conclusions although the aforementioned challenges must still be addressed, the potential of wjmscs in skin regenerative clinical treatments is promising. results similar to bone marrow mscs, wjmscs express major histocompatibility complex (mhc) class i molecules. evidence acquisition according to research conducted by various researchers, wharton’s jelly mesenchymal stem cells (wjmscs) have se...

Introduction: Bone marrow (BM) is a known source of mesenchymal stem cells (MSCs) that are used for cell therapy. This study attempts to identify if the Wharton’s Jelly (WJ) is a suitable substitute for BM as a source for MSCs. Materials and Methods: A population of human WJ and BM stem cells were isolated and incubated with fluorescein conjugated antibodies for five specific MSC markers....

Abstract Although multiple studies have investigated the mesenchymal stem and progenitor cells (MSCs) that give rise to mature bone marrow, high heterogeneity in their morphologies properties causes difficulties molecular separation of distinct populations. In this study, by taking advantage resolution single cell transcriptome, we analyzed Sca-1 PDGFR-? fraction mouse marrow tissue. The transc...

osteoarthritis (oa) is a prevalent chronic disease impacting on quality of life and has societal and economical burden increasing with age. yet, no confirmed pharmacological, biological or surgical therapy could prevent the progressive destruction of oa joint. mesenchymal stem cells (mscs) with immunosuppressive activities emerged a potential therapy. we describe a magnetic resonance images (mr...

The viability of cryopreserved mouse fresh and postmortem bone marrow cells was studied using methylcellulose clonal cell culture assay and the murine spleen colony technique. This study clearly indicates the presence of pluripotent hemopoietic stem cells in cryopreserved murine postmortem bone marrow cells. The viability of granulocytic precursors in both fresh and postmortem bone marrow cells...

Aplastic anemia is a life-threatening bone marrow failure disorder characterized by peripheral pancytopenia and marrow hypoplasia. The majority of cases of aplastic anemia remain idiopathic, although hematopoietic stem cell deficiency and impaired immune responses are hallmarks underlying the bone marrow failure in this condition. Mesenchymal stem/stromal cells constitute an essential component...

background: bone marrow stromal cells (bmsc) have been successfully employed for movement deficit recovery in spinal cord injury (sci) rat models. one of the unsettled problems in cell transplantation is the relative high proportion of cell death, specifically after neural differentiation. according to our previous studies, p75 receptor, known as the death receptor, is only expressed in bmsc in...

conclusions our findings showed that the treatment of flaps with bm-msc and aam transplantations significantly promoted flap survival compared to a control group. the viability of the flap was improved by combining bm-mscs with aam matrix scaffolds. materials and methods bm-mscs and aams were transplanted into subcutaneous tissue in the flap area. on the 7th postoperative day, the surviving fla...

the relationship between the way in which normal hemopoietic stem cells respond to irradiation alone or in the presence of bleomycin sulfate (blm-s) and actinomycin 0 (act-d) was investigated. single doses of blm-s at 0.3 mg/kg and act-o at 0.10 mg/kg body weight were injected intravenously 1-6 hours prior to whole body irradiation and treatment was repeated twice more with time intervals. when...
