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 trophoblast cells called the trophectoderm. This layer surrounds the inner cell mass and a fluid-filled cavity known as the blastocoel. In the late blastocyst the trophectoderm i… WebThe hollow cellular mass formed during the early development consisting of cells forming the trophectoderm, the inner cell mass, and the fluid-filled cavity or the blastocoel is known as the blastocyst.
