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.
Bone Marrow Cells
The hormone-responsive glandular layer of ENDOMETRIUM that sloughs off at each menstrual flow (decidua menstrualis) or at the termination of pregnancy. During pregnancy, the thickest part of the decidua forms the maternal portion of the PLACENTA, thus named decidua placentalis. The thin portion of the decidua covering the rest of the embryo is the decidua capsularis.
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.

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)
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.
The hollow thick-walled muscular organ in the female PELVIS. It consists of the fundus (the body) which is the site of EMBRYO IMPLANTATION and FETAL DEVELOPMENT. Beyond the isthmus at the perineal end of fundus, is CERVIX UTERI (the neck) opening into VAGINA. Beyond the isthmi at the upper abdominal end of fundus, are the FALLOPIAN TUBES.
Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.
Reverse Transcriptase Polymerase Chain Reaction
Colony-Forming Units Assay
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.
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.
The period from onset of one menstrual bleeding (MENSTRUATION) to the next in an ovulating woman or female primate. The menstrual cycle is regulated by endocrine interactions of the HYPOTHALAMUS; the PITUITARY GLAND; the ovaries; and the genital tract. The menstrual cycle is divided by OVULATION into two phases. Based on the endocrine status of the OVARY, there is a FOLLICULAR PHASE and a LUTEAL PHASE. Based on the response in the ENDOMETRIUM, the menstrual cycle is divided into a proliferative and a secretory phase.
Connective Tissue Cells
The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses. (Cline et al., Dictionary of Visual Science, 4th ed)
Gene Expression Regulation
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
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.
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.
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.
Bone Marrow Transplantation
Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.
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.
The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.
Insulin-Like Growth Factor Binding Protein 1
One of the six homologous proteins that specifically bind insulin-like growth factors (SOMATOMEDINS) and modulate their mitogenic and metabolic actions. The function of this protein is not completely defined. However, several studies demonstrate that it inhibits IGF binding to cell surface receptors and thereby inhibits IGF-mediated mitogenic and cell metabolic actions. (Proc Soc Exp Biol Med 1993;204(1):4-29)
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.
Transforming Growth Factor beta
A factor synthesized in a wide variety of tissues. It acts synergistically with TGF-alpha in inducing phenotypic transformation and can also act as a negative autocrine growth factor. TGF-beta has a potential role in embryonal development, cellular differentiation, hormone secretion, and immune function. TGF-beta is found mostly as homodimer forms of separate gene products TGF-beta1, TGF-beta2 or TGF-beta3. Heterodimers composed of TGF-beta1 and 2 (TGF-beta1.2) or of TGF-beta2 and 3 (TGF-beta2.3) have been isolated. The TGF-beta proteins are synthesized as precursor proteins.
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.
Lymphotoxin beta Receptor
A member of the tumor necrosis factor receptor superfamily. It has specificity for LYMPHOTOXIN ALPHA1, BETA2 HETEROTRIMER and TUMOR NECROSIS FACTOR LIGAND SUPERFAMILY MEMBER 14. The receptor plays a role in regulating lymphoid ORGANOGENESIS and the differentiation of certain subsets of NATURAL KILLER T-CELLS. Signaling of the receptor occurs through its association with TNF RECEPTOR-ASSOCIATED FACTORS.
A lymphohematopoietic cytokine that plays a role in regulating the proliferation of ERYTHROID PRECURSOR CELLS. It induces maturation of MEGAKARYOCYTES which results in increased production of BLOOD PLATELETS. Interleukin-11 was also initially described as an inhibitor of ADIPOGENESIS of cultured preadipocytes.
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.
Vascular Endothelial Growth Factor A
The original member of the family of endothelial cell growth factors referred to as VASCULAR ENDOTHELIAL GROWTH FACTORS. Vascular endothelial growth factor-A was originally isolated from tumor cells and referred to as "tumor angiogenesis factor" and "vascular permeability factor". Although expressed at high levels in certain tumor-derived cells it is produced by a wide variety of cell types. In addition to stimulating vascular growth and vascular permeability it may play a role in stimulating VASODILATION via NITRIC OXIDE-dependent pathways. Alternative splicing of the mRNA for vascular endothelial growth factor A results in several isoforms of the protein being produced.
One of a pair of excretory organs (mesonephroi) which grows caudally to the first pair (PRONEPHROI) during development. Mesonephroi are the permanent kidneys in adult amphibians and fish. In higher vertebrates, proneprhoi and most of mesonephroi degenerate with the appearance of metanephroi. The remaining ducts become WOLFFIAN DUCTS.

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.
Sex Cord-Gonadal Stromal Tumors
Neoplasms derived from the primitive sex cord or gonadal stromal cells of the embryonic GONADS. They are classified by their presumed histogenesis and differentiation. From the sex cord, there are SERTOLI CELL TUMOR and GRANULOSA CELL TUMOR; from the gonadal stroma, LEYDIG CELL TUMOR and THECOMA. These tumors may be identified in either the OVARY or the TESTIS.
Bone Morphogenetic Protein 2
Intercellular Signaling Peptides and Proteins
Regulatory proteins and peptides that are signaling molecules involved in the process of PARACRINE COMMUNICATION. They are generally considered factors that are expressed by one cell and are responded to by receptors on another nearby cell. They are distinguished from HORMONES in that their actions are local rather than distal.
A soluble factor produced by MONOCYTES; MACROPHAGES, and other cells which activates T-lymphocytes and potentiates their response to mitogens or antigens. Interleukin-1 is a general term refers to either of the two distinct proteins, INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The biological effects of IL-1 include the ability to replace macrophage requirements for T-cell activation.
Receptor, Platelet-Derived Growth Factor alpha
A membrane-bound or cytosolic enzyme that catalyzes the synthesis of CYCLIC ADP-RIBOSE (cADPR) from nicotinamide adenine dinucleotide (NAD). This enzyme generally catalyzes the hydrolysis of cADPR to ADP-RIBOSE, as well, and sometimes the synthesis of cyclic ADP-ribose 2' phosphate (2'-P-cADPR) from NADP.

