The large luteal cells comprise the bulk of the bovine corpus luteum during the most active secretory period of the oestrous cycle. At least 3 types of granules were present in mid-luteal cells: microperoxisomes, primary lysosomes and secretory granules. Only the last appear to be exocytosed. The concentration of these secretory granules in the luteal cytoplasm correlated with the reported profile of progesterone secretion by these cells throughout the cycle. Changes in the cytoplasmic proportions of the other subcellular organelles were consistent with the mobilization of steroid precursors stored in lipid droplets, synthesis of increased amounts of progesterone and protein, and the packaging of these products into discrete secretory granules.
在发情周期最活跃的分泌期，大黄体细胞构成了牛黄体的主体。黄体中期细胞中至少存在3种类型的颗粒：微过氧化物酶体、初级溶酶体和分泌颗粒。似乎只有后者会被胞吐。这些分泌颗粒在黄体细胞质中的浓度与这些细胞在整个周期中报道的孕酮分泌情况相关。其他亚细胞器的细胞质比例变化与储存在脂滴中的类固醇前体的动员、孕酮和蛋白质合成量的增加以及这些产物包装成离散的分泌颗粒一致。
