WebBackground Successful embryo implantation requires the attachment of a blastocyst to the receptive endometrial epithelium, which was disturbed in the women with recurrent implantation failure (RIF). WebTo prevent the blastocyst from adhering to an area with poor chances of implantation, an important role is played by the repellent activity of MUC-1, which is widely expressed throughout the endometrium and, surprisingly, even increases before implantation. ... At this stage, adhesion molecules such as integrins and cadherins intervene to ...

Thus, decreased integrin-3β in the high let-7 g embryo may be a possible reason for impaired embryo implantation ability.
WebFeb 1, 2024 · The first step is apposition which is an unsteady adhesion, in which all the surface of the blastocyst has a potential for this connection. At this step, the blastocyst expresses cell adhesion molecules such as L-selectin on the surface of invasive trophoblast and rolls on the endometrial lining to adjust its orientation with the inner cell ...
