Blastulation is the stage in early animal embryonic development that produces the blastula. In mammalian development the blastula develops into the blastocyst.

The ball of cells is referred to as a blastula, once cleavage has produced around 100 cells.

The development of multi-cellular organisms begins from a single-celled zygote, which undergoes rapid cell division to form the blastula.

These cells grow at a very rapid pace, and in humans, in days six through ten following ovulation, the blastocyst implants.

The term blastula refers to the period between 128-cell stage (2.25hpf, 8th zygotic cell cycle) and the beginning of gastrulation (5.25hpf, 14th zygotic cell ...
