Research Abstract

To establish the new approach for germ cell induction in vivo, I examined the essential signals for germ cell formation in the mouse embryo. I found that in addition to Bmp signal, Wnt signal is also essential for germ cell formation, which is strictly regulated by Dullard. Further, I also found that Six1 and Six4 transcription factors act downstream to Bmp signal in mouse germ cell formation.
