During embryo implantation, crosstalk between the endometrial epithelium and the blastocyst, especially the trophoblasts, is a prerequisite for successful implantation. During this crosstalk, various molecular and functional changes occur to promote synchrony between the embryo and the endometrium as well as the uterine cavity microenvironment. In the past few years, growing evidence has shown that endometrium‐derived exosomes play pivotal roles in the embryonic‐maternal crosstalk during implantation, although the exact mechanism of this crosstalk has yet to be determined. The presence of metalloproteinases has been reported in endometrium‐derived exosomes, implying the importance of these enzymes in exosome‐based crosstalk. Thus, in this review, we describe the potential roles of the metalloproteinases of endometrium‐derived exosomes in promoting embryo attachment and implantation. This …
