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.
3. The blastocyst has an outer-layer of cells called the trophoblast, which will eventually form the protective placenta. Inside the trophoblast is a group of cells called the inner cell mass. The organism in a stage between zygote to fetus is called an embryo* and the cells are called embryonic stem cells.he blastocyst has an outer-layer of cells called the trophoblast, which will eventually form the protective placenta.
