Ultraviolet radiation–induced bystander effects (UV-RIBEs) can be induced by exosome transfer. (A) The component showed a diameter from 50 to 80 nm with nanoparticle tracking analysis (NTA) method. (B) The exosomes were visualized as a typical tea tray-like structure with transmission electron microscopy. (C) Expression of typical proteins marker of exosome was higher than that in the cell protein group (P < 0.05).
