AbstractInjectable hydrogels with high anti-inflammatory and wound-healing properties are highly desirable for clinical application. In the present study, injectable hydrogels were prepared based on carboxymethyl chitosan and oxidized hyaluronic acid. Blueberry anthocyanins (BA), which are known for their antioxidant and antiinflammatory properties, were successfully loaded into the hydrogels. The gelation kinetics and mechanical properties of the hydrogels were investigated. Oxidized hyaluronic acid with an oxidation degree of 38.1% conferred a suitable gelation time (similar to 70 s) and mechanical properties (76.0 kPa compression stress at strain of 80%) of the hydrogel. The injectable BA-loaded hydrogel significantly accelerated the wound healing process in a full-thickness skin wound model in rats, promoted epithelial and tissue regeneration, exerted antiinflammatory effects, and promoted collagen deposition and angiogenesis. Besides, the hydrogel could upregulate the expression of VEGF and IL-10 proteins, downregulate the NF-kappa B level, and promote macrophage transformation from M1 phenotype to M2. The promotion of the BA-loaded hydrogel on wound healing were mainly realized by its biological effects, including antioxidant and anti-inflammatory effects, and regulation of various wound healing related factors. The results suggested that BA and the hydrogels exert synergistic effects in promoting wound healing. Injectable BA-loaded hydrogels appear to be promising candidates for wound healing application.
