摘 要:生精干细胞(spermatogonial stem cells, SSCs)是动物出生后保持分裂能力的生殖细胞,其通过自身复制从而终生存在,并不停地进行减数分裂而分化成精子。然而,最近的研究发现生精干细胞具有一定的多能性,在体外可被培养和诱导成多能性细胞,显示生精干细胞是再生医学和细胞治疗疾病的另一理想祖细胞来源。该综述将着重讨论生精干细胞的多能性研究情况和相关问题。

Abstract: Spermatogonial stem cells (SSCs) are the only postnatal mitotic germ cells in the body;  they are capable of self-renewal throughout life, while undergoing spermatogenesis through meiosis to give rise to haploid sperm. Interestingly, recent studies demonstrated that SSCs could be induced to pluripotency in culture. Thus, SSCs could be an alternative cell source for regenerative medicine and cell therapy of diseases. The focus of this review is on the recent advances in the study of SSC pluripotency.

    
Key words: stem cell; spermatogonial stem cell; self-renewal; germ cell; pluripotency; gPS
