The NOS-related NADPH-diaphorase activity was studied by transmission electron microscopy in the peritubular myoid cells and fibroblasts of normal mouse testis. The reaction product was observed on the membranes of the endoplasmic reticulum, on the Golgi apparatus and nuclear envelope. The peritubular myoid cells and fibroblasts showed similar ultracytochemical features; the intensity of the enzymatic reaction was suggestive of an important role of the NOS/cGMP enzymatic system in these cells. Some hypotheses on the role of NO in the peritubular myoid cells and fibroblasts are proposed.
