Differentiation of Thymus-derived Cells from Precursors in Mouse Bone Marrow
نویسندگان
چکیده
An experimental model system was developed to study the differentiation of thymus-derived (T) cells from progenitors in bone marrow. In this system transplantation of bone marrow cells depleted of T cells gave rise to T cells in the spleens of irradiated recipients within 15 days of transplantation. Thus, normal bone marrow contains a class of cells that are progeniotrs of T cells (PT cells). PT cells are different from T cells since PT cells are incapable of responding to alloantigen, are theta resistant, and band in a lighter density region than do T cells. The density profile of PT cells is different from that of hematopoietic stem cells (CFU-S); PT cells band in a denser region of the gradient than do CFU-S.

Effects of BIO on proliferation and chondrogenic differentiation of mouse marrow-derived mesenchymal stem cells
In vitro expansion of mesenchymal stem cell (MSCs) into large number is necessary for their application in cell-based treatment of articular cartilage defects. On the other hand, some studies have indicated that BIO (6-Bromoindirubin-3-Oxime) possesses mitogenic effects on cell culture. The objective of the present study was to examine the effect of BIO on in vitro expansion and chondrogenic di...
متن کاملAnalysis of MiRNA-17 and MiRNA-146 Expression During Differentiation of Spermatogonial Stem Like Cells Derived from Mouse Bone Marrow Mesenchymal Stem Cells
In vitro derivation of germ cells from different stem cells sources has been challenging in the treatment of male infertility. MicroRNAs (miRNAs) have an essential role in gene expression at post-transcriptional level. The aim of this research was to find more about miRNA-17 and miRNA-146 expression during differentiation of spermatogonial stem cell like cells (SSC like cells) from mouse bone m...
متن کاملCFU-GM Like Colonies Derived from Embryonic Stem Cells Cultured on the Bone Marrow Stromal Cells
The aim of this study was to isolate mouse embryonic stem cells from late blastocyst stage embryos and to use them as a model system for the study of hematopoietic induction outside the embryo by coculturing of embryonic stem cells with bone marrow stromal cells. Blastocyst stage embryos from pregnant NMRI mice were obtained and cultured for 1-2 days in DMEM medium. The inner cell masses formed...

The ontogeny of mammalian cell-mediated immune responsiveness is critically dependent upon the specialized maturational microenvironment of the thymus . The initial event heralding the lymphoid development of the thymus occurs (in the mouse) at approximately the eleventh day of gestation, when lymphoid stem cells, apparently derived from the yolk sac or fetal liver, migrate into the largely epi...
متن کاملBiological behaviors of muscarinic receptors in mesenchymal stem cells derived from human placenta and bone marrow
Objective(s): Cells perform their functional activities by communicating with each other through endogenous substances and receptors. Post-translation, stem cells function properly in new host tissue by carrying specific cell surface receptors. We aimed to characterize muscarinic receptor subtypes in mesenchymal stem cells (MSCs) together with osteogenic and adipogenic...
متن کاملEvaluation of In Vitro Differentiation of Cardiomyocyte-like cells Derived from Human Bone Marrow Mesenchymal Stem Cells
Purpose: To investigate the in vitro differentiation process of cardiomyocyte-like cells derived from human bone marrow mesenchymal stem cells under the influence of 5-azacytidine (5-aza). Materials and Methods: After purification, human bone marrow mesenchymal stem cells were exposed to 5-aza at a concentration of 5 μmol for 5 weeks to induce cardiomyocyte differentiation. To induce differenti...
