Scientific summary

We are deciphering the molecular and cellular mechanisms of the first cell lineages differentiation during early mouse development. Our goal is to understand both in vivo and in vitro the process of induction and formation of embryonic and extra-embryonic tissues during the first stages of embryogenesis. Our focus is on the molecular mechanisms driving epiblast versus Primitive Endoderm specification during preimplantation and, later, on the differentiation of the Primitive Endoderm and its derivatives, including the formation of the epithelial structure and its transition toward mesenchyme.

Our work is closely linked to embryonic and extraembryonic stem cell research.
