. It is divided in subgroups according to its morphology, immunophenotype, and primary site. Dissemination to bone marrow occurs in 11% to 35% of cases and can be of concordant or discordant morphology. Objective: To examine the association, the type of bone marrow involvement in relation to the primary site, morphology, immunohistochemistry of DLBCLs and to determine the cases of Epstein-Barr virus positive DLBCLs. Materials and Methods: We reviewed lymph node and extranodal biopsies as well as the respective bone marrow biopsies in all cases of DLBCL diagnosed in the Hospital General de México during the period from 2002 to 2010. We used immunohystochemistry for immunophenotype identification (Hanss algorithm) and an in-situ hybridization technique to detect presence of Epstein Barr encoded RNA (EBER). Results: We included 108 patients

snip}. {snip} Every year in the United States, about 12,000 people up to age 74 need bone marrow or umbilical cord blood transplants for survival.. Bone marrow donors go through one of two procedures when theyre found to be a match: a peripheral blood stem cell process, where the donor has a needle inserted into an arm that collects stem cells; or a surgical procedure, where the donor is put under anesthesia and then has bone marrow extracted from the lower back region. Most donors go through the first process. Each process often leaves the donor slightly bruised, but thats about the worst of it.. The likelihood of a person matching with an available donor on the Be The Match registry ranges from 19 to 80 percent, depending on their ethnicity, according to worldwide data from the organization.. {snip} In recent years, there have been numerous reports that the number of Black bone marrow donors is too low. Black people seeking a bone marrow transplant have about a 23 percent chance of finding ...

A cancer survivor who received a lifesaving bone marrow donation from someone she has never met has written a heartfelt poem to say thank you to the man who saved her life on World Bone Marrow Donor Day (15th September).. Kelly Coombes, a 28 year-old mother from Caerphilly, was diagnosed with acute myeloid leukaemia, a cancer of the white blood cells. After two rounds of chemotherapy to help moderate the illness, Kelly was told her best chance of survival was finding a suitable bone marrow donor for a lifesaving stem cell transplant.. After months of treatment, Kelly received the news that a bone marrow match had been found: All of a sudden when everything is really horrible, you get a little bit of hope and you feel empowered. It gives you an extra reason to fight.. Kelly received a bone marrow transplant which cured her illness.

Introduction Recent evidence has shown that bone marrow cells play critical roles during the inflammatory proliferative and remodeling phases of cutaneous wound healing. assays. The preparations examined were whole bone marrow (WBM) whole bone marrow (long term initiating/hematopoietic based) cultured cells (BMC) and bone marrow derived mesenchymal stem cells (BM-MSC). We also applied these bone marrow preparations in two murine models of radiation induced delayed wound healing to determine which had a greater effect on healing. Results Angiogenesis assays demonstrated that tube formation was stimulated by both WBM and BMC with WBM having the greatest effect. Scratch wound assays showed higher fibroblast migration at 24 48 and 72 hours in presence of WBM as compared to BM-MSC. WBM also appeared to stimulate a greater healing response than BMC and BM-MSC in a radiation induced delayed wound healing animal model. Conclusions These studies promise to help elucidate the role of stem cells during ...

TY - JOUR. T1 - Activation of non-canonical TGF-β1 signaling indicates an autoimmune mechanism for bone marrow fibrosis in primary myelofibrosis. AU - Ciaffoni, Fiorella. AU - Cassella, Elena. AU - Varricchio, Lilian. AU - Massa, Margherita. AU - Barosi, Giovanni. AU - Migliaccio, Anna Rita. PY - 2015/3/1. Y1 - 2015/3/1. N2 - Primary myelofibrosis (PMF) is characterized by megakaryocyte hyperplasia, dysplasia and death with progressive reticulin/collagen fibrosis in marrow and hematopoiesis in extramedullary sites. The mechanism of fibrosis was investigated by comparing TGF-β1 signaling of marrow and spleen of patients with PMF and of non-diseased individuals. Expression of 39 (23 up-regulated and 16 down-regulated) and 38 (8 up-regulated and 30 down-regulated) TGF-β1 signaling genes was altered in the marrow and spleen of PMF patients, respectively. Abnormalities included genes of TGF-β1 signaling, cell cycling and abnormal in chronic myeloid leukemia (. EVI1 and p21CIP) (both marrow and ...

