Effect of adipose-derived stem cells exosomes cross-linked chitosan-αβ-glycerophosphate thermosensitive hydrogel on deep burn wounds

Figure 2 The effect of chitosan-αβ-glycerophosphate hydrogel crosslinked with adipose-derived stem cell exosomes on the healing rate of deep burn wounds in rats. A: Wound healing images of the four groups at 4, 7, and 14 days after wound treatment; B: Wound healing rates (%) of the four groups at 4, 7, and 14 days after wound treatment. ^aP < 0.05, ^bP < 0.01. ASC-Exos: Adipose-derived stem cell exosomes; CS: Chitosan.
