囊胚（blastula）指的是 内部产生囊胚液、囊胚腔的胚胎，囊胚中所有细胞都没有开始分化，这个阶段之后胚胎开始出现分化。 经过卵裂，受精卵被分割成很多小细胞，这些由小细胞组成的中空球形体称为囊胚。卵裂结束，囊胚细胞要经过一系列复杂的运动，导致细胞空间相互关系的改变。

Embryonic stem cells are multiple capable cells that come from the inner cell mass of blastula,which possess the capability of differentiated pleiotropia and long-term generation. They have been widely used in many aspects of life science.
胚胎干细胞(embryonic stem cell,ES细胞)是来源于囊胚内细胞团的一种多能细胞,具有分化的多向性和长期增殖的能力,已被广泛用于生命科学的许多领域,它潜在的医学应用也成为世界范围内的研究热点。
