PF-127/hADSCs-Exos complexes promote cutaneous wound healing. a Representative images of the skin wound healing in each group on days 0, 1, 4, 7, 10, and 13. b Quantitation data of the ratio of the wound healing in each group. c Wounded skin sections stained with H&E in diverse groups on days 4, 7, 10, and 13 post-wounding. A representative biopsy from F127/hADSCs-Exo groups showed a normal intact hair follicle (blue arrow). Scale bar = 50 μm. d Representative H&E staining images of full-thickness wounds on days 13. Scale bar = 1250 μm. e Length between wound edges was calculated. In b and e, data are shown as mean ± SEM; n = 6 for each group. *p-value < 0.05, **p-value < 0.01, ***p-value < 0.001, ****p-value < 0.0001 vs vehicle control group
