Rossant Lab


Janet Rossant, a developmental biologist, is an expert in stem cell research.
She studies the development of early mouse embryos to better understand human embryonic and stem cell development. Her work on the genetic control of early development led to an understanding of the origins of pluripotent stem cells and the discovery of trophoblast stem cells that give rise to the placenta. Rossant is intrigued by the potential interactions between the maternal microbiome and stem cell origins.
