Leydig Cell EM
Opossum testicular interstitial cells showing extensive smooth endoplasmic reticulum involved in testosterone synthesis.
A low-power electron micrograph showing several interstitial cells, one of which (above) contains cytoplasm of considerably greater density than the others. The most striking feature of the interstitial cells is the abundant agranular endoplasmic reticulmn (agr), which fills their cytoplasm and is in the form of a network of interconnected tubules. At the periphery of thc cells is an ectoplasmic zone (ect), which is relatively free of endoplasmic reticulum. The cytoplasm also contains mitochondria (m), in which large, homogeneous granules (g) sometimes occur (see Fig. 10). Various extensions of the Golgi zone (G) arc seen around the nucleus. Small, dark bodies (b) of unknown nature are also found in the cytoplasm. The denser cell contains an oblique section through a bundle (bun) of minute tubules, but it is difficult to make out detail because of the great density of the cytoplasm.
The edge of a seminiferous tubule (sere) is seen at lower right, and is flanked by one of the cells (lain) which contribute to the lamina propria of the tubule. X 6,200.