Disease Models, Animal
Fluorescent Antibody Technique
Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.
Cell- and Tissue-Based Therapy
Stem Cell Niche
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.
Cells lining the outside of the BLASTOCYST. After binding to the ENDOMETRIUM, trophoblasts develop into two distinct layers, an inner layer of mononuclear cytotrophoblasts and an outer layer of continuous multinuclear cytoplasm, the syncytiotrophoblasts, which form the early fetal-maternal interface (PLACENTA).
Endometrial Stromal Tumors
Neoplasms of the endometrial stroma that sometimes involve the MYOMETRIUM. These tumors contain cells that may closely or remotely resemble the normal stromal cells. Endometrial stromal neoplasms are divided into three categories: (1) benign stromal nodules; (2) low-grade stromal sarcoma, or endolymphatic stromal myosis; and (3) malignant endometrial stromal sarcoma (SARCOMA, ENDOMETRIAL STROMAL).
Gene Expression Regulation, Neoplastic
Fibroblast Growth Factor 2
A single-chain polypeptide growth factor that plays a significant role in the process of WOUND HEALING and is a potent inducer of PHYSIOLOGIC ANGIOGENESIS. Several different forms of the human protein exist ranging from 18-24 kDa in size due to the use of alternative start sites within the fgf-2 gene. It has a 55 percent amino acid residue identity to FIBROBLAST GROWTH FACTOR 1 and has potent heparin-binding activity. The growth factor is an extremely potent inducer of DNA synthesis in a variety of cell types from mesoderm and neuroectoderm lineages. It was originally named basic fibroblast growth factor based upon its chemical properties and to distinguish it from acidic fibroblast growth factor (FIBROBLAST GROWTH FACTOR 1).
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).
Enzyme-Linked Immunosorbent Assay
An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
Matrix Metalloproteinase 9
Highly specialized EPITHELIAL CELLS that line the HEART; BLOOD VESSELS; and lymph vessels, forming the ENDOTHELIUM. They are polygonal in shape and joined together by TIGHT JUNCTIONS. The tight junctions allow for variable permeability to specific macromolecules that are transported across the endothelial layer.
Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm.
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.
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.
Oligonucleotide Array Sequence Analysis
Matrix Metalloproteinase 2
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.
Tumor Necrosis Factor-alpha
Serum glycoprotein produced by activated MACROPHAGES and other mammalian MONONUCLEAR LEUKOCYTES. It has necrotizing activity against tumor cell lines and increases ability to reject tumor transplants. Also known as TNF-alpha, it is only 30% homologous to TNF-beta (LYMPHOTOXIN), but they share TNF RECEPTORS.
A secreted member of the TNF receptor superfamily that negatively regulates osteoclastogenesis. It is a soluble decoy receptor of RANK LIGAND that inhibits both CELL DIFFERENTIATION and function of OSTEOCLASTS by inhibiting the interaction between RANK LIGAND and RECEPTOR ACTIVATOR OF NUCLEAR FACTOR-KAPPA B.
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.
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)
Cell Adhesion Molecules
Vascular Cell Adhesion Molecule-1
Cytokine-induced cell adhesion molecule present on activated endothelial cells, tissue macrophages, dendritic cells, bone marrow fibroblasts, myoblasts, and myotubes. It is important for the recruitment of leukocytes to sites of inflammation. (From Pigott & Power, The Adhesion Molecule FactsBook, 1993, p154)
RNA, Small Interfering
Small double-stranded, non-protein coding RNAs (21-31 nucleotides) involved in GENE SILENCING functions, especially RNA INTERFERENCE (RNAi). Endogenously, siRNAs are generated from dsRNAs (RNA, DOUBLE-STRANDED) by the same ribonuclease, Dicer, that generates miRNAs (MICRORNAS). The perfect match of the siRNAs' antisense strand to their target RNAs mediates RNAi by siRNA-guided RNA cleavage. siRNAs fall into different classes including trans-acting siRNA (tasiRNA), repeat-associated RNA (rasiRNA), small-scan RNA (scnRNA), and Piwi protein-interacting RNA (piRNA) and have different specific gene silencing functions.
Receptor Activator of Nuclear Factor-kappa B
A tumor necrosis factor receptor family member that is specific for RANK LIGAND and plays a role in bone homeostasis by regulating osteoclastogenesis. It is also expressed on DENDRITIC CELLS where it plays a role in regulating dendritic cell survival. Signaling by the activated receptor occurs through its association with TNF RECEPTOR-ASSOCIATED FACTORS.
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.)
Filamentous proteins that are the main constituent of the thin filaments of muscle fibers. The filaments (known also as filamentous or F-actin) can be dissociated into their globular subunits; each subunit is composed of a single polypeptide 375 amino acids long. This is known as globular or G-actin. In conjunction with MYOSINS, actin is responsible for the contraction and relaxation of muscle.
Mice, Inbred NOD
Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.
Green Fluorescent Proteins
Stromal cells mediate retinoid-dependent functions essential for renal development. (1/4669)The essential role of vitamin A and its metabolites, retinoids, in kidney development has been demonstrated in vitamin A deficiency and gene targeting studies. Retinoids signal via nuclear transcription factors belonging to the retinoic acid receptor (RAR) and retinoid X receptor (RXR) families. Inactivation of RARaplpha and RARbeta2 receptors together, but not singly, resulted in renal malformations, suggesting that within a given renal cell type, their concerted function is required for renal morphogenesis. At birth, RARalpha beta2(-) mutants displayed small kidneys, containing few ureteric bud branches, reduced numbers of nephrons and lacking the nephrogenic zone where new nephrons are continuously added. These observations have prompted us to investigate the role of RARalpha and RARbeta2 in renal development in detail. We have found that within the embryonic kidney, RARalpha and RARbeta2 are colocalized in stromal cells, but not in other renal cell types, suggesting that stromal cells mediate retinoid-dependent functions essential for renal development. Analysis of RARalpha beta2(-) mutant kidneys at embryonic stages revealed that nephrons were formed and revealed no changes in the intensity or distribution of molecular markers specific for different metanephric mesenchymal cell types. In contrast the development of the collecting duct system was greatly impaired in RARalpha beta2(-) mutant kidneys. Fewer ureteric bud branches were present, and ureteric bud ends were positioned abnormally, at a distance from the renal capsule. Analysis of genes important for ureteric bud morphogenesis revealed that the proto-oncogene c-ret was downregulated. Our results suggest that RARalpha and RARbeta2 are required for generating stromal cell signals that maintain c-ret expression in the embryonic kidney. Since c-ret signaling is required for ureteric bud morphogenesis, loss of c-ret expression is a likely cause of impaired ureteric bud branching in RARalpha beta2(-) mutants. (+info)
Establishment and characterization of nurse cell-like stromal cell lines from synovial tissues of patients with rheumatoid arthritis. (2/4669)OBJECTIVE: To investigate the features of synovial stromal cells established from patients with rheumatoid arthritis (RA), and to define these cells as nurse cells. METHODS: Synovial nurse-like stromal cell lines (RA-SNCs) were established from patients with RA. These cell lines were examined for morphology, pseudoemperipolesis activity, cell surface markers, and cytokine production. The interaction between these RA-SNCs and a synovial tissue B cell clone was also examined. RESULTS: RA-SNCs had nurse cell activity. They spontaneously produced interleukin-6 (IL-6), IL-8, granulocyte colony-stimulating factor, and granulocyte-macrophage colony-stimulating factor. Furthermore, they produced IL-1beta and tumor necrosis factor alpha and expressed higher levels of the other cytokines after coculture with the B cell clone. Proliferation and Ig production by the B cell clone were dependent on direct contact with RA-SNCs. CONCLUSION: These results indicate that the RA-SNCs were nurse cells. The findings suggest that RA-SNCs may play an important role in the pathogenesis of RA by producing large amounts of cytokines and maintaining infiltrating lymphocytes. (+info)
Expression of neurotrophins and their receptors in human bone marrow. (3/4669)The expression of neurotrophins and their receptors, the low-affinity nerve growth factor receptor (p75LNGFR) and the Trk receptors (TrkA, TrkB, and TrkC), was investigated in human bone marrow from 16 weeks fetal age to adulthood. Using reverse transcription-polymerase chain reaction, all transcripts encoding for catalytic and truncated human TrkB or TrkC receptors were detected together with trkAI transcripts, whereas trkAII transcripts were found only in control nerve tissues. Transcripts for the homologue of the rat truncated TrkC(ic113) receptor were identified for the first time in human tissue. Stromal adventitial reticular cells were found immunoreactive for all neutrophin receptors. In contrast, hematopoietic cell types were not immunoreactive for p75LNGFR but showed immunoreactivity for one or several Trk receptors. TrkA immunoreactivity was found in immature erythroblasts. Catalytic TrkB immunoreactivity was observed in eosinophilic metamyelocytes and polymorphonuclear cells. Truncated TrkB immunoreactivity was found in erythroblasts and megacaryocytes. Immunoreactivity for both catalytic and truncated TrkC receptor was observed in promyelocytes, myelocytes, some polymorphonuclear cells and megacaryocytes. Neutrophin transcript levels appeared higher at fetal than at adult stages, no variation in Trk family transcript levels was observed. The local expression of neurotrophin genes suggests a wide range of paracrine and/or autocrine mode of action through their corresponding receptors within the bone marrow. (+info)
Marker molecules of human endometrial differentiation can be hormonally regulated under in-vitro conditions as in-vivo. (4/4669)An established cell culture system of isolated human endometrial stromal and epithelial cells has been used to study the effects of oestrogen and progesterone, as well as their antagonists, upon endometrial cells. Normal hormonal regulation in vivo was investigated simultaneously in endometrial tissue samples taken at different phases of the menstrual cycle. Several marker molecules analysed by immunohistochemistry appeared to depend strongly on endocrine regulation and could be traced in culture. Immunohistochemically, basic parameters of cell biology were identified in vitro, e.g. cell proliferation (Ki-67), adhesion molecules (beta3 integrin) and paracrine factors (leukaemia inhibitory factor). The most reliable parameters to assess hormonal influences were oestrogen and progesterone receptor molecules. Immunohistochemical localization could be improved by molecular biological analysis using RT-PCR. In the presence of oestrogen, a significant expression of hormone receptors was also shown by RT-PCR, and withdrawal of oestrogens and addition of gestagen, i.e. medroxyprogesterone acetate, caused receptor downregulation. Addition of the anti-oestrogen ICI 182.780 to cell-culture medium significantly decreased the synthesis of progesterone receptors. (+info)
Expression of the oxytocin receptor in relation to steroid receptors in the uterus of a primate model, the marmoset monkey. (5/4669)The dynamics of the receptors for oestrogen (ER), progesterone (PR) and oxytocin (OTR) in the marmoset uterus have been analysed throughout the entire cycle and early pregnancy. Uteri obtained during the early, mid/late and late proliferative phase, and the early, mid and late secretory phase and early pregnancy were examined by immunohistochemistry (OTR, ER, PR) and autoradiography (OTR). A massive upregulation of the ER in the cell nuclei of glandular epithelium and stromal cells during the mid proliferative phase was succeeded by a declining staining intensity and positively stained cell number in the secretory phase. PR immunoreactivity increased in the late proliferative phase and early secretory phase, mainly within the cell nuclei, and then declined in both intensity and cell number towards the mid to late secretory phase. Myometrium showed a similar staining pattern for the steroid receptors. OTR were expressed weakly in stroma throughout the entire cycle, increasing slightly in the secretory phase. Glandular epithelium showed positive staining only during the periovulatory period. Myometrial OTR expression was weak during the proliferative phase, increased towards the secretory phase, and was maximal in the late secretory phase. Myometrial tissue adjacent to endometrium was most strongly stained. A cyclic shift evidently occurred in the pattern of steroid receptors, perhaps reflecting the steroid environment or the luteinizing hormone increase associated with ovulation. (+info)
Detection of Kaposi's sarcoma herpesvirus DNA sequences in multiple myeloma bone marrow stromal cells. (6/4669)Whether Kaposi's sarcoma herpesvirus (KSHV) is associated with multiple myeloma (MM) remains controversial. We assayed for KSHV DNA sequences in long-term bone marrow stromal cells (BMSCs) from 26 patients with MM and 4 normal donors. Polymerase chain reaction (PCR) using primers which amplify a KSHV gene sequence to yield a 233-bp fragment (KS330233 within open reading frame 26) was negative in all cases. Aliquots of these PCR products were used as templates in subsequent nested PCR, with primers that amplify a 186-bp product internal to KS330233. BMSCs from 24 of 26 (92%) patients with MM and 1 of 4 normal donors were KSHV PCR+. DNA sequence analyses showed interpatient specific mutations (2 to 3 bp). Both Southern blot and sequence analyses confirmed the specificity of PCR results. The presence of the KSHV gene sequences was further confirmed by amplifying T 1.1 (open reading frame [ORF] K7) and viral cyclin D (ORF 72), two other domains within the KSHV genome. Immunohistochemical studies of KSHV PCR+ MM BMSCs demonstrate expression of dendritic cell (DC) lineage markers (CD68, CD83, and fascin). Serological studies for the presence of KSHV lytic or latent antibodies were performed using sera from 53 MM patients, 12 normal donors, and 5 human immunodeficiency virus (HIV)/KSHV+ patients. No lytic or latent antibodies were present in sera from either MM patients or normal donors. Taken together, these findings show that KSHV DNA sequences are detectable in BMSCs from the majority of MM patients, but that serologic responses to KSHV are not present. Ongoing studies are defining whether the lack of antibody response is caused by the absence of ongoing infection, the presence of a novel viral strain associated with MM, or underlying immunodeficiency in these patients.

