The outer layer of the blastocyst forms the
The outer layer of trophoblast cells, resulting from compaction, pumps sodium ions into the blastocyst, which causes water to enter through osmosis and form the internal fluid-filled blastocyst cavity (blastocoel). The blastocoel, trophoblast cells, and inner cell mass are hallmarks of the blastocyst. [11] … Visa mer The blastocyst is a structure formed in the early embryonic development of mammals. It possesses an inner cell mass (ICM) also known as the embryoblast which subsequently forms the embryo, and an outer layer of Visa mer There are two types of blastomere cells: • The inner cell mass, also known as the embryoblast, gives rise to the primitive endoderm and the embryo proper (epiblast).
