Fig. 3. Cdon depletion induces the transition of VSMCs to osteoblast-like cells.
a Immunoblot analysis of VSMCs infected with shCont- or shCdon-expressing lentivirus. b Representative Alizarin Red staining images of the shCont- or shCdon-transduced VSMCs. Scale bar:100 μm. c Quantification of Alizarin Red staining in the VSMCs transduced with shCont- or shCdon-lentiviruses shown in panel (b). (n = 3). Data represent the means ± SEMs analyzed by Student’s t-test. ***P < 0.005. d Relative transcript levels of osteogenic markers and foam cell markers in control or Cdon-depleted VSMCs (n = 3). Data represent the means ± SEMs analyzed by Student’s t-test. **P < 0.01, ***P < 0.005. n.s. = not significant. e Representative images of senescence-associated β-galactosidase (SA-β-gal) staining in the control or Cdon-deficient VSMCs. Scale bar: 100 μm. f Quantification of the number of SA-β-gal-positive cells shown in panel (e) (n = 4). Data represent the means ± SEMs analyzed by Student’s t-test. ***P < 0.005. g Relative transcript levels of cellular senescence markers in the control or Cdon-deficient VSMCs (n = 3). Data represent the means ± SEMs analyzed by Student’s t-test. *P < 0.05, ***P < 0.005.
