植入时人类胚胎的重塑对于成功怀孕是必不可少的。然而,它仍然是神秘的,因为实验障碍困扰着这个发展阶段的研究。在这里,我们建立了一个体外系统,在没有母体组织的情况下培养人类胚胎直至着床阶段,并揭示了早期人类形态发生的关键事件。这些包括分离的多能胚胎和胚胎外谱系和形态发生重排导致:产生一个双层盘,形成一个前羊膜腔内的胚胎谱系,外观的前景卵黄囊,和滋养层分化。使用人类胚胎和人类多能干细胞,我们表明胚胎谱系的重组是由细胞极化介导的,导致空腔形成。总之,我们的研究结果表明,在人类发育的这个阶段,关键的重塑事件是胚胎自主的,突出了人类胚胎的显着和意想不到的自我组织特性。
Remodelling of the human embryo at implantation is indispensable for successful pregnancy. Yet it has remained mysterious because of the experimental hurdles that beset the study of this developmental phase. Here, we establish an in vitro system to culture human embryos through implantation stages in the absence of maternal tissues and reveal the key events of early human morphogenesis. These include segregation of the pluripotent embryonic and extra-embryonic lineages and morphogenetic re-arrangements leading to: generation of a bi-laminar disc, formation of a pro-amniotic cavity within the embryonic lineage, appearance of the prospective yolk sac, and trophoblast differentiation. Using human embryos and human pluripotent stem cells, we show that the reorganisation of the embryonic lineage is mediated by cellular polarisation leading to cavity formation. Together, our results indicate that the critical remodelling events at this stage of human development are embryo-autonomous highlighting the remarkable and unanticipated self-organising properties of human embryos.