In vitro hematopoietic and endothelial cell development from cells expressing TEK receptor in murine aorta-gonad-mesonephros region. (7/4669)Recent studies have shown that long-term repopulating hematopoietic stem cells (HSCs) first appear in the aorta-gonad-mesonephros (AGM) region. Our immunohistochemistry study showed that TEK+ cells existed in the AGM region. Approximately 5% of AGM cells were TEK+, and most of these were CD34(+) and c-Kit+. We then established a coculture system of AGM cells using a stromal cell line, OP9, which is deficient in macrophage colony-stimulating factor (M-CSF). With this system, we showed that AGM cells at 10.5 days postcoitum (dpc) differentiated and proliferated into both hematopoietic and endothelial cells. Proliferating hematopoietic cells contained a significant number of colony-forming cells in culture (CFU-C) and in spleen (CFU-S). Among primary AGM cells at 10.5 dpc, sorted TEK+ AGM cells generated hematopoietic cells and platelet endothelial cell adhesion molecule (PECAM)-1(+) endothelial cells on the OP9 stromal layer, while TEK- cells did not. When a ligand for TEK, angiopoietin-1, was added to the single-cell culture of AGM, endothelial cell growth was detected in the wells where hematopoietic colonies grew. Although the incidence was still low (1/135), we showed that single TEK+ cells generated hematopoietic cells and endothelial cells simultaneously, using a single-cell deposition system. This in vitro coculture system shows that the TEK+ fraction of primary AGM cells is a candidate for hemangioblasts, which can differentiate into both hematopoietic cells and endothelial cells.

