Efficient Healing of Diabetic Wounds by MSC-EV-7A Composite Hydrogel via Suppression of Inflammation and Enhancement of Angiogenesis

Investigators proposed that MSC-extracellular vesicles (EVs) could be combined with histone deacetylase 7-derived 7-amino-acid peptide (7A) to greatly promote diabetic wound healing. The combination of EVs and 7A significantly improved the migration and proliferation of skin fibroblasts.
