Fig. 1From: Three-dimensional culture models of human endometrium for studying trophoblast-endometrium interaction during implantationThe process during the embryo implantation. The blastocyst implants to the maternal endometrium following sequential stages of apposition, adhesion and invasion. Each stage is associated with the production of molecular factors by both the blastocyst and the endometrium.
