子宫内膜接受性研究进展

Advances in understanding endometrial receptivity

子宫内膜接受性是指子宫具有接受并容纳活性胚胎并成功建立妊娠的能力。子宫内膜进入接受态是胚泡在子宫内膜中定位、黏附、侵入并成功着床的关键。“着床窗口”是指子宫内膜只在特定的一段时期内对胚胎具有接受性，

Embryo implantation is a complex physiological process,which depends on synchronized embryo development and uterus into the receptive stage. The receptivity of uterus to active embryos is the key step for embryo implantation. The establishment of uterine receptivity involves in morphological changes of luminal epithelium, steroid hormones, various cytokines, micro-RNAs and other factors. This review summarizes the latest advances in the studies on uterine receptivity and its molecular regulation.
