From: LIPOPHAGY: a novel form of steroidogenic activity within the LEYDIG cell during the reproductive cycle of turtle

Fig. 5

Electron micrograph of the Leydig cell in the testis of the Chinese soft-shelled turtle. The Leydig cell is compactly exhibited during reproductive phase (a) and loosely exhibited during hibernation phase (b) at the interstitium. The cytoplasm of the Leydig cell is rich in vesicular endoplasmic reticulum (c), lipid droplets, mitochondria and tubular endoplasmic reticulum (d). White thin arrow: gap junction; black thin arrow: finger-like prolongations in the interdigitation space; black thick arrow: dividing mitochondria. The illustration indicates a magnified view of the white and black square. N: nucleus; ER: endoplasmic reticulum; LD: lipid droplets; M: mitochondria. Scale bar = 8 μm (a), 6 μm (b) and 2 μm (c-d)