Transforming growth factor beta (TGF-beta), an immunomodulator, has inhibitory as well as stimulatory effects on bone marrow cells. In this study, we demonstrate that TGF-beta 1 also is a bidirectional modulator of CSF receptor expression on murine bone marrow cells. TGF-beta 1 up-regulated granulocyte-macrophage (GM)-CSF receptor expression in a time- and dose-dependent manner, with a maximum up-regulation of 64% by 48 h at 20 ng/ml. In contrast, TGF-beta 1 down-modulated IL-3 and CSF-1 receptor expression by 54 and 55%, respectively, by 24 h. TGF-beta 1 did not affect G-CSF receptor expression, in agreement with its inability to affect G-CSF-induced proliferation. The CSF receptor modulation induced by TGF-beta 1 preceded its effects on CSF-stimulated proliferation. The effects of TGF-beta on CSF receptor expression were isoform dependent, thus TGF-beta 3 was a 10-fold more potent inhibitor of both IL-3-induced colony formation and IL-3 receptor expression than TGF-beta 1, whereas TGF-beta 1 was a

You might have come across patients suffering from sickle anemia who have no other option but to go in for bone marrow transplant. Whether it is sickle cell anemia or other types of blood disorders and blood cancers, there are reasons to believe that bone marrow transplant could be the only option. When a person suffers from acute anemia including sickle cell anemia, over a period of time, his or her life could be under threat. This is because this form of anemia and other forms of blood cancers lead to a massive shortage of white blood cells, red blood cells, and platelets. We need to understand these healthy cells are made in our bone marrow. The bone marrow is located within the hollow of our bones and they produce healthy red blood cells, white blood cells, platelets amongst other things. When a person gets impacted by various blood disorders, the bone marrow does not produce healthy cells and this leads to anemia and other problems.. What Are The Causes?. There are many reasons for the ...

IN their investigations of the fat composition and in vitro oxygen consumption of marrow from fed and fasted rabbits, Evans et al.1 observed a respiratory quotient of 0.85 for marrow cell suspensions incubated in the absence of glucose but in the presence of all the fatty material of whole marrow. The authors were unable to detect any uptake of fatty acid by the marrow cells and concluded that saturated fats were probably not degraded in the marrow for the production of local energy. In the work recorded here we have re-examined the question of in vitro uptake and oxidation of fatty acid by bone marrow cells. Our results indicate that fatty acid is taken up and oxidized by washed bone marrow cells suspended in a medium containing 5 per cent albumin as a carrier for fatty acid. Furthermore, we have found that glucose exerts a considerable influence on the rate of uptake and oxidation of fatty acid.

Objectives: Human bone marrow stromal cells (hBMSCs) are adherent fibroblast-like cells found in the bone marrow. They are a heterogeneous population of cells that includes a subset of osteoprogenitors. BMSCs have been widely used for tissue engineering, especially for bone regeneration. However, for clinical application currently, large quantities of hBMSCs are usually required for transplantation which is typically produced by serial passages of the cells ex vivo. We examined the effects of in vitro expansion on hBMSCs proliferation, multidifferentiation, and gene expression profiles. Methods: hBMSCs were harvested from surgical waste bone specimens from 3 healthy adults with IRB approval. The hBMSCs were cultured in α-MEM with 10% FBS and 1% penicillin-streptomycin. hBMSCs were trypsinized and passaged when they reached 70-80% confluence. Cells from early passage (p2 or 3) were compared with late passage (p7 or 8). MTT assay was used to determine the growth kinetics of hBMSCs. ...

TY - JOUR. T1 - NADPH oxidase 2 regulates bone marrow microenvironment following hindlimb ischemia. T2 - Role in reparative mobilization of progenitor cells. AU - Urao, Norifumi. AU - McKinney, Ronald D.. AU - Fukai, Tohru. AU - Ushio-Fukai, Masuko. PY - 2012/5/1. Y1 - 2012/5/1. N2 - Bone marrow (BM) microenvironment, which is regulated by hypoxia and proteolytic enzymes, is crucial for stem/progenitor cell function and mobilization involved in postnatal neovascularization. We demonstrated that NADPH oxidase 2 (Nox2)-derived reactive oxygen species (ROS) are involved in postischemic mobilization of BM cells and revascularization. However, role of Nox2 in regulating BM microenvironment in response to ischemic injury remains unknown. Here, we show that hindlimb ischemia of mice increases ROS production in both the endosteal and central region of BM tissue in situ, which is almost completely abolished in Nox2 knockout (KO) mice. This Nox2-dependent ROS production is mainly derived from Gr-1+myeloid ...

Bone marrow stromal cells (BMSCs) constitute a cell population routinely used as a representation of mesenchymal stem cells in vitro. They reside within the bone marrow cavity alongside hematopoietic stem cells (HSCs), which can give rise to red blood cells, immune progenitors, and osteoclasts. Thus, extractions of cell populations from the bone marrow results in a very heterogeneous mix of various cell populations, which can present challenges in experimental design and confound data interpretation. Several isolation and culture techniques have been developed in laboratories in order to obtain more or less homogeneous populations of BMSCs and HSCs invitro. Here, we present two methods for isolation of BMSCs and HSCs from mouse long bones: one method that yields a mixed population of BMSCs and HSCs and one method that attempts to separate the two cell populations based on adherence. Both methods provide cells suitable for osteogenic and adipogenic differentiation experiments as well as functional assays

Several functions have been proposed for the role of macrophage apoE synthesis in cholesterol homeostasis and its relation to atherosclerosis, including either proatherosclerotic or antiatherosclerotic functions.18-31 The present study confirms that hypercholesterolemia in apoE-deficient mice can be markedly reduced by transplantation with wild-type bone marrow, while heterozygous apoE-deficient bone marrow appeared to be nearly equally effective. We demonstrate that this reduction in cholesterol levels is accompanied by an increased recognition and uptake of (β)VLDL by parenchymal liver cells.. Following total body irradiation, aplasia of bone marrow develops within 2 to 3 days. BMT will lead to recovery of hematopoietic tissues after two distinct phases of engraftment.

