Reproductive Endocrinology and Science

Deviations from the norm can prevent the establishment of pregnancy or contribute to obstetrical disorders associated with aberrant placentation. Through basic and translational research, our mission is to identify the critical cellular and molecular events that are required for successful implantation and to understand their relationship with the pathologies of early pregnancy. Our objective is therefore to understand the biology of the developing blastocyst, which requires the differentiation of the trophectoderm—its outer epithelium—into invasive trophoblast cells and the maintenance of a cohort of pluripotent embryonic stem cells. We thus focus on the developing blastocyst, trophectoderm, and pluripotent embryonic stem cells and investigate the interactions between the uterine endometrium and implanting blastocyst at the inception of pregnancy. We are evaluating agents that would provide cellular and molecular evidence of successful and pathologic implantation.