A novel stromal cell-dependent B lymphoid stem-like cell line that induces immunoglobulin gene rearrangement. (8/4669)A stroma-dependent B lymphoid cell line (B31-1) has been established by coculturing sorted stem cells on a novel bone marrow stromal cell line (TBR31-1). B31-1 cells express B220, but do not express other B lymphoid differentiation markers including CD43, heat stable antigen (HSA), or surface immunoglobulin (Ig) M (sIgM), and their Ig heavy chain (IgH) gene loci are germ-line in configuration. The addition of interleukin (IL)-7 or coculture with another stromal cell line, ST2, induces D-J rearrangement of the IgH gene and B lymphocyte differentiation markers. B31-1 cells restore an in vivo repopulation activity to lethally irradiated mice, and the repopulated cells differentiate to HSA+ pre-B cells.Continuous coculture results in two distinct populations, B220(-) c-Kit+ cells and B220(+) c-Kit+ cells; B220(-) c-Kit+ cells are self-renewed and differentiate to B220(+) c-Kit+ cells, while B220(+) c-Kit+ cells produce only B220(+) c-Kit+ cells. Both B220(-) and B220(+) cells similarly express the IgH germ-line transcript (Imu), mRNAs for recombinase (TdT, Rag-1, and Rag-2), and lymphoid-specific transcription factors (Pax-5, EBF, E12/E47, Oct-2, and Ikaros), but the DNA binding activity of Pax-5, EBF, Oct-2, and E2A are low in B220(-) cells and while high in B220(+) cells. These results suggest the existence of at least two active states in the IgH locus before the induction of IgH gene rearrangement during B lymphopoietic development. (+info)

N2 - Adipose tissue-derived stromal cells (ASCs) are increasingly being studied for their usefulness in regenerative medicine. However, limited life span and donor-dependent variation of primary cells such as ASCs present major hurdles to controlled and reproducible experiments. We therefore aimed to establish immortalized ASC cell lines that provide steady supply of homogeneous cells for in vitro work while retain essential features of primary cells. To this end, combinations of human telomerase reverse transcriptase (hTERT), murine Bmi-1, and SV40 large T antigen (SV40T) were introduced by lentiviral transduction into ASCs. The resulting cell lines ASC ...

TY - JOUR. T1 - Adipose stromal cells differentiation toward smooth muscle cell phenotype diminishes their vasculogenic activity due to induction of activin A secretion. AU - Merfeld-Clauss, Stephanie. AU - Lease, Benjamin R.. AU - Lu, Hongyan. AU - March, Keith L.. AU - Traktuev, Dmitry O.. PY - 2017/11. Y1 - 2017/11. N2 - Adipose stromal cells (ASCs) support endothelial cell (EC) vasculogenesis through paracrine and cell-contact communications. In addition, ASCs differentiate towards the smooth muscle cell (SMC) phenotype under different stimuli, which prompted their use as a source of mural cells in fabricating small calibre vessels. How ASCs SMC-lineage commitment affects their subsequent communication with ECs is unknown. The vasculogenic characteristics of human ASCs in progenitor stage and after differentiation towards SMC phenotype were analysed in the present study. Exposure to transforming growth factor β1 (TGFβ1) or activin A has induced expression of SMC markers in ASCs. Analysis ...

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 ...

