Research summary
All tissues of the body originate from a ball of pluripotent cells, located in the inner of cell mass of the late blastocyst. We found previously unknown morphogenic events polarization, apical constriction and lumenogenesis that reorganize the embryonic lineage during implantation. These morphogenic changes can be induced and studied in ES cells grown in 3D culture, when proper polarization cues are provided. Our findings are contrary to the long term believe that programed cell death transforms the epiblast from a simple ball of cells into cup shaped epithelium.
