Research Abstract

As the management team of the Grants-in-Aid for Scientific Research on Priority Areas titled “The Germline: Its Developmental Cycle and Epigenome Network”, we organized various scientific and social activities and promoted three major research projects: 1) cell fate determination for germline development; 2) epigenomic regulation in gametogenesis and meiosis; 3) epigenomic reprogramming in fertilization and early development. Our major scientific outcomes are: in vitro induction of primordial germ cells from pluripotent stem cells; discovery and correction of aberrant X-chromosome inactivation in cloned mice; dissection of the epigenomic regulatory networks in germ cells. To share the latest research results with the community, we made a website in Japanese and English and hosted four domestic and one international symposium. We also supported young scientists’ forum.
