LL-37/CS accelerates wound healing. a. Representative images of wounds of four tested groups, ruler units in mm. b. The results are expressed as the percentage of the initial wound on days 3, 5, 7, 9, 11, 13, 15, 19, and 21. Statistical significance compared with control group (mean ± SD; n = 3). c. LL-37/CS facilitated an increase in the density of new capillaries and re-epithelialization of deep tissue injury. Wound sections (n = 3) were stained with hematoxylin and eosin (H&E). Representative sections are presented for all four groups on days 14 and 21 after application of treatment (× 10 and × 20, mean ± SD; n = 3). *P < 0.05, **P < 0.01 and ***P < 0.001 compared with control group
