Injectable hydrogels of recombinant human collagen type III and chitosan with antibacterial and antioxidative activities for wound healing

. Significantly, the rhCol III-CS2 hydrogel increased the deposition of collagen, thereby accelerating full-thickness wound healing. Collectively, this bioinspired hydrogel was a promising multifunctional dressing to reconfigure the damaged tissue without additional drugs, exogenous cytokines, or cells, providing an effective strategy for the repair and regeneration of skin wounds.