Screening differentially expressed proteins from co-cultured hematopoietic cells and bone marrow-derived stromal cells by...
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,
USE OF ADIPOSE-DERIVED PREADIPOCYTES IN BONE DISOREDERS | SBIR.gov
Non-healing bone fractures and periodontal bone loss constitute significant clinical problems with few approved medical options. Bone repair is enhanced by the presence of osteoblasts or osteoblastic precursor cells. Subcutaneous adipose tissue is a plentiful, accessible, and replenishable source of human stromal cells for transplantation. In Phase I of this SBIR, we tested the hypothesis that human adipose tissue-derived stromal cells are capable of osteoblast function. Substantial in vitro data indicates that these stromal cells differentiate into cells biochemically and morphologically similar to osteoblasts. The ability of these cells to form bone in vivo was examined as well. Phase II of this SBIR will extend these in vivo experiments. Specific Aim 1 examines the ability of human adipose tissue-derived stromal cells to form ectopic bone in hydroxyapatite ceramic cubes implanted subcutaneously in immunodeficient mice. Specific Aim 2 explores whether the introduction of a modified bone ...

Epidermal Growth Factor and Transforming Growth Factor-α Stimulate the Proliferation of Mouse Uterine Stromal Cells - OKAYAMA...
Growth factors produced in the uterine endometrium are considered to be involved in the proliferation of the mouse uterine stromal cells induced by estradiol-17beta (E-2) and progesterone (P). The effect of epidermal growth factor (EGF) and transforming growth factor-alpha (TGF-alpha), one of EGF-related growth factors, on the proliferation of mouse uterine stromal cells was studied in a serum-free culture. The growth of the uterine stromal cells was measured by MTT assay. EGF was found to increase the number of uterine stromal cells in a dose-dependent manner. The DNA-replicating cells were investigated using the immunocytochemical detection of bromodeoxyuridine (BrdU)-labeled cells. EGF and TGF-alpha increased the percentage of BrdU-Iabeled cells in a dose-dependent manner. Administration of the combination of E-2 (10(-9) M) and P (10(-7) M) for 2 days increased the percentage of BrdU-Iabeled cells 2.3-fold. The stimulatory effect of EGF, TGF-a and the combination of E2 and P on DNA ...

In this study, we analyzed the influence of mesenchymal stromal cells derived from lymph nodes of non-Hodgkin lymphomas, on effector functions and differentiation of Vδ2 T lymphocytes. We show that: i) lymph-node mesenchymal stromal cells of non-Hodgkin lymphoma inhibit NKG2D-mediated lymphoid cell killing, but not rituximab-induced antibody-dependent cell-mediated cytotoxicity, exerted by Vδ2 T lymphocytes; ii) pre-treatment of mesenchymal stromal cells with the aminobisphosphonates pamidronate or zoledronate can rescue lymphoma cell killing via NKG2D; iii) this is due to inhibition of transforming growth factor-β and increase in interleukin-15 production by mesenchymal stromal cells; iv) aminobiphosphonate-treated mesenchymal stromal cells drive Vδ2 T lymphocyte differentiation into effector memory T cells, expressing the Thelper1 cytokines tumor necrosis factor-α and interferon-γ. In non-Hodgkin lymphoma lymph-nodes, Vδ2 T cells were mostly naive; upon co-culture with autologous ...
In this study, the role of histamine in interleukin-1 (IL-1) formation in murine bone marrow stromal cells was investigated in vitro. It was found that histamine and 4-methylhistamine increased the number of granulocyte colony-forming units in murine bone marrow cells. A similar effect was elicited by dibutyryl-cAMP and theophylline. When histamine and H2 agonists, such as 4-methylhistamine and dimaprit, were added to the culture medium containing murine bone marrow stromal cells, thymocyte comitogenic activity detected in the medium increased significantly. However, no such effect was observed in the case of 2-methyl-histamine, an H1 agonist. Histamine-induced production of thymocyte comitogenic activity in bone marrow stromal cells was inhibited by some H2 antagonists, such as cimetidine, ranitidine, and famotidine, but not by the H1 antagonist pyrilamine. Histamine was also effective in inducing the colony-promoting activity in murine bone marrow stromal cells. This was also inhibited by H2 ...
Paper: Characterization of Human Bone Marrow Stromal Cells During Multi-passaging (AADR Annual Meeting (March 21-24, 2012))
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. ...
Synthesis of calbindin-D28K during mineralization in human bone marrow stromal cells | Biochemical Journal
1α,25-Dihydroxyvitamin D3 [1,25(OH)2D3] is known to modulate Ca2+ metabolism in several cell types. Vitamin-D-dependent calcium binding proteins such as calbindin-D28K (28 kDa calcium binding proteins) have been shown to be regulated by 1,25(OH)2D3 but the mechanisms controlling calbindin synthesis are still poorly understood in human osteoblast cell culture models. The human bone marrow stromal cells (HBMSC) described in this paper developed a calcified matrix, expressed osteocalcin (OC), osteopontin (OP) and responded to 1,25(OH)2D3. The expression of vitamin D receptor mRNA was demonstrated by reverse transcription-PCR. Calbindin-D28K protein was identified only in cells arising from the sixth subculture, which exhibited a calcified matrix and all of the osteoblastic markers, e.g. OC and OP. It was demonstrated by dot-immunodetection using immunological probes, and by in situ hybridization using labelled cDNA probes. Moreover, vitamin D3 enhanced calbindin-D28K synthesis as well as OC ...
Impaired lymph node stromal cell function during the earliest phases of rheumatoid arthritis | Arthritis Research & Therapy |...
Systemic autoimmunity can be present years before clinical onset of rheumatoid arthritis (RA). Adaptive immunity is initiated in lymphoid tissue where lymph node stromal cells (LNSCs) regulate immune responses through their intimate connection with leucocytes. We postulate that malfunctioning of LNSCs creates a microenvironment in which normal immune responses are not properly controlled, possibly leading to autoimmune disease. In this study we established an experimental model for studying the functional capacities of human LNSCs during RA development. Twenty-four patients with RA, 23 individuals positive for autoantibodies but without clinical disease (RA risk group) and 14 seronegative healthy control subjects underwent ultrasound-guided inguinal lymph node (LN) biopsy. Human LNSCs were isolated and expanded in vitro for functional analyses. In analogous co-cultures consisting of LNSCs and peripheral blood mononuclear cells, αCD3/αCD28-induced T-cell proliferation was measured using
The Effect of αCT-1 Peptide on Bone Marrow Stromal Cells Following Inj by Adam Clay Vandergriff
Connexin43 (Cx43) is a component of gap junctions and is involved in intercel- lular signaling following injury to tissues. The carboxyl terminus of Cx43 binds to the PDZ2 domain of ZO-1 in order to form gap junction plaques and connect to the cytoskeleton. A biomimetic peptide known as αCT-1, replicating the last 9 amino acids found in the carboxyl terminus of CX43, has been shown to improve wound healing by preferentially binding to the PDZ2 domain of ZO-1. A possible mecha- nism for its action is through the Epithelial-Mesenchymal Transformation (EMT). Scratch assays were performed on rat bone marrow stromal cells treated with the peptide and were then analyzed using qPCR, western blotting, confocal microscopy, and live cell imaging. The gene expression analysis showed up-regulation of F11r and Krt19 and down-regulation of Mmp3. Protein expression analysis indicated an increase in Krt19 and the complete absence of Snai2 in the αCT-1 treated samples. Confocal microscopy suggested increased actin
Reciprocal Interactions of Leukemic Cells with Bone Marrow Stromal Cells Promote Enrichment of Leukemic Stem Cell Compartments...
A predominant challenge in developing curative leukemia therapy is interactions of leukemic cells with the bone marrow stromal microenvironment. We aimed to investigate the role of stromal cells, such as bone marrow mesenchymal stromal cells (BMSCs) and osteoblasts (OBs), in curcumin (CUR) and daunorubicin (DNR) induced apoptosis of acute myeloid leukemia (AML) cells. We used KG1 and U937 as leukemia cell line models and treated them with CUR and DNR. The cells were then co-cultured with BMSCs or a combination of BMSCs and OBs as feeders. After 24 hours of co-culture, BMSCs or OBs were sorted and separated from the leukemia cells and apoptosis levels were analyzed by annexin/propidium iodide (PI) staining on flow cytometry. Potentially involved molecular pathways were analyzed at gene and protein levels by Real time PCR and western blotting, respectively. The results showed AML cells co-cultured with BMSCs plus OBs to be more resistant to drug induced-apoptosis compared to co-culture with BMSCs alone

