Macrophage-derived exosomes alleviated DNA damage in MLE-12 cells exposed to different irradiations. A, B, γ-H2AX expression level was determined by western blot assay. C, D, Relative qualification of γ-H2AX content in MLE-12 cells after irradiation. E, The number of γ-H2AX foci per cell in MLE-12 cells exposed to IR. F, Immunofluorescence staining of MLE-12 cells after γ-H2AX staining (green) and DAPI staining (blue). *P < 0.05, **P < 0.01, *** P < 0.001,****P < 0.0001
