Mammalian reproduction is critically dependent on the trophoblast cell lineage, which assures proper establishment of maternal-fetal interactions during pregnancy. Specification of trophoblast cell lineage begins with the development of the trophectoderm (TE) in preimplantation embryos. Subsequently, other trophoblast cell types arise with the progression of pregnancy. Studies with transgenic animal models as well as trophoblast stem/progenitor cells have implicated distinct transcriptional and epigenetic regulators in trophoblast lineage development. This review focuses on our current understanding of transcriptional and epigenetic mechanisms regulating specification, determination, maintenance and differentiation of trophoblast cells.
哺乳动物的繁殖严重依赖于滋养层细胞谱系,该谱系可确保孕期母胎相互作用的正常建立。滋养层细胞谱系的特化始于植入前胚胎中滋养外胚层(TE)的发育。随后,随着孕期的进展会出现其他类型的滋养层细胞。对转基因动物模型以及滋养层干/祖细胞的研究表明,不同的转录和表观遗传调节因子参与了滋养层谱系的发育。本综述重点阐述了我们目前对调节滋养层细胞特化、决定、维持和分化的转录及表观遗传机制的理解。