Stromal Cells in Immunity and Disease 20Q5 - Summary
Non-hematopoietic stromal cells play important roles in many tissues, constructing tissue microenvironments, contributing to tissue repair, defense and immune responses. Within lymphoid organs, stromal cells organize and interact with leukocytes in an immunologically important manner. In addition to organizing T and B cell segregation and expressing lymphocyte survival factors, stromal cells support the migration and interactions between antigen presenting cells and naïve T and B cells during the initiation of immune responses and influence the outcome between tolerance and immunity. Stromal cells also play instrumental roles in coordinating immune responses in non-lymphoid tissues, in inflammatory and autoimmune diseases, and in chronic infection. For instance, stromal cell dysregulation has been seen in HIV infection and in cancer patients. Furthermore, stromal cells are being harnessed for therapeutic applications in several diseases, an area that holds great promise for improving human ...
Leukemia cells induce changes in human bone marrow stromal cells | Journal of Translational Medicine | Full Text
Bone marrow stromal cells (BMSCs) are multipotent cells that support angiogenesis, wound healing, and immunomodulation. In the hematopoietic niche, they nurture hematopoietic cells, leukemia, tumors and metastasis. BMSCs secrete of a wide range of cytokines, growth factors and matrix proteins which contribute to the pro-tumorigenic marrow microenvironment. The inflammatory cytokines IFN-γ and TNF-α change the BMSC secretome and we hypothesized that factors produced by tumors or leukemia would also affect the BMSC secretome and investigated the interaction of leukemia cells with BMSCs. BMSCs from healthy subjects were co-cultured with three myeloid leukemia cell lines (TF-1, TF-1α and K562) using a trans-well system. Following co-culture, the BMSCs and leukemia cells were analyzed by global gene expression analysis and culture supernatants were analyzed for protein expression. As a control, CD34+ cells were also cocultured with BMSCs. Co-culture induced leukemia cell gene expression changes in stem
Adipose tissue-derived stromal vascular fraction in regenerative medicine: a brief review on biology and translation | Stem...
Adipose/fat tissue provides an abundant source of stromal vascular fraction (SVF) cells for immediate administration and can also give rise to a substantial number of cultured, multipotent adipose-derived stromal cells (ADSCs). Recently, both SVF and ADSCs have gained wide-ranging translational significance in regenerative medicine. Initially used for cosmetic breast enhancement, this mode of treatment has found use in many diseases involving immune disorders, tissue degeneration, and ischaemic conditions. In this review, we try to address several important aspects of this field, outlining the biology, technology, translation, and challenges related to SVF- and ADSC-based therapies. Starting from the basics of SVF and ADSC isolation, we touch upon recently developed technologies, addressing elements of novel methods and devices under development for point-of-care isolation of SVF. Characterisation of SVF cells and ADSCs is also an evolving area and we look into unusual expression of CD34 antigen as an
TNFα and IL1β Stimulate Dif-ferential Gene Expression in Endometrial Stromal Cells
The purpose of this study was to test the hypothesis that specific macrophage-secreted cytokines cause gene expression changes in endometrial stromal cells that reproduce the effects of macro-phages in the development of endometriosis. Telomerase-immortalized human endometrial stromal cells (T-HESC) were treated with tumor necrosis factor α (TNFα, 5 ng/ml) and interleukin 1β (IL1β, 1 ng/ml). Differential expression of 249 genes was identified by DNA microarray. Ontologies such as peptidases, cell adhesion, cell death/cell cycle, growth factors, cytoskeletal organization, defense/immune system, signal transduction, and transcriptional regulation which are related to the development of endometriosis were represented by these genes. The up-regulation of interleukin 8 (IL8), interleukin 6 (IL6), IL1β and matrix metallopro-teinase 3 (MMP3) in response to TNFα ± ILIβ in T-HESC cells was confirmed by real time RT-PCR. TNFα ± ILIβ did not affect the migration or invasion of T-HESC cells. This study

Among stromal cells, ...
Stromal cell - Wikipedia
Stromal cells are connective tissue cells of any organ, for example in the uterine mucosa (endometrium), prostate, bone marrow, lymph node and the ovary. They are cells that support the function of the parenchymal cells of that organ. Fibroblasts and pericytes are among the most common types of stromal cells. The interaction between stromal cells and tumor cells is known to play a major role in cancer growth and progression. In addition, by regulating local cytokine networks (e.g. M-CSF, LIF), bone marrow stromal cells have been described to be involved in human haematopoiesis and inflammatory processes. Stromal cells (in the dermis layer) adjacent to the epidermis (the very top layer of the skin) release growth factors that promote cell division. This keeps the epidermis regenerating from the bottom while the top layer of cells on the epidermis are constantly being sloughed off the body. Certain types of skin cancers (basal cell carcinomas) cannot spread throughout the body because the cancer ...

