Immunohistochemical stain of Ki67 and DSG1 in the EET of the NP, control, MP14, GF14, MP28, and GF28 groups on days 6 and 14: (a) Representative images of Ki67 staining localized in the EET on the wound area (upper-left and lower images). Black curved dotted lines indicate the DEJ, and the red arrows indicate the stained Ki67 in keratinocytes around the DEJ (upper-right image). Scale bar = 100 μm. (b) Representative image of DSG1 staining localized in the EET of the wound area. Black arrows indicate the stained DSG1 in the EET (upper image). The IHC stain images of DSG1 represent the skin samples (lower images). (c) Graph of EPI. (d) Positive-stained DSG1 to evaluate the re-epithelization of the wound bed. The EPIs are expressed as the means ± SDs (n = 6), with * p < 0.05 compared with the control group.
