About this person
Specifically, she uses cellular and genetic manipulation techniques to study how genes control both normal and abnormal development of early mouse embryos. Rossant has discovered information on embryo development, how multiple types of stem cells are established, and the mechanisms by which genes control development. In 1998, her work helped lead to the discovery of the trophoblast stem cell, which has assisted in showing how congenital anomalies in the heart, blood vessels, and placenta can occur.
