Blastocoele Blastocyst Blastocyst with an inner cell mass and trophoblast. Carnegie stage 3 Days 5 Precursor morula Gives rise to primitive yolk sac 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.
