DPSC-Exos rescued IFN-γ-caused death and AQP5 downregulation of salivary gland epithelial cells (SGEC). A The cell viability of salivary gland epithelial cells was detected by CCK-8 assay. The expression pattern of AQP5 analyzed by RT-qPCR (B), Western blot analysis (C, D), and immunofluorescence staining (E, F). Scale bar: 20 μm. Data are presented as the mean ± SD, n = 3. Significant effect of the treatment, *p < 0.05, **p < 0.01, ***p < 0.001
