ASC-derived exosomes alleviate the aging of MSCs and treat OA. A Experimental design; B Transmission electron microscopy image showing ASCs-derived exosomes as spherical or cup-shaped; C Microcomputed tomography scan showing bone erosion. The treatment effect was better in the ASC-derived exosome treatment group; D Safranin O and fast green staining images showing that ASC-derived exosome treatment is effective for cartilage regeneration; Reproduced with permission from [69]. © 2021, Oxford University Press.
