Harnessing exosomes and hydrogels for advanced diabetic wound healing

Researchers from New York University have begun to explore exosomes, tiny membrane-bound vesicles, as promising tools for wound healing. These nanovesicles carry various biological materials – nucleic acids, proteins, and lipids – allowing them to mediate intercellular communication and influence processes such as tissue repair. By combining them with hydrogels, which are composed of networks of cross-linked polymers, the researchers showed that hydrogel-exosome combinations consistently lead to faster wound closure than either hydrogels or exosomes used alone.
