Fig. 3.

Reduction of apoptotic cells in testes of TRPV1 KO mice. (A) Microphotographs of testis sections of young and old mice. The right panel shows enlarged images. Scale bar, 50 μm. (B) TUNEL-labeled apoptotic cells in the testicular cells. Scale bar, 30 μm. (C) Quantitative analysis of TUNEL-positive cells. The number of cells showing red (PI-stained cells) was divided by the number showing green (TUNEL-positive cells). *p < 0.05 compared to the WT. Each bar represents the mean ± SD of four experiments. PC and TUNEL (+) represent positive control treated with DNase I and TUNEL-positive, respectively.
