Gamete final maturation, fertilization, and embryo cleavage occur in the oviduct. It is known that oviductal luminal fluid composition differentially changes in the presence of oocytes, spermatozoa or embryos, prompting for a molecular cross-talk between the gametes/embryo and the oviductal epithelium. However, our understanding of the regulatory molecular mechanisms of gamete/embryo-maternal cross-talk is still fragmentary and controversial. The deciphering of these mechanism...
