The lactating cow mammary secretory epithelial cell is very active synthetically and contains numerous very pleomorphic mitochondria. Cup- and ring-shaped mitochondria are frequent and many are extremely elongated. Preferential localization of mitochondria in the basal region, or at the lateral margins of the secretory cell adjacent to intraepithelial monocytes have been observed. Occasional mitochondria show one or several very densely staining cristae with a lattice pattern. Mitochondria are frequently seen closely associated with the tonofilament-desmosomal complex. These structures and associations are present after immersion or perfusion fixation of mammary gland from several breeds of cow; their possible significance is discussed.
泌乳奶牛的乳腺分泌上皮细胞合成活性非常高，含有大量形态多样的线粒体。杯状和环状线粒体很常见，许多线粒体极度细长。已观察到线粒体优先定位于基底区域，或位于分泌细胞与上皮内单核细胞相邻的侧缘。偶尔可见线粒体有一个或几个染色极深的呈晶格状的嵴。经常可以看到线粒体与张力丝-桥粒复合体紧密相连。在对多个奶牛品种的乳腺进行浸入或灌注固定后，这些结构和联系依然存在；文中讨论了它们可能具有的意义。
