MSC-Exosomes Inhibited Apoptosis and Calcification in EPCs
(A) Anti-apoptosis of MSC-exosomes in TBHP-treated EPCs. (B) Capase-3, caspase-7, and caspase-9 in EPCs after treatment of MSC-exosomes. (C) Alizarin red staining and ALP staining of EPCs after treatment of MSC-exosomes (scale bars, 50 μm). (D) Runx2, BMP-2, and Sox9 in EPCs after treatment of MSC-exosomes. (E) Immunofluorescence of Runx2 protein in EPCs after treatment of MSC-exosomes (scale bars, 200 μm). Data are mean ± SD. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
