A blastula (blastocyst in mammals), is a sphere of cells surrounding a fluid-filled cavity called the blastocoel. The blastocoel contains amino acids, proteins, growth factors, sugars, ions and other components which are necessary for cellular differentiation. The blastocoel also allows blastomeres to move during the process of gastrulation. In Xenopus embryos, the blastula is composed of three different regions. The animal cap forms … WebThe 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 cycle, ...
