Gene and protein expression of Ki67 in injury site of the external anal sphincter after laser, human adipose-derived stem cells (hADSCs), and combination of laser and hADSCs (laser + hADSCs) treatments. hADSCs labeled by DiI (red). Ki67 expression is observed in the hADSCs and laser groups (green). Data are presented as means ± SEM (n = 4 animal per group). **Significant level at p < 0.01 with the sphincterotomy group. ^#Significant level at p < 0.05 with the control group (intact animals). ^$Significant level at p < 0.05 with the laser + hADSCs group. ^†Significant level at p < 0.05 with the hADSCs group.
