Quantification of MAP2 immunoreactivity 28 days post injury. Representative photomicrographs showing MAP-2 immunoreactivity in ventral and dorsal horns of the spinal cord of sham control (A), VPA 400 mg/kg treated (B) and untreated SCI (C) groups. The brown pixels are immunopositive and the blue pixels are hematoxylin staining. (D) Percentage of MAP2 positive pixels. A significant difference between 400 mg/kg VPA treated, untreated SCI and sham control groups were observed. Scale bar 50 and 200 µm; Graphs indicate the mean ± SEM; **P<0.05 (compared to the sham control and 400 mg/kg VPA groups); *P<0.05 (compared to sham control and untreated SCI groups).
