in vivo cellular evidence of autophagic associated spermiophagy within the principal cells during sperm storage in epididymis of the turtle

Figure 2. LAMP1 localization in the epididymis of turtle. LAMP1 immunolabeling (white arrowhead) in the epididymis during hibernation (AD) and non-hibernation (E) PBS served as negative control. (F) White arrow indicates interaction of luminal spermatozoa with epithelia of epididymis. Rectangular area showed enlarged area. Scale bar: (A, B, E) 20 μm and (C, D) 10 μm.
