An injectable, self-healing hyaluronic acid-based hydrogel as a dual-responsive depot for extracellular vesicle delivery.
Extracellular vesicles (EVs) are promising therapeutic agents for regenerative medicine, but their clinical translation is hampered by poor retention at the target site. Hydrogels offer a promising strategy for localized EV delivery; however, achieving controlled release and cytocompatibility remains challenging. Here,...
