Embryonic stem cells (ESCs) are derived from inner cell mass (ICM) of the blastocyst. In serum/LIF culture condition, they show variable expression of pluripotency genes that mark cell fluctuation between pluripotency and differentiation metastate. The ESCs subpopulation marked by zygotic genome activation gene (ZGA) signature, including , retains a wider differentiation potency than epiblast-derived ESCs. We have recently shown that retinoic acid (RA) significantly enhances Zscan4 cell population. However, it remains unexplored how RA initiates the ESCs to 2-cell like reprogramming. Here we found that RA is decisive for ESCs to 2C-like cell transition, and reconstructed the gene network surrounding . We revealed that RA regulates 2C-like population co-activating and . We provided novel evidence that RA dependent ESCs to 2C-like cell transition is regulated by , and antagonized by . Our suggested mechanism could shed light on the role of RA on ESC reprogramming.
胚胎干细胞(ESCs)来源于囊胚的内细胞团(ICM)。在血清/白血病抑制因子(LIF)培养条件下,它们显示出多能性基因的可变表达,这些基因标记着细胞在多能性和分化亚状态之间的波动。以合子基因组激活基因(ZGA)特征标记的胚胎干细胞亚群,包括……,比上胚层来源的胚胎干细胞保留了更广泛的分化潜能。我们最近发现,视黄酸(RA)显著增强了Zscan4细胞群体。然而,RA如何启动胚胎干细胞向2细胞样重编程仍未得到探索。在这里,我们发现RA对于胚胎干细胞向2C样细胞转变具有决定性作用,并重建了围绕……的基因网络。我们揭示,RA通过共同激活……和……来调节2C样群体。我们提供了新的证据,表明RA依赖的胚胎干细胞向2C样细胞转变受……调节,并被……拮抗。我们提出的机制可能有助于阐明RA在胚胎干细胞重编程中的作用。
