Figure 7: Matrix protein level in SMC and endothelial cells from patients with aortic aneurysm with either tricuspid aortic valve (TAV) or bicuspid aortic valve (BAV) and controls (C) determined by Western blot. (a) Matrix protein level in SMC. The diagrams represent the results of densitometry. The bands were normalized by β-actin. C: ; TAV: ; BAV: . (b) Collagen I protein level in endothelial cell culture media.
