NF200 DAB staining results (a,b) and 5HT immunohistochemical results (c,d) in the injured spinal cord tissue at 12 weeks after injury (a–d). (a) Representative images of NF200-positive axons in the control and exercise groups. The right images are high-magnification images of the black boxes in the left images (Nos. 1–4) within the lesion cavities of contused spinal cords (outlined by black dashed lines). (b) The density of NF200-positive axons of the control and exercise groups (n = 4 per group). (c) Representative images of 5HT-positive axons (green) and GFAP-positive astrocytes (red) in the control and exercise groups. The right images are high-magnification images of the black boxes in the left images (Nos. 5–8) adjacent to the lesion cavities of contused spinal cords. (d) The density of 5HT-positive axons of the control and exercise groups (n = 4 per group). * p < 0.05 between the control and exercise groups by Mann–Whitney U test. Black and yellow scale bars = 500 μm, white scale bar = 100 μm, red scale bar = 50 μm.
