Figure 2. LAMP1 localization in the epididymis of turtle. LAMP1 immunolabeling (white arrowhead) in the epididymis during hibernation (A–D) 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.
