英文摘要
1.CD34 antigen is a novel marker for human hematopoietic stem/progenitor cells. Two cell fractions, CD34^<low> and CD34^<high>, were prepared from steady-state human peripheral blood (PB) on the basis of CD34 antigen expression. The content of CD34^+CD45^+ cells in the CD34^<low> and CD34^<high> cell fractions was 74.8% and 88.8%, respectively, and the frequency of thrombopoietin (TPO)-supported colony-forming unit megakaryocytes (CFU-Meg) in the CD34^<low> cell fraction was 1.9 times higher than that in CD34^<high>. The CFU-Meg in CD34^<high> were more radiosensitive than those in CD34^<low>, indicating that steady-state human PB contains different types of CFU-Meg. TPO plus interleukin-3 was the optimal combination for survival of both types of CFU-Meg after X irradiation. These results suggest that multiple combinations with TPO will be helpful in cytokine therapy for post-irradiation thrombocytopenia.2.Mature megakaryocytes induced from the culture of PB CD34^+ cells with TPO are s … More hown high radio sensitivity, however, normal pro-platelet formation occurred after X irradiation. These results suggest that the influence of X irradiation to the end of thrombopoiesis is small.3.Low concentration of Epigallocatechin-3-gallate (EGCg,100 nM), a major green tea polyphenol, reduce the risk factor from radiation damage in megakaryocytopoiesis, suggesting the medical application of EGCg for the treatment of thrombocytopenia.4.CFU-Meg are more radiosensitive progenitors to cabon ion beam than X-ray. The induction of γ-H2AX, a marker of DNA double strand break (DSB), by carbon ion beam in CD34^+ cells was not enhanced by cytokine treatment such as that of X-ray. These results showed that the DSB repair of CFU-Meg by cytokine was lesser in progenitors to carbon ion beam than X-ray.5.A combination of IL-3 plus TPO would be an optimal choice for the regeneration of megakaryocytopoiesis and thrombopoiesis from X-irradiated stem cells. Our results suggest that nearly normal megakaryocytopoiesis and thrombopoiesis can be induced from X-irradiated stem cells by stimulation with appropriate cytokine combinations. Less
