Outline of Final Research Achievements

In mammalian embryos, the specified primordial germ cells undergo epigenetic reprogramming, in which repressive epigenetic marks dynamically change; however, the molecular details remains unknown. Recently, we have developed an in vitro system to induce primordial germ cell-like cells (PGCLCs) using human pluripotent stem cells (PSCs) as starting materials. In this research, we first evaluated various PSC clones regarding the induction efficiency into PGCLCs, and performed comparable analysis of repressive epigenetic states in the selected clones. We further examine the dynamics of repressive chromatin during the in vitro induction process.
