The occurrence of vascular regeneration at the wound site. a Fluorescence imaging of wound tissues in the control, MSCs-ADM scaffold, and MSCs-CHS/ADM scaffold groups on days 7, 14, 21, and 28. Green, red, and blue represent GFP+-cells, α-SMA+-cells, and nuclei, respectively. Scale bar, 200 μm. b Fluorescence intensities of GFP with different treatment times. Quantitative analysis of the vessel density and d diameter of the MSCs-ADM scaffold, MSCs-CHS/ADM scaffold and control groups on days 7, 14, 21, and 28. Data are expressed as the mean values and SD (n = 5). **p < 0.01, *p < 0.05
