Fig. 2. Copolypeptide hydrogel accelerates wound healing. (A) Representative images of wounds of the 10% copolypeptide hydrogel group and the control group over the course of healing process. The unit of the rulers over the pictures represents 1 millimeter. (B) Schematic diagram of the wound closure process of the two groups. (C) Wound healing closure rates of these two groups. The rates were presented as a percentage of the initial wound area on day 0. Statistical differences were performed using one-way analysis of variance (ANOVA). **P < 0.01, *P < 0.05, compared to control group, n > 6.
