characterization of megakaryocyte progenitor cells differentiated from umbilical cord blood cd133+ and cd133– cells
objective: this study was performed to determine the immunophenotype of megakaryocyte progenitor cells differentiated from ucb cd133+ and cd133− cells under the effects of interleukin–3 (il–3), interleukin–6 (il–6), stem cell factor (scf) and thrombopoietin (tpo) in vitro. materials and methods: cd133+and cd133− cells were isolated by using cd133 isolation kit following the manufacturer’s instr...
متن کاملEfficient retroviral-mediated gene transfer to human cord blood stem cells with in vivo repopulating potential.
Recent studies have shown efficient gene transfer to primitive progenitors in human cord blood (CB) when the cells are incubated in retrovirus-containing supernatants on fibronectin-coated dishes. We have now used this approach to achieve efficient gene transfer to human CB cells with the capacity to regenerate lymphoid and myeloid progeny in nonobese diabetic (NOD)/severe combined immunodefici...
متن کاملthe high yield expansion and megakaryocytic differentiation of human umbilical cord blood cd133+ cells
objective: despite of many benefits, umbilical cord blood (ucb) hematopoietic stem cell (hsc) transplantation is associated with low number of stem cells and slow engraftment; in particular of platelets. so, expanded hscs and co-transfusion of megakaryocyte (mk) progenitor cells can shorten this period. in this study, we evaluated the cytokine conditions for maximum expansion and mk differentia...
متن کاملSCID-repopulating cell activity of human cord blood-derived CD34- cells assured by intra-bone marrow injection.
Precise analysis of human CD34-negative (CD34(-)) hematopoietic stem cells (HSCs) has been hindered by the lack of a simple and reliable assay system of these rare cells. Here, we successfully identify human cord blood-derived CD34(-) severe combined immunodeficiency (SCID)- repopulating cells (SRCs) with extensive lymphoid and myeloid repopulating ability using the intra-bone marrow injection ...
متن کاملDelta-1 enhances marrow and thymus repopulating ability of human CD34(+)CD38(-) cord blood cells.
We investigated the effect of Notch signaling, a known regulator of cell fate in numerous developmental systems, on human hematopoietic precursors. We show that activation of endogenous Notch signaling in human CD34(+)CD38(-) cord blood precursors with immobilized Delta-1 in serum-free cultures containing fibronectin and hematopoietic growth factors inhibited myeloid differentiation and induced...
