Abstract

Maternal steroid hormones play a critical role in establishing the receptive phase of implantation. In addition to that, the embryo is able to modulate endometrial molecules during the apposition phase (chemokines) and the adhesion phase (adhesion and anti-adhesion molecules). Moreover, the human embryo also exerts a coordinated regulation of endometrial epithelial apoptosis during these implantation phases. In this work, we analyze the embryonic regulation of implantation in humans using an in vitro model.
