对不同生长阶段分离的小鼠卵母细胞和减数分裂能力进行超微结构比较。通过透射电子显微镜检查核仁、核糖体、线粒体、内质网、高尔基复合体以及其他细胞器和卵母细胞内含物的渐进变化，作为卵母细胞大小的函数。哺乳动物卵母细胞的生长显然不仅涉及细胞的巨大增大，还涉及其整体代谢的广泛改变，这反映在不同生长阶段的卵母细胞的超微结构中。
An ultrastructural comparison of mouse oocytes isolated at various stages of growth and meiotic competence was carried out. Progressive changes in the nucleoli, ribosomes, mitochondria, endoplasmic reticulum, Golgi complex, and other organelles and inclusions of the oocyte were examined as a function of oocyte size by transmission electron microscopy. Growth of the mammalian oocyte apparently involves not just tremendous enlargement of the cell, but extensive alterations in its overall metabolism as reflected in the ultrastructure of the oocyte at various stages of growth.
