The bone marrow microenvironment comprises multiple cell niches derived from bone marrow mesenchymal stem cells. However, the molecular mechanism of bone marrow mesenchymal stem cell differentiation is poorly understood. The transcription factor GATA2 is indispensable for hematopoietic stem cell function as well as other hematopoietic lineages, suggesting that it may maintain bone marrow mesenc...

Background: Multiple myeloma (MM) is a malignant plasma cell proliferative disorder with limited immunotherapy treatment because of T cell dysfunction. Objective: To investigate the immunomodulatory function of bone marrow mesenchymal stromal cells (MM-BMSCs) on CD8+ T cells. Methods: Proliferation and cytotoxicity were detected by c...

background: in recent years, adipose tissue, due to the stem cells contained within, has found a new special place in laboratory and clinical applications. these adipose‑derived stem cells (adscs) have the same characteristics of bone marrow mesenchymal stem cells (bmscs). although bone marrow (bm) is not easily accessible and its procurements may be painful, most patients possess excess fat wh...

With respect to radiation damage to humans, it is important to seek possible radioprotectants to modify the normal response of biological systems to radiation-induced toxicity or lethality. For this reasons, the search for less-toxic radiation radioprotectants has spurred interest in the development of different compounds. The radioprotective effects of citrus extract were investigated by using...

acute myeloid leukemia (aml-m7) is a type of pediatric aml accounting for 3–10% of primary childhood aml and children may present with a broad variety of symptoms including low-grade fever, diarrhea, easy bruising, failure to gain weight and life-threatening conditions. we report a rare case of aml .a 26-month-old boy who presented with weakness and fatigue. he was diagnosed as a case of amlm-7...

background: anti-hla-antibodies are known to affect the allograft survival in transplant recipient patients. objective: the aim of this study was to evaluate the association between anti-hla antibodies and kidney allograft outcomes, particularly in recipients with concur-rent donor bone marrow cell infusion (dbmi). methods: between june 2006 and may 2007, forty living unrelated donor kidney tra...

introduction : use of adipose-derived stem cells (adscs) is a suggested hypothesis to enhance the regeneration of bone defects. this technique is of particular interest since adscs are more easily accessible via a non-invasive harvesting technique compared to bone marrow stem cells (bmscs). this study sought to assess the efficacy of adsc implantation for regeneration of localized mandibular bo...

We report here a useful method for elimination of small cell lung cancer cells in vitro from bone marrow. A monoclonal antibody, TFS-2, which mediates complement lysis and recognizes an antigen present on small cell lung cancer cells but not lymphoid cells or bone marrow cells, was used to clear infiltrated bone marrow. The antibody in the presence of complement effectively killed tumor cells, ...

Introduction: As an inherited neurodegenerative disease, Huntington's disease is accompanied with wide neuronal degeneration in neostriatum and neocortex. Progress of the disease causes disabling clinical effects on movements, recognition and physiology of the body, and finally results in death. At this stage of knowledge we are, there is no effective therapeutic strategy for diminishing the mo...
