Fig. 2From: Curcumin primed ADMSCs derived small extracellular vesicle exert enhanced protective effects on osteoarthritis by inhibiting oxidative stress and chondrocyte apoptosis Characterization of sEV-CUR. a Representative TEM images of sEV and sEV-CUR, scale bar: 100 nm; b average particle diameter distribution of sEV and sEV-CUR was analyzed by a nano-flow cytometry; c Western blot analysis of CD63, TSG101, and GM130 from ADMSCs, sEV, and sEV-CUR. CD63 and TSG101: sEV surface marker; GM130: the Golgi marker; d Zeta potential of sEV and sEV-CUR (n = 12). N.S., not significantBack to article page
