Peptide-modified chitosan hydrogels significantly promote skin wound healing in mice. A: Representative photographs of wounds in the control, peptide, chitosan hydrogel, and peptide + chitosan hydrogel groups taken 3, 5, and 7 days after the initial treatment in mice. B: The residual wound percentages in the control, peptide, chitosan hydrogel, and peptide + chitosan hydrogel groups (n = 3). C: α-SMA expression in the control, peptide, chitosan hydrogel, and peptide + chitosan hydrogel groups detected on days 3, 5, and 7 after the initial treatments as detected by immunohistochemical staining (scale bar: 50 μm). D: Mean α-SMA expression in the control, peptide, chitosan hydrogel, and peptide + chitosan hydrogel groups measured 3, 5, and 7 days after the initial treatments (n = 3).
