Structural Characterization and Wound Healing Activity of Sulfated Glycosaminoglycans from Acipenser Baerii Cartilage: Potential Regulation of Fibroblast Function

This study found that a chitosan, chondroitin sulfate, and hyaluronic acid scaffold improved wound healing in rats by promoting immune-stromal interactions, reducing inflammation, and supporting tissue regeneration with ~91% wound closure by day 17 compared to ~63% in controls.

This narrative review examines the structure-function relationship in bioactive biopolymers used to promote healing in chronic wounds, emphasizing diabetic ulcers, and underscores the importance of characterizing these biopolymers to enhance their bioactivity for better tissue regeneration outcomes.

The researchers reported that hydrogels made from methacrylated glycol chitosan and hyaluronic acid with chondroitin sulfate may be suitable for load bearing soft tissue repair, showing enhanced chondrocyte viability and metabolic activity.

This review discusses the roles and mechanisms of glycosaminoglycans in wound healing and presents challenges and potential applications for GAG-based biomaterials without reporting new experimental results.

This study reported that a newly developed hydrogel composed of recombinant type I collagen and chitosan, incorporating a metal–polyphenol structure, demonstrated strong mechanical and healing properties, effectively promoting wound healing in a full-thickness skin defect model.
