Fig. 4From: BM-MSC-derived exosomes alleviate radiation-induced bone loss by restoring the function of recipient BM-MSCs and activating Wnt/β-catenin signalingExosomes accelerate DNA repair in BM-MSCs after irradiation. a Immunofluorescence staining of γ-H2AX in BM-MSCs after irradiation cocultured with PBS or exosomes at different time points. b Quantitative analysis of γ-H2AX foci per cell. The data are presented as the mean ± SD. *p < 0.05, **p < 0.01. c Western blot analysis of γ-H2AXBack to article page
