[Early embryogenesis in mammals: stem cells and first commitments steps.]

Abstract : In mammals, embryonic and extraembryonic cell lineages segregate during the first steps of cell differentiation in the preimplantation embryo. Indeed, mammal embryos contain very low energy stocks and thus get ready for implantation very early to be able to absorbe nutrients from the mother, first through the yolk sac and then through the placenta. These first steps involve classical genetic and morphogenetic processes as well as specific mechanisms of early embryo development such as epigenetic reprogramming and maintenance of pluripotent cells. Embryo analysis led to the isolation of embryonic stem (ES) cells, granted by the 2007 Nobel prize of Medicine (to M. Evans, M. Capecchi and O. Smithies) and which offer strong hopes for cell therapy. double dagger.
