Abstract
Embryo implantation requires a reciprocal interaction between the blastocyst and endometrium
and is associated with complex regulatory mechanisms. Since their discovery, microRNAs
have become prominent regulatory candidates, providing missing links for many biological
pathways. In recent years, microRNAs have been implicated as one of the important
players in the regulation of multiple physiological functions of the endometrium.
This review aims to present recent knowledge pertaining to the diverse aspects of
microRNAs in the embryo–endometrial cross talk. We will focus on the role of microRNAs
in decidualization. Next, we will review recent studies investigating the role of
microRNAs in recurrent pregnancy loss. Finally, we will discuss the role of microRNAs
in the tissue invasion of implantation and compare that with tissue invasion in cancers.
