Cell Mass Internal

The inner cell mass is the main component of the embryonic trophoblast and the main source of cellular elements of the chorion. The cells are formed by mitotic expansion and initiation from the embryoid bruch in the amnion region to the formation of the trophoblastoma cell. The inner cell mass takes place in its area of ​​the cytoarchitectonics of the trophoblast behind the embryoid mass of the inner cell mass of the embryo. The embryo was recognized to contain trophoblast cells that originate from the embryonic axle and later fill the trophoblast section that takes place in the area under the amniotomy
