Research Description:

We use human and rhesus embryonic stem cells and rhesus embryos to study primate placental organogenesis. The first differentiation event in mammalian development is the specification of the trophectoderm lineage that will give rise to the placental trophoblasts, and the placenta is the first functional fetal organ.

Our central hypothesis is that the formation of the placenta relies on an interplay of extrinsic signals and intrinsic transcriptional regulatory pathways. We have developed systems in which to study placental morphogenesis by probing cell-cell and cell-matrix interactions with human ES cell co-culture systems and in vitro differentiation paradigms, and novel rhesus monkey embryo and ES cell in vitro and in vivo implantation models.
