An electron micrograph of a section from the testis of a rat from group I showing the basal lamina (BL) of seminiferous tubule (ST) and a myoid cell (My). The nucleus (N1) of sertoli cell (SC) shows a characteristic longitudinal fold (LF) and a rim of peripheral dense chromatin, the cytoplasm contains mitochondria (Mi) and lipid droplets (Li). The interstitial tissue revealed Leydig cell (Ld) having large rounded euchromatic nucleus (N) with a prominent nucleolus (n), its cytoplasm contains mitochondria (M), SER (S) and some lipid droplets (L) (TEM × 3000).
