RNA function in germ and stem cell biology

The integrity of the genome transmitted to the next generation intrinsically relies on cells of the germline. Processes that ensure germ cell development, genomic stability, and reproductive lifespan are essential for the long-term success of a species. We are interested in characterizing spermatogonial stem cell (SSC) populations that support fertility as well the regenerative capacity of the testis throughout adult life. In addition, we tackle fundamental questions regarding the mammalian germ line and heredity from an RNA perspective. Specifically, our research explores the contribution of non-coding RNA, RNA-binding proteins and RNA modification pathways to male and female germ cell development as well as homeostatic/regenerative spermatogenesis.
