αSMA expression in scars of partial thickness burn wounds at PBD 42.

Presence of myofibroblasts in the scars of the burn wounds was assessed by staining αSMA in tissue sections of PBD 42. A) Images of αSMA expression (brown) in scars of the control, systemic and topical Captopril-treated animals at PBD 42. B) The αSMA-positive signal was analyzed as percentage of the area fraction in the scars of the different treatment groups. Similar αSMA-positive area fractions were measured for all treatments at PBD 42.
