Recent research has focused on the development of drug-loaded hydrogels for wound healing. A carboxymethyl chitosan-gelatin hydrogel was chemically cross-linked using genipin as the cross-linking agent to deliver both substance P and DMOG. The synthesized hydrogels showed good biocompatibility and physicochemical properties, with the SP and DMOG combination promoting cell proliferation and facilitating wound healing in vivo. These findings suggest the potential application of this co-loaded drug hydrogel as a wound dressing material.
Recent efforts have focused on preparing drug-loaded hydrogel for wound healing. In order to obtain an ideal hydrogel dressing for skin wound repair, a carboxymethyl chitosan-gelatin hydrogel was prepared for co-delivery of SP (substance P) and DMOG (dimethyloxallyl glycine) by a chemical cross-linking method using genipin as the cross-linking agent. The synthesized hydrogels have good biocompatibility and physicochemical properties due to the low toxicity of the hydrogel material. The three-dimensional network structure of the hydrogels supports cell migration and proliferation, and the combination of SP and DMOG drugs exhibited strong effects on cell proliferation. Moreover, the co-loaded drug hydrogels could significantly promote wound healing in vivo, and provide a potential hydrogel for wound healing.
