The implantation process is currently considered the most relevant limiting factor for
successful pregnancy. It is evident that molecular interactions at the embryo-maternal
interface at the time of implantation are crucial in order to understand the mechanisms of
embryonic implantation. The principal aim of this study is to demonstrate the existence of
specific communication pathways between the human embryo and endometrium. The
molecular interactions appears to be initiated by the endometrium in the presence of an …
