Effect of ASC-CM on wound healing. A Effect of ASC-CM versus the control (DMEM, EGF, and MSC-CM) on wound healing speed. The ASC-CM group had the fastest healing rate, which was completed by day 16. B Effect of ASC-CM vs. control (DMEM, EGF, and MSC-CM) on wound healing quality. The group that received ASC-CM had the thickest dermis, the most skin appendages, the most α-SMA positive vessels, and the least number of PCNA positive cells; Reproduced with permission from [76]. © 2019 Xiaoli Rong et al.
