Nuclei are stained with Hoechst 33342 (blue). Scale bars: 50 µm. (D) Quantitative analysis of the IL‐10 and iNOS positive area percentage on day 7. n = 6. (E) Representative images showing the expression of collagen I and collagen III in the wound region from mice in different groups on day 7. Scale bars: 100 µm. (F) Quantitative analysis of collagen I and collagen III positive area percentage on day 7. n = 6. (G) Representative images showing the expression of collagen I and collagen III in the wound region from mice in different groups on day 14. Scale bars: 100 µm. (H) Quantitative analysis of the collagen I and collagen III positive area percentage on day 14. n = 6. (I) Representative immunofluorescent staining of CD31 (red), β3‐Tubulin (TUBB3, green), and Cytokeratin 18 (K19, yellow) in the wound regions of mice in different groups on day 14. Nuclei are visualized with Hoechst 33342 (blue). Scale bars: 50 µm. (J) Quantitative analysis of CD31, TUBB3, and K19 positive area percentage on day 14. n = 6. Data are shown as mean ± s.e.m.; One‐way ANOVA with Fisher's LSD test (E, J, I); Values sharing the same letter are not significantly different (p > 0.05).
