The structural changes in the granulosa lutein cells in the pregnant cows between 60 and 245 days, were observed. The polyhedral or pump cells has an acidophilic cytoplasm around the spherical nucleus. The glycogen granules increased in number up to 230 days of pregnancy. The lipid globules increased in size and amount during advanced pregnancy. The mitochondria showed a wide range of variations in shape and size. The matrix of many mitochondria contained dense inclusions which replaced the entire matrix in late pregnancy. The endoplasmic reticulum was chiefly of smooth type but a few stacks of the rough variety could be seen in the early days of pregnancy. Sometimes, whorls of smooth-surfaced endoplasmic reticulum enclosing mitochondria were seen. The Golgi complex was fully developed in the granulosa cells of all cases studied. The dense granules and lipid globules increased in size and number in the older corpora lutea. The cell surface showed numerous infolding of the plasma membrane.
观察了妊娠60至245天的母牛中黄体颗粒细胞的结构变化。多面体或泵状细胞在球形核周围有嗜酸性细胞质。糖原颗粒数量在妊娠230天前增加。妊娠后期脂质球的大小和数量增加。线粒体在形状和大小上有很大变化。许多线粒体的基质含有致密内含物，在妊娠后期取代了整个基质。内质网主要是光滑型，但在妊娠早期可见少量粗面内质网堆叠。有时可见光滑表面的内质网围绕线粒体形成的漩涡。在所研究的所有病例中，颗粒细胞中的高尔基体复合体均发育完全。在较老的黄体中，致密颗粒和脂质球的大小和数量增加。细胞表面显示出质膜的大量内褶。
