Effects of transplantation of oral mucosa stem cells on DNA fragmentation in the spinal cord tissues. Upper: Photomicrographs of terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL)-positive cells in the spinal cord tissues. The scale bar represents 40 μm in upper panels and 150 μm in lower panels. Lower: Number of TUNEL-positive cells in each group. (A) Sham-operation group, (B) SCI-induced group, and (C) SCI-induced and oral mucosa stem cell transplantation group. * represents P < 0.05 as compared to the sham-operation group. # represents P < 0.05 as compared to the SCI-induced group.
