Embryonic regulation of endometrial molecules in human implantation.
Embryonic implantation requires co-ordinated development of the blastocyst and the maternal endometrium. Considerable advances have been made in understanding the cell biology of these partner tissues separately. Nevertheless, communication between these tissues and the reciprocal effects of these tissues on each other constitutes an exciting and as yet unsolved paradigm in reproductive medicine. Crosstalk between the embryo, endometrium and the corpus luteum is known to occur in ruminants and primates, and, more specifically, endometrial-embryonic interactions are reported in rodents and primates. In this review, an in vitro model for analysing the interactions between human endometrial epithelium and blastocyst in the adhesion phase of embryonic implantation is presented. The results of investigations of embryonic regulation of endometrial epithelial molecules such as adhesion molecules, mucins, chemokines and cytoskeleton proteins are also presented.
