Efficient Angiogenesis-based Wound Healing Through Hydrogel Dressing with Extracellular Vesicles Release
Overview
Affiliations
Wound healing and angiogenesis remain challenges for both clinical and experimental research worldwide. Periosteum-derived extracellular vesicles (P-sEVs) delivered by hydrogel dressings provide a potential strategy for wound defects to promote fast healing. In this study, we designed a NAGA/GelMA/Laponite/glycerol hydrogel wound dressing that can release P-sEVs to accelerate angiogenesis and wound healing (named P-sEVs@hydrogel) (-acryloyl glycinamide, NAGA). The wound dressing showed multiple functions, including efficient angiogenesis, tissue adhesion and a physical barrier. P-sEVs significantly enhanced the proliferation, migration, and tube formation of endothelial cells . The results of experiments showed that P-sEVs@hydrogel accelerates the healing of a full-thickness defect wound model by stimulating the angiogenic process. The improved cell proliferation, tissue formation, remodeling, and re-epithelialization possibly resulted in the fast healing. This study shows that multifunctional hydrogel dressing combined with bioactive molecules can achieve fast and satisfactory wound healing in full-thickness wound defects and other related wounds.
