摘要
通过存在于卵母细胞中的一些未确定的因子,以成年细胞对动物进行克隆证实成年细胞能被重编程为胚胎干细胞(ESCs)。近年来,某些转录因子被发现具有诱导体细胞且有多潜能性的特性,从而可以在不使用卵母细胞的情况下获得性能上与胚胎干细胞大体一致的诱导多能干细胞(iPS)。iPS细胞为细胞多能性机制的研究、特定疾病模型的建立以及在再生医学等方面的应用提供了一个独特的平台。这一重大科研发现,不仅避免了因使用ES而导致的关于伦理道德的长期争论,而且将干细胞研究推向了一个全新的领域。鉴于此,就目前国内外iPS研究进展作一简要概述。
It is confirmed that the adult cells can be re-programmed to embryonic stem cells(ESCs) by presenting some certain factors in oocytes in the clone process of animals. In recent years, some transcription factors that can induce pluripotent stem cells(iPS) have been identified and which made it possible to obtain induced pluripotent stem cells similar to embryonic, stem cells, iPS provides a unique platform to study the pluripotent mechanism and to establish some specific disease models. This major scientific discovery can not only aw)id the use of ES which involves ethics debate, but also lead the stem cell research to a new field.
