Fig. 8. The Ig2 domain of Cdon is sufficient to attenuate the osteogenic conversion of VSMCs.

a Immunoblot analysis of Cdon-Fc (the entire Cdon ectodomain fused to Fc) and Ig2-Fc (Ig2 domain fused to Fc) purified from cell supernatants. b Immunoblot analysis of VSMCs treated with CM and each purified protein. IgG served as a control. c Alizarin Red staining images of the VSMCs treated with control or CM in combination with Cdon-Fc, Ig2-Fc, or IgG. Scale bar = 100 μm. d Quantification of Alizarin Red staining shown in panel (c) (n = 3). Data represent the means ± SEMs analyzed by one-way ANOVA. ***P < 0.005. e Relative transcript levels of Axin2, Runx2, and ALPL in the VSMCs treated with control or CM in combination with Cdon-Fc, Ig2-Fc, or IgG.
