The STAT3 transcription factor appears to play a fundamental role in trophoblast stem cells (TSC) and the development and maintenance of the trophectoderm and extraembryonic ectoderm lineages. The trophoblast lineage is derived from a stem cell population of the early embryo that gives rise to all embryo-derived cells of the placenta. Like the cells of the inner cell mass, TSC have the capacity for unlimited proliferation in vitro, for differentiation into a number of distinct cell types, and can contribute to placental tissues in vivo. Dr. Levy's group is characterizing the role of STAT3 in the trophoblast lineage using genetics, biochemistry, and cell culture approaches. This work may provide new molecular insight into fundamental mechanisms of implantation, placentation, and pregnancy success.
