Engineering chitosan fibers with MSC-exosome cargo: a clinically translatable multifunctional dressing for regenerative therapy in infected wound management

This study successfully developed a chitosan fiber-based exosome composite dressing system, which effectively coordinates infection control and tissue regeneration through a triple mechanism of "structural water-locking, mechanical adaptation, and bioactive synergy." This material provides a scalable solution for chronic wound management and shows promising clinical application prospects.
