AGEs induce calcification in HASMCs. (A) Dose-dependent study of AGEs-induced calcification in HASMCs at AGEs concentrations from 0 to 100 mg/L. Von Kossa staining (black) in HASMCs after AGEs treatment for 2 weeks. scale bar = 100 µm (×10). (B) Immunofluorescence staining of calcification-related proteins with 24 h’ AGEs treatment at indicated concentrations. The green GFP signal represents the calcified protein OPN. The blue DAPI signal represents the nuclear region, scale bar, 25 µm. (C) Western blot analysis of the expression of RAGE and other calcification-related proteins (β-catenin, OPG, OPN, MMP7, BMP2, Runx2) with 24 h’ treatment. Data are presented as the fold change compared with the control group. Each point represents the mean ± SD (n = 3/group); * p < 0.05, ** p < 0.01, *** p < 0.001.
