The blastocyst is the structure formed in early mammalian embryogenesis, after the formation of the blastocele, but before implantation. It possesses an inner cell mass, or embryoblast, and an outer cell mass, or trophoblast.

The blastocyst is formed of pluripotent cells and go on to form the developing embryo. The outside layer of cells of the blastocyst goes on to form the placenta, and the inner ball of cells forms the embryo.
