Nestin positive cells at the central canal of rat spinal cord transverse sections. (A) Nestin positive cells were shown in red fluorescence, and the cell nuclei were counterstained in blue. Scale bar: 25 μm. (B) Nestin immunoreactivity at the central canal of rat spinal cord transverse sections. The Nestin positivity peaked at 24 h post-injury, followed by a decreased trend in the Nestin immunoreactivity with the increasing post-injury time. Data are presented as mean ± SD. Statistically significant differences were shown compared to the 6-week sham group (**p < 0.01, ***p < 0.001). Statistically significant differences were revealed between groups (^#p < 0.05; ^###p < 0.001).
