Cadmium-induced impairment of spermatozoa development by reducing exosomal-MVBs secretion: a novel pathway
Figure 3. Electron micrograph of MVBs in the seminiferous tubules of control (A) and cadmium (B) treated group. (A) Seminiferous tubules containing several MVBs and limited formation of autophagosome. (B) Seminiferous tubules containing numerous formations of autophagosome and limited MVBs. Ee: early endosome; MVBs: multivesicular bodies; Ac: acromion process; Sp: spermatozoa; ER: endoplasmic reticulum; L: lysosome; (arrow) autophagosome. Scale bars 2 μm.