Aging | Molecular basis of senescence transmitting in the population of human endometrial stromal cells - Figure
Hormone-regulated proliferation and differentiation of endometrial stromal cells (ESCs) determine overall endometrial plasticity and receptivity to embryos. Previously we revealed that ESCs may undergo premature senescence, accompanied by proliferation loss and various intracellular alterations. Here we focused on whether and how senescence may be transmitted within the ESCs population. We revealed that senescent ESCs may induce paracrine senescence in young counterparts via cell contacts, secreted factors and extracellular vesicles. According to secretome-wide profiling we identified plasminogen activator inhibitor -1 (PAI-1) to be the most prominent protein secreted by senescent ESCs (data are available via ProteomeXchange with identifier PXD015742). By applying CRISPR/Cas9 techniques we disclosed that PAI-1 secreted by senescent ESCs may serve as the master-regulator of paracrine senescence progression within the ESCs population.

In vivo gene manipulation reveals the impact of stress-responsive MAPK pathways on tumor progression - Semantic Scholar
It has been widely accepted that tumor cells and normal stromal cells in the host environment coordinately modulate tumor progression. Mitogen-activated protein kinase pathways are the representative stress-responsive cascades that exert proper cellular responses to divergent environmental stimuli. Genetically engineered mouse models and chemically induced tumorigenesis models have revealed that components of the MAPK pathway not only regulate the behavior of tumor cells themselves but also that of surrounding normal stromal cells in the host environment during cancer pathogenesis. The individual functions of MAPK pathway components in tumor initiation and progression vary depending on the stimuli and the stromal cell types involved in tumor progression, in addition to the molecular isoforms of the components and the origins of the tumor. Recent studies have indicated that MAPK pathway components synergize with environmental factors (e.g. tobacco smoke and diet) to affect tumor initiation and

Requirement for VLA-4 and VLA-5 integrins in lymphoma cells binding to and migration beneath stromal cells in culture. | JCB
Physical interaction between human lymphomas and murine bone marrow derived stromal cells were studied. Nalm-6 pre-B cells adhered to BMS2 stromal cells and subsequently migrated beneath them, while Ramos Burkitt lymphoma cells, adhered but did not migrate. Four mAbs were established against Nalm-6 cells, which were able to block initial adhesion of Nalm-6 cells. Two of them were directed against the alpha 4 chain of VLA-4, and other two recognized the beta 1 chain of VLA integrins. Therefore, the initial adhesion of Ramos and Nalm-6 cells to BMS2 was largely mediated by the VLA-4 integrin expressed on lymphocytes. The corresponding ligand on stromal cells appears to be VCAM-1, because antibodies against murine VCAM-1 blocked the adhesion. However, antibodies against the alpha chain of VLA-4 were not capable of blocking subsequent migration beneath stromal cells. In contrast, antibodies against the beta chain of VLA integrins blocked the migration beneath stromal cells as well as the initial ...

N2 - Tissue resident mesenchymal stromal cells (MSCs) contribute to tissue regeneration through various mechanisms, including the secretion of trophic factors that act directly on epithelial stem cells to promote epithelialization. However, MSCs in tissues constitute a heterogeneous population of stromal cells and different subtypes may have different functions. In this study we show that CD166neg and CD166pos lung stromal cells have different proliferative and differentiative potential. CD166neg lung stromal cells exhibit high proliferative potential with the capacity to differentiate along the lipofibroblastic and myofibroblastic lineages, whereas ...
OP0258 IL-22 Regulates Lymphoid Stromal Cell Expansion, Development of Germinal Centers and Humoral Response in Mucosal Ectopic...
Results WT mice stromal cells display early acquisition of lymphoid features, up-regulating gp38 already at 3hours pc. Peak of this activation was observed at day5 with significant increase in the percentage of gp38+ lymphoid like stromal cells (LLSc), this increase is maintained between day8-15 pc. However, full acquisition of lymphoid phenotype, indicated by high levels of lymphoid CKs/cytokine expression was observed by day8-15 pc. This correlates with full maturation of the lymphoid aggregates in terms of T/B cell segregation and FDC formation. Of interest, RAG and LTbR KO mice showed normal degree of stromal cell activation in the early phases (2-5days p.c.) but a dramatic decrease in the percentage of LLSc by day15. However, these KOs exhibited a defect in full lymphoid conversion of stromal cells shown by significant decrease in CKs/cytokine expression and aggregates disorganization, suggesting that the full maturation of stromal cells require lymphocyte-derived signals such as ...
The interferon-inducible protein p202 promotes osteogenesis in mouse bone marrow stromal cells | Bioscience Reports | Portland...
Finally, the mechanism by which p202 activates BMSC osteogenesis was determined. Runx2 is a critical transcription factor in osteogenesis. Previous study has detected the association of p204 with Runx2 . However, in the present study, no interaction of p202 with Runx2 was seen (Figure 5C). p202 may lack an interacting structure with Runx2 protein. Id proteins are important suppressors in the differentiation of many cell types [13,20,21]. We found that Id proteins not only bound to Runx2, but also associated with p202 in the course of BMSC osteogenesis, and Id2 was a major associated family member (Figure 5A,B). It is possible that p202 disturbs the formation of Runx2/Ids complex and frees Runx2 to induce the differentiation process. Subsequent investigation demonstrated that this is the case. SiRNA-p202 dramatically lowered the p202-bound Id2, while enhanced the Runx2-associated Id2 content significantly. However, p202 overexpression increased the p202-bound Id2, but decreased the ...
Endothelial cells influence the osteogenic potential of bone marrow stromal cells
Background: Improved understanding of the interactions between bone cells and endothelial cells involved in osteogenesis should aid the development of new strategies for bone tissue engineering. The aim of the present study was to determine whether direct communication between bone marrow stromal cells (MSC) and human umbilical vein endothelial cells (EC) could influence the osteogenic potential of MSC in osteogenic factor-free medium. Methods: After adding EC to MSC in a direct-contact system, cell viability and morphology were investigated with the WST assay and immnostaining. The effects on osteogenic differentiation of adding EC to MSC was systematically tested by the using Superarray assay and results were confirmed with real-time PCR. Results: Five days after the addition of EC to MSC in a ratio of 1:5 (EC/MSC) significant increases in cell proliferation and cellular bridges between the two cell types were detected, as well as increased mRNA expression of alkaline phosphatase (ALP). This ...
Isolation, Culture, and Differentiation of Bone Marrow Stromal Cells a by David E Maridas, Elizabeth Rendina-Ruedy et al.
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

