Fig. 3From: Extracellular vesicles in the pathogenesis of rheumatoid arthritis and osteoarthritis a Concentration of EVs in synovial fluid (x axis) versus the average size of EVs (y axis). There was no significant difference in either measurement between EVs from OA patients and EVs from normal patients. b Top row, chondrocytes treated with DAPI and unlabeled EVs; bottom row, chondrocytes treated with DAPI and PKH67-labeled EVs. Left column, only DAPI labeling; middle column, only PKH67 labeling; right column, combination of DAPI and PKH67 labeling. EV extracellular vesicle, OA osteoarthritisBack to article page
