A blastocoel(e) or blastocele (also called blastocyst cavity,[1] cleavage cavity or segmentation cavity) is the fluid-filled central region of a blastocyst. A blastocoele forms during embryogenesis when a zygote (a fertilized ovum) divides into many cells through mitosis.

The adjectival of "blastocoel(e)" is blastocoelic.

A blastocoel can be described as the first cell cavity formed as the embryo enlarges. It is essential for later gastrulation.
