摘    要:胚胎干细胞(ESC)是一种多能干细胞,具有向生殖细胞分化的能力,由于具有致瘤性和伦理问题,限制了ESC向临床应用发展的前景。成体干细胞(ASC)也是一类多能干细胞,理论上也能分化为生殖细胞,但诱导分化过程往往受到阻滞。诱导性多能干细胞(iPS)是一种具有多能性的重编程体细胞,一定程度上可替代ESC用于基础和临床研究。目前,全球不孕不育的发生率呈逐年递增的趋势,充分认识干细胞向生殖细胞分化的机制是解决该难题的重要理论前提。就各种干细胞向生殖细胞分化的研究进展作一综述。

关 键 词:干细胞  胚胎干细胞  成体干细胞  多能干细胞  生殖细胞  分化

Abstract:Embryonic stem cells(ESCs) are pluripotent stem cells, which can be induced to differentiate into germ cells. Because of their tumorigenicity and ethical issues, their clinical application were astricted. Adult stem cells(ASCs) are multipotent stem cells, they have potential to differentiate into germ cells in theory, but the inducing process are often complicated. Induced pluripotent stem cells(iPS) are the pluripotent and reprogrammed somatic cells which can be used to replace ESC in basic and clinical research, to some extent. The morbidity of infertility increased in these years, so it is important to understand the mechanism of germ cell differentiation for potential infertility treatment. Here, we reviewed the recent progress on the derivation of germ cells from stem cells.
Keywords:Stem cells  Embryonic stem cells  Adult stem cells  Multipotent stem cells  Germ cells  Differentiation
