Abstract:
Human peri-implantation development remains a black box of developmental biology, as embryos at this stage are practically inaccessible for studies due to the ethical considerations. Moreover, we learn only little using conventional model organisms such as mouse, because early human development strikingly differs in terms of timing, morphology and signalling cues. In my previous work, I established an in vitro experimental system using human pluripotent stem cells that closely recapitulates peri-implantation period of epiblast development. This system allows to model the distinct features of human early embryo development closely reproducing temporal, transcriptional and morphological characteristics, including formation of three-dimensional structures. Understanding these processes also reveals how these human-specific features of embryogenesis evolved during the evolution.
