Saliva-Exos accelerate wound healing in vivo. a Images of cutaneous wound in mice. b Wound healing rate in the three in vivo groups, mice treated with PBS, saliva, and saliva-Exos. c H&E staining of wound sections and quantification of scar widths in the three groups. d Blood flow in the wound site assessed by laser speckle contrast imaging and quantification of MPU ratio in the three groups. e Representative images of CD31 staining of wound sections. f Quantification of the number of CD31-positive cells in the three groups. **p < 0.01, ***p < 0.001, ***p < 0.0001; n = 6 per group
