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

Figure 4. Electron micrograph of seminiferous tubules in May. (A) Seminiferous tubules contain type B spermatogonia and early spermatocytes. (B) Type-A spermatogonia. (C) Type-B spermatogonia. (D) The numerous lipid droplets are observed around leptotene spermatocytes. (E) Sertoli cells contained lipid droplets. Bm: basal membrane; SgB: spermatogonia type B; Ps: primary spermatocyte; SC: Sertoli cell; LD: lipid droplets; Lp: leptotene spermatocyte; N: nucleus; m: mitochondria; ax: axonome; Pc: peritubular cell; St: stem cell. Scale bar= 10μm (A) and 5μm (B, C, D, E).
