Gross and histological evaluation of vaginal mucosa defects in each group. A Macroscopic observation of vaginal mucosa defects at days 7 and 14 after the operation. B Quantitative analysis of the wound closure ratio in each group. n = 5 per group. C H&E staining of repaired vaginal wall tissue in each group. Scale bar: 500 µm. D Masson staining of repaired vaginal wall tissue in each group. Scale bar: 100 µm. E Quantitative analysis of collagen area normalized to the connective area. *, P < 0.05, compared with the PBS group; #, P < 0.05, compared with the piGEL group; %, P < 0.05, compared with the sEVs group
