Fig. 3From: Exosome-mediated crosstalk between epithelial cells amplifies the cell injury cascade in CaOx stone formationEffects of exosomes on the oxidative stress injury and the activation of the MAPK signalling pathway in HK2 cells. A EXO(S) enhanced the ROS level of HK2 cells. B MDA, CAT and SOD levels in HK2 cells stimulated with exosomes derived from different conditions. C Western blot assays showed the expression levels of the MAPK signalling pathway components in the HK2 cells stimulated with EXO(C) or EXO(S). The data are expressed as the mean ± SE. ∗P < 0.05 compared with the HK2 group. EXO(C) represents exosomes derived from HK2 cells without CaOx stimulation, while EXO(S) represents exosomes derived from HK2 cells stimulated with CaOxBack to article page
