Blastulation. 1 - morula, 2 - blastula.

The blastula is an early stage of embryonic development in animals. It is produced by cleavage of a fertilized ovum and consisting of a spherical layer of cells surrounding a fluid-filled cavity. The blastula follows the morula and precedes the gastrula in the development sequence. A blastula has around 128 cells, with a large central cavity called the blastocoel. Also called blastosphere. A whitefish blastula is often used to help study the processes of mitosis in animal cells.The bastula is prevented from multiplying during the nuclearinjection stage.
