囊胚腔,卵裂腔,胚泡腔
These orient themselves so that a fluid-filled cavity, the blastocoel, forms inside the mass of cells. 这些细胞进行自我调整，以致在细胞群内部形成一个充满液体的腔，即囊胚腔。
After thawing, 26 of the 33 embryos (most of which were composed of between two and ten cells) deeloped to blastocyst stage in which the blastocoele is formed. 解冻后，33枚胚胎中有26枚(大多数胚胎含有2到10个细胞)发育到囊胚阶段，此时囊胚腔已经形成。

blastula Stage in embryonic development which represents the final product of cleavage stages, characterized by formation of the blastocoel. 囊胚代表胚胎发展的最后分裂阶段,特徵为囊胚腔的形成。
