Fig. 5. Localization of NORD-1. Representative image of two-serial sections of the penis after NORD-1 injection into the crura of the penis. In one slide, smooth muscle was detected by immunofluorescence staining with antibody to alpha-smooth muscle actin (α-SMA) (A, C). In another slide, NORD-1 was detected by approximately 620 nm excitation light (B, D). (A) and (B) reveal whole images of the corpus cavernosum (scale bar: 200 µm). (C) and (D) show enlargement images surrounded by yellow flame in (A) and (B) (scale bar: 100 µm).
