objective(s):sea cucumber derived bioactive compound is considered efficient in treatment of bone disorders. this study was performed to evaluate the effect of this extract on differentiation of rat bone marrow mesenchymal stem cells (rbmmsc) into osteogenic lineage. materials and methods: isolated rbmmsc were grown in dmem supplemented with 10% fbs. the cells were exposed to different concen...
Transplantation of marrow-derived mesenchymal stem cells (MSCs), expanded by culture in addition to whole bone marrow, has been shown to enhance engraftment of human hematopoietic stem cells (HSCs). Our hypothesis was that there might be an optimum ratio range that could enhance engraftment. We examined the percent donor chimerism according to the ratio of HSCs to MSCs in non-obese diabetic/sev...
Mixed hematopoietic chimerism is a state in which bone marrow hematopoietic stem cells from two genetically different animals coexist. We investigated whether mixed hematopoietic chimerism, resulting from the transplantation of host and donor bone marrow into a lethally irradiated rat, would confer donor-specific tolerance to lung allografts. Recipient rats (Fisher or or Wistar Furth [WF]) were...
Interleukin-7 (IL-7) has been shown to enhance thymic output of newly developed T cells following bone marrow transplantation (BMT) in mice. In addition, IL-7 may affect peripheral expansion of T cells. In order to study the relative contribution of thymopoiesis versus peripheral T-cell expansion in the setting of compromised thymopoiesis, we have applied IL-7 in an experimental stem cell trans...
Bone marrow transplantation might be an effective method to cure type 1 diabetes mellitus. This study aimed to investigate whether bone marrow transplantation could reverse hyperglycemia in diabetic mice and whether high-dose total body irradiation followed by high-dose bone marrow mononuclear cell infusion could improve the efficiency of bone marrow transplantation in treating diabetic mice. D...
OBJECTIVES The present study was designed as a face-to-face functional comparison of human skeletal myoblasts (SMs) and CD133(+) bone marrow-derived hematopoietic progenitors in an animal model of semichronic myocardial infarction. BACKGROUND Compared with SMs, bone marrow-derived cells have the advantage of plasticity and might more effectively regenerate ischemic cardiac tissue. However, fe...
Single cell bone marrow transplantation leaves no doubt as to the ability of bone marrow cells to differentiate and integrate into the endothelium, though the physiological significance of this remains controversial. Reported rates of bone marrow cell integration into the endothelium after injury vary widely, ranging from almost no cells to large percentages. Bone marrow cell maintenance of the...
In this paper, we established a delayed wound healing model on diabetic rat to mimic the pathophysiology of clinical patients who suffered from diabetic foot ulcers. We also evaluated if transplantation of allogeneic bone marrow-derived mesenchymal stem cells could promote the delayed wound healing and investigated the possible underlying biological mechanisms and stem cell behavior involved in...
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...
