Fig. 2. Application of exosomes. Schematic representation of the potential applications of exosomes in wound healing, chondral defect repair, anticancer drug delivery. Exosomes can be loaded with endogenous cargos or intentionally changed molecules in a variety of ways, and many exosome delivery routes for treatment have been developed. Exosomes, on the other hand, require targeted tactics to boost medication efficacy. Exosomes generated from stem cells have been discovered to offer therapeutic promise for a wide range of injuries and disorders, including bone regeneration and wound repair.
