Role of adipokines in embryo implantation

Abstract

Embryo implantation is a complex process in which multiple molecules acting together under strict regulation. Studies showed the production of various adipokines and their receptors in the embryo and uterus, where they can influen ce the maternal-fetal transmission of metabolites and embryo implantation. Therefore, these cytokines have opened a novel area of study in the field of embryo–maternal cro sstalk during early pregnancy. In this respect, the involvement of adipokines has been widely reported in the regulation of both physiological and pathological aspects of the implantation process. However, the information about the role of some recently identi fied adipokines is limited. This review aims to highlight the role of various adipokines in embryo–maternal interactions, endometrial receptivity, and embryo implantation, as well as the underlying molecular mechanisms.
