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. 這些細(xì)胞進(jìn)行自我調(diào)整，以致在細(xì)胞群內(nèi)部形成一個充滿液體的腔，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. 解凍后，33枚胚胎中有26枚(大多數(shù)胚胎含有2到10個細(xì)胞)發(fā)育到囊胚階段，此時囊胚腔已經(jīng)形成。

blastula Stage in embryonic development which represents the final product of cleavage stages, characterized by formation of the blastocoel. 囊胚代表胚胎發(fā)展的最后分裂階段,特徵為囊胚腔的形成。
