Abstract:

Implantation of the embryo is a key step in the process of conception which involves complex factors. Successful implantation entails a viable embryo to be implanted into an acceptable endometrium at an appropriate time, and a state of synchronous communication between the embryo and the endometrium. Errors in any part of the implantation process will affect the pregnancy rate, wherein decreased endometrial receptivity may be implicated as one of the major causes of infertility. During the early stage of implantation, endometrial epithelial cells undergo epithelial-mesenchymal transition to facilitate embryo adhesion, followed by decidualization of endometrial stromal cells to provide a suitable environment for embryo development. This suggests that epithelial-mesenchymal transition and decidualization is the fundamental condition for maintaining the receptive state of the endometrium, and an acceptable endometrium is the biological basis for embryo implantation and full development.
