Topical application of adipose-derived stem cells (ASCs) increases wound epithelialization as measured by high-resolution ultrasound. (a) Epithelized area estimated by ultrasound: (i) score 0 = incomplete epithelialization; (ii) score 1 = partial epithelialization; (iii) score 2 = complete epithelialization with irregular and uneven epithelium; (iv) score 3 = complete epithelialization with regular and even epithelium. (b) Re-epithelized area measurement at 7 and 15 days after application of ASCs. Analysis of wound re-epithelialized determined by high-resolution ultrasound. (c) Combination of wound epithelialization score from both 7 and 15 days determined by high-resolution ultrasound (n = 6, ^*p < 0.05, unpaired t test). Error bars represent standard error of mean
