摘　　要：胚胎干细胞(embryonic stem cell,ES细胞)是指由胚胎内细胞团(inner cell mass,ICM)细胞经体外抑制培养而筛选得到的细胞,具有无限增殖潜能,在体外可以向造血细胞分化,有可能为造血干细胞移植和血细胞输注开辟新的来源.此外,ES细胞向造血干/祖细胞的定向诱导分化也为阐明哺乳动物造血发育的细胞和分子机制提供了良好的体外模型.对ES细胞向造血干/祖细胞定向分化的研究进展进行了综述.Embryonic stem cells（ESCs） are pluripotent cells derived from the inner cell mass of blastocyst-stage embryos, possessing permanent self-renewal and indefinite proliferative capacity in vitro. And ESCs could differentiate into the hematopoietic cell fate. Therefore ESCs may provide an alternative for hematopoietic stem cell transplantation and blood cells transfusion. Furthermore, ESCs differentiation could also provide a powerful model system to better understand the hematopoietic development and the mechanism involved. The current status for efforts to differentiate ESCs into hematopoietic lineages were reviewed.
