Pluripotent stem cells can be isolated from embryos or derived by reprogramming. Pluripotency is stabilized by an interconnected network of pluripotency genes that cooperatively regulate gene expression. Here we describe the molecular principles of pluripotency gene function and highlight post-transcriptional controls, particularly those induced by RNA-binding proteins and alternative splicing, as an important regulatory layer of pluripotency. We also discuss heterogeneity in pluripotency regulation, alternative pluripotency states and future directions of pluripotent stem cell research.
多能干细胞可以从胚胎中分离得到,也可以通过重编程获得。多能性由一个相互关联的多能性基因网络稳定,这些基因协同调节基因表达。本文描述了多能性基因功能的分子原理,并强调了转录后调控,特别是由 RNA 结合蛋白和可变剪接诱导的调控,作为多能性的一个重要调控层。我们还讨论了多能性调控的异质性、替代多能性状态以及多能干细胞研究的未来方向。
