research Ultrasound-Activated GelMA Hydrogel Loaded with MSC-EVs Promotes Functional Regeneration of Skin Vasculature, Nerves, and Appendages
This study found that combining ultrasound with a GelMA hydrogel able to deliver mesenchymal stem cell-derived vesicles significantly improved wound healing in a mouse model by enhancing fibroblast activity, promoting re-epithelialization, and facilitating hair follicle regeneration, highlighting a novel approach to skin regeneration therapy.
