We studied recovery of peripheral blood- and bone marrow-derived myeloid progenitor cells (CFU-G,M) in 29 patients who received bone marrow transplants 2 mo to 8.5 yr previously. All patients had normal levels of peripheral blood neutrophils, normal bone marrow cellularity, and a normal myeloid-erythroid ratio. Both peripheral blood- and bone marrow-derived CFU-G,M were markedly reduced compare...

Several sugar structures have been reported to be necessary for haemopoiesis. We analysed the haematological phenotypes of transgenic mice expressing beta-1,4 N-acetylglucosaminyltransferase III (GnT-III), which forms bisecting N-acetylglucosamine on asparagine-linked oligosaccharides. In the transgenic mice, the GnT-III activity was elevated in bone marrow, spleen and peripheral blood and in i...

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...

Both cultured Bone Marrow Mesenchymal Stem Cells (BMSCs) and non-cultured Bone Marrow Mononuclear Cells (BM-MNCs) can improve random-pattern skin flap survival. However, whether prior culture expansion of bone marrow cells is beneficial for this therapy remains unclear. In the current study, the protective effects of BM-MNCs and BMSCs derived from identical bone marrow aspirates were compared i...

BACKGROUND Bone marrow-derived stem cell transplantation is a potentially viable therapeutic option for the treatment of neurodegenerative disease. MATERIAL/METHODS We have isolated bone marrow stem cells by standard method. We then evaluated the survival of rats' bone marrow mononuclear cells implanted in rats' brain. The cells were extracted from rats' femurs, and marked for monitoring purp...

Therapeutic angiogenesis can be induced by the implantation of bone marrow mononuclear cells. We investigated the roles of mature mononuclear cell and stem cell fractions in bone marrow in this treatment. Although CD34 is the most popular marker for stem cell selection for inducing therapeutic angiogenesis, we separated CD117-positive cells (CD117+) from mature bone marrow mononuclear cells [CD...

objective(s): intracerebral injection of bone marrow stromal cells (bmscs) is being investigated as a therapeutic tool to prevent alzheimer's disease (ad). our aim was to investigate the effects of bmscs by intrathecal injection in ad rat model. materials and methods: bmscs were obtained from the bone marrow of wistar rat and transplanted into ad rat model via intrathecal injection. the ra...

OBJECTIVES Cellular cardiomyoplasty with isolated skeletal myoblasts and bone marrow mononuclear cells is an encouraging therapeutic strategy for heart failure. We investigated the achievements accomplished with combined cell therapy of skeletal myoblast and bone marrow mononuclear cell transplantation to the ischemic canine myocardium. METHODS Autologous skeletal myoblasts (1 x 10(8)) and au...

Quantitative determinations were made of the capacity of isogenic bone marrow, spleen, and thymic cells from primed and/or nonprimed mice to repopulate the hemopoietic tissues and to mount an inflammatory and antibody response to specific antigen (tetanus toxoid) in heavily irradiated and reconstituted recipients. Spleen cells from primed mice but not from normal mice had the capacity to adopti...
