SeNPs downregulate epidermal hyperplasia by suppressing STAT3 and Ki67 expression. Immunofluorescence analysis was performed in skin tissue sections to determine the expression of a, b STAT3 and c, d Ki67 using confocal microscopy. The images were captured at × 400 magnification. Data represents Mean ± SD (n = 3). ****p < 0.0001 are significantly different from the normal control group; ^^^^p < 0.0001 are significantly different from the IMQ group