A resident population of dendritic cells (DCs) has been identified in murine bone marrow, but its contribution to the regulation of hematopoiesis and establishment of the stem cell niche is largely unknown. Here, we show that murine bone marrow DCs are perivascular and have a type 2 conventional DC (cDC2) immunophenotype. RNA expression analysis of sorted bone marrow DCs showed that expression of many chemokines and chemokine receptors is distinct from that observed in splenic cDC2s, suggesting that bone marrow DCs might represent a unique DC population. A similar population of DCs was present in human bone marrow. Ablation of conventional DCs (cDCs) results in hematopoietic stem/progenitor cell (HSPC) mobilization that was greater than that seen with ablation of bone marrow macrophages, and cDC ablation also synergizes with granulocyte-colony stimulating factor to mobilize HSPCs. Ablation of cDCs was associated with an expansion of bone marrow endothelial cells and increased vascular ...

The bone marrow contains a multipotent stromal cell, commonly referred to as a mesenchymal stem cell (MSC). There has been recent interest in the clinical use of MSCs for cell-based therapy because: (1) bone marrow aspiration is a routine method used in medicine thereby allowing for easy accessibility to human MSCs; (2) MSCs are easily isolated and can expand to clinical scales in a relatively short period of time; (3) MSCs can be biopreserved without loss of potency and stored for point-of-care delivery; and (4) human trials of MSCs thus far have shown no adverse reactions to allogeneic versus autologous MSC transplants suggesting that therapy can cross histocompatibility barriers. This thesis describes the development of new modalities and indications for MSC-based treatments by leveraging the endogenous functions of these cells for therapeutic purposes. First, it is known that marrow stromal cells support hematopoiesis by secreting bioactive molecules that aid in the growth, differentiation, ...

Bone marrow stromal cells protect hematopoietic cells and provide drug resistance by delivering bunch of variable proteins. Thus, alterations of protein expression are typically associated with cell-cell signal transduction and regulation of cellular functions. Co-culture models of bone marrow stromal cells and hematopoietic cells are often used in studies of their crosstalk. Studies of altered protein expression initiated by stromal cell/hematopoietic cell interactions are an important new trend in microenvironmental research. There has been no report to date of global quantitative proteomics analysis of crosstalk between hematopoietic cells and stromal cells. In this study, we analyzed quantitative proteomes in a co-culture system of stromal HS5 cells and hematopoietic KG1a cells, and simultaneously tracked differentially expressed proteins in two types of cells before and after co-culture by stable isotope labeling by amino acids in cell culture (SILAC) method. We have shown that in co-cultured KG1a,

Purpose: : Cigarette smoke is the single greatest environmental risk factor for age-related macular degeneration, and the effects of smoking are partially retained years after cessation. We have shown that cigarette smoke causes more severe CNV in mice. One proposed mechanism for the long lasting effect of smoke is toxic damage to vascular cells or extracellular matrix in blood vessels, which would persist long after smoke cessation. Another possibility is smoke-related alterations in myeloid or vascular progenitors in the marrow. In this case, the long term consequences of smoke would be retained in the bone marrow, but not in the peripheral tissue. We performed an experiment to test this distinction. Methods: : We performed bone marrow transplantation (BMT) by isolating bone marrow from mice exposed to full stream cigarette smoke two hrs daily for four weeks transferred into normal, non-exposed recipients; or vice versa, marrow from non-exposed mice into smoke-exposed recipients. Then, ...

TY - JOUR. T1 - Role of the bone marrow microenvironment in multiple myeloma. AU - Roodman, G. David. PY - 2002/11/1. Y1 - 2002/11/1. N2 - On June 26-27, 2001, the Sixth Research Roundtable in Multiple Myeloma, entitled The Role of the Bone Microenvironment in Multiple Myeloma, was held and focused on the biology of cell-to-cell interactions, the mediators of bone disease, and novel treatment strategies for myeloma. Studies on cell-cell interactions showed that vascular cell adhesion molecule 1, expressed by local endothelial and stromal cells, binds to tumor cell surface integrins in which expression may be increased by tumor cell-derived chemokines such as macrophage inflammatory protein (MIP) 1α. These adhesive interactions increase production and release of vascular endothelial growth factor (VEGF). Studies on myeloma bone disease showed the ligand for receptor activator of nuclear transcription factor-κB (RANKL) was expressed on tumor cells and stromal cells associated with myeloma ...
