Partial genetic inactivation of Tgfb1 and Smad3 inhibits AV calcification in 10–12-week-old Kl–/– mice. (A–H) Alizarin red staining of aortic valve in wild-type (A,E), Kl/ (B,F), Kl/;Tgfb1± (C,G), and Kl/;Smad3± (D,H) mice. Images (E–H) are the magnified views of the corresponding boxed region (A–D). Scale bars = (A–D), 200 μm; (E–F), 50 μm. (I) Quantitative analysis of calcification. Quantification of calcification was done on multiple serial sections from each animal per group by using NIH-Image J software. Values indicate mean ± SD, and significant “p-values” were given on the top of histograms.
