Novel cellular evidence of lipophagy within the Sertoli cells during spermatogenesis in the turtle

Figure 5. Electron micrograph of Sertoli cells during consumption of lipid droplets via lipophagy in May. (A) Sertoli cells contained numerous lipid droplets. (B) Illustration of Fig. A (rectangular area) shows the lipid droplets in contact with a phagophore and autophagosomes (white arrow). (C) Lipid droplets enclosed in the autophagosome. (D) Higher magnification of the square from Fig. C. SC: Sertoli cell; LD: lipid droplets; IM: isolation membranes; Ap: autophagosome; Pg: phagophore; GC: germ cell; m: mitochondria; ER: endoplasmic reticulum. Scale bar= 5μm (A), 2μm (B, C) and1μm (D).
