再生障碍性贫血(简称再障)是造血功能衰竭所致的综合症,其发病机理可以是造血干细胞量的缺乏或质的缺陷,可以是造血微环境的缺陷或是由于细胞或体液调节造血组织的缺陷所致。为了探索再障的发病机理,我们对14例再障病人的骨髓进行了粒单系造血祖细胞 GM-CFU_c 的体外培养,混合细胞培培及再障病人血清的抑制实验,报告 Aplastic anemia (referred to as aplastic anemia) is a syndrome caused by hematopoietic failure, its pathogenesis can be a lack of hematopoietic stem cell or quality defects, can be defects in the hematopoietic micro-environment or due to cell or body fluid regulation of hematopoietic tissue Due to defects. In order to explore the pathogenesis of aplastic anemia, 14 cases of aplastic anemia in patients with bone marrow mononuclear hematopoietic progenitors GM-CFU_c in vitro culture, mixed cell culture and aplastic anemia in patients with serum inhibition test report
