诱导多能干细胞 (iPS) 的诱导培养与鉴定

Induction and characterization of induced pluripotent stem (iPS) cells: a review

摘要:

通过外源转录调控因子的诱导，使成体细胞重编程为胚胎干细胞 (ES细胞) 样的多能细胞，这种细胞称为诱导多能干细胞 (iPS细胞)，这一方法被称为iPS技术。目前，iPS技术已先后在小鼠、人、猕猴、大鼠和猪中成功应用，建立了相应的iPS细胞系，并获得了iPS细胞嵌合小鼠和四倍体克隆小鼠。尽管iPS与ES细胞在形态和生长特性上有许多相同之处，但iPS细胞的建立需要较独特的诱导培养体系和鉴定方法。以下结合近年来iPS技术的发展和本实验室的相关研究，对iPS细胞的建立和培养体系的优化进行了深入探讨。

Abstract:

The somatic cells can be induced into ES-like stem cells when retrovirally infected the defined transcription factors including Oct4, Sox2, Klf4 and c-Myc. These ES-like cells are named induced pluripotent stem (iPS) cells and this method is called iPS technology. Until the end of 2009, iPS cell lines have been generated in various animal species, such as mouse, human, rhesus monkey, rat and pig. Mouse iPS cells are also used to generate chimera mice and viable mice through the tetraploid complementation. Although iPS cells are extremely similar to ES cells in both morphology and growth features, to generate iPS cells do need the defined culture procedures. Based on the update global iPS technology development and the iPS studies in our laboratory, this paper focused on the establishment of iPS cell lines and improvement of iPS cell culture condition.
