Abstract
In rodents, gene knock out in mice have vastly improved our understanding of the role of Cx genes in mouse placental development: Cx26 in transplacental uptake of glucose, Cx31 in the proliferative process of trophoblastic cells and Cx45 in placental vascularisation. In human, it appears that Cx43 allows a GJIC required for the fusion process of cytotrophoblastic cells leading to the formation of the syncytiotrophoblast, the site of the numerous placental functions. On other hands, Cx40 plays a critical role in the switch from a proliferative to an invasive phenotype of the trophoblastic cells invading the endometrium. Owing to the striking diversity of Cx expression in placental structures, we must be careful when extrapolating findings from one species to another.
