Résumé : | Upon its implantation in the uterus of the mother in mammals, the embryo is composed by three morphologically distinct tissues: the Epiblast (Epi), the Trophectoderm (TE) and the Primitive Endoderm (PrE). Both Epi and PrE are formed from the same cell homogeneous population called the Inner Cell Mass (ICM). Based on our studies, we discuss in this review what molecular interactions are necessary for the specification of these two lineages. For this, we have combined a biological approach with mathematical modeling. We have shown the central role of the gene regulation group composed by NANOG, FGF4, GATA6 and FGFR2 for Epi/PrE cell specification. |
