Figure 10. Recovery results of EV delivery scaffolds. (A) Promoted regeneration of glands and reduction of muscular dystrophy by hUCMSC-EVs laden collagen scaffolds for endometrium injury; (B) faster wound closing (picture) and more formation of new epidermis (staining) by MSC-EVs immobilized on PEI-conjugated PCL scaffolds treating large skin wound.
