A blastocyst is a cellular mass that forms early in the process of embryo development in mammals. In humans, this stage of embryogenesis occurs five days after fertilization, when there are fewer than 100 cells in the mass. At this stage of development, the embryo has not yet implanted in the uterus.
The blastocyst is the second major stage of development, after the morula, for a newly fertilized individual once cell division has begun. Cells begin to differentiate, or become specialized, and have moved on to an outer/inner arrangement: the outer cells are called the trophoblast which will give rise to the placenta, and the inner are called the embryoblast (or inner cell mass) as they will give rise to the embryo.