NCHU Institutional Repository CRIS: Transplantation of bone marrow stromal cells for peripheral nerve repair
Cell transplantation using bone marrow stromal cells (BMSCs) to alleviate neurological deficits has recently become the focus of research in regenerative medicine. Evidence suggests that secretion of various growth-promoting substances likely plays an important role in functional recovery against neurological diseases. In an attempt to identify a possible mechanism underlying the regenerative potential of BMSCs, this study investigated the production and possible contribution of neurotrophic factors by transected sciatic nerve defect in a rat model with a 15 mm gap. Cultured BMSCs became morphologically homogeneous with fibroblast-like shape after ex vivo expansion. We provided several pieces of evidence for the beneficial effects of implanted fibroblast-like BMSCs on sciatic nerve regeneration. When compared to silicone tube control animals, this treatment led to (i) improved walking behavior as measured by footprint analysis, (ii) reduced loss of gastrocnemius muscle weight and EMG magnitude, ...
Interleukin 7 independent development of human B cells | PNAS
Mammalian hematopoietic stem cell (HSC) commitment and differentiation into lymphoid lineage cells proceed through a series of developmentally restricted progenitor compartments. A complete understanding of this process, and how it differs from HSC commitment and differentiation into cells of the myeloid/erythroid lineages, requires the development of model systems that support HSC commitment to the lymphoid lineages. We now describe a human bone marrow stromal cell culture that preferentially supports commitment and differentiation of human HSC to CD19+ B-lineage cells. Fluorescence activated cell sorterpurified CD34++/lineage-cells were isolated from fetal bone marrow and cultured on human fetal bone marrow stromal cells in serum-free conditions containing no exogenous cytokines. Over a period of 3 weeks, CD34++/lineage- cells underwent commitment, differentiation, and expansion into the B lineage. Progressive changes included: loss of CD34, acquisition of and graded increases in the level of ...
Surface epithelial-stromal tumor - wikidoc
Surface epithelial-stromal tumors are a class of ovarian neoplasms that may be benign or malignant. Neoplasms in this group are thought to be derived from the ovarian surface epithelium (modified peritoneum) or from ectopic endometrial or Fallopian tube (tubal) tissue. This group of tumors accounts for 90% to 95% of all cases of ovarian cancer. The pathogenesis of surface epithelial-stromal tumor is characterized by the overgrowth of the ovarian surface epithelium. Common risk factors in the development of surface epithelial-stromal tumor, include: nulliparity, early menopause, gonadal dysgenesis, family history (e.g. BRCA1/BRCA2 mutations), smoking, previous history of breast, and endometrial or colon cancer (Lynch II). The prevalence of surface epithelial-stromal tumor is approximately 3 per 100,000 individuals worldwide. Surface epithelial-stromal tumor is more commonly observed among postmenopausal women. Early clinical features of surface epithelial-stromal tumor include pelvic ...
PSRC - RESTORATION OF LONG NERVE DEFECTS WITH EPINEURAL SHEATH CONDUIT SUPPORTED WITH BONE MARROW STROMAL CELLS. A PRELIMINARY...
Cleveland Clinic Background: Nerve gaps that need conduit or allograft material tend to involve regional loss of overlying soft tissues and muscles spanning a gap of over 20 cm. Currently used autograft technique requires immunosuppression and demonstrated poor motor recovery.. Main goals: We developed epineural sheath conduit supported with bone marrow stromal cells (BMSCs) to restore 6 cm nerve defects. Epineural sheath is immunologically neutral and contains laminin, enhancing neuronal growth. Addition of BMSCs will contribute to structural support and secretion of growth factors for nerve regeneration.. Methods: Sheep model was used since sheep peripheral nerves are histologically and morphometrically similar to human nerves. Epineural sheath tube was created from the median nerve by the pull out technique, removing all fascicles. BMSCs were obtained from donor animal, purified by the buffy coat technique and cultured for 14 days. Next, cells were fluorescently labeled and injected into the ...
IGFBP7, a novel tumor stroma marker, with growth-promoting effects in colon cancer through a paracrine tumor-stroma interaction...
The activated tumor stroma participates in many processes that control tumorigenesis, including tumor cell growth, invasion and metastasis. Cancer-associated fibroblasts (CAFs) represent the major cellular component of the stroma and are the main source for connective tissue components of the extracellular matrix and various classes of proteolytic enzymes. The signaling pathways involved in the interactions between tumor and stromal cells and the molecular characteristics that distinguish normal resting fibroblasts from cancer-associated or -activated fibroblasts remain poorly defined. Recent studies emphasized the prognostic and therapeutic significance of CAF-related molecular signatures and a number of those genes have been shown to serve as putative therapeutic targets. We have used immuno-laser capture microdissection and whole-genome Affymetrix GeneChip analysis to obtain transcriptional signatures from the activated tumor stroma of colon carcinomas that were compared with normal resting

Frontiers | Alteration of the antitumor immune response by cancer-associated fibroblasts | Immunology
Among cells present in the tumor microenvironment, activated fibroblasts termed cancer-associated fibroblasts (CAFs), play a critical role in the complex process of tumor-stroma interaction. CAFs, one of the prominent stromal cell populations in most types of human carcinomas, have been involved in tumor growth, angiogenesis, cancer stemness, extracellular matrix remodeling, tissue invasion, metastasis and even chemoresistance. During the past decade, these activated tumor-associated fibroblasts have also been involved in the modulation of the anti-tumor immune response on various levels. In this review, we describe our current understanding of how CAFs accomplish this task as well as their potential therapeutic implications.
