Enhanced caveolin-1 expression in smooth muscle cells: Possible prelude to neointima formation

Figure 5 Immunofluorescence study depicting the expression of caveolin-1 (green) and smooth muscle α actin (red) in pulmonary arteries from controls, monocrotaline, hypoxia and monocrotaline + Hypoxia groups at 2 and 4 wk. The accompanying bar graphs (n = 4-5) shows the % arteries exhibiting the presence of caveolin-1 in endothelium (EC) and in smooth muscle layer (SMC). ^aP < 0.05 vs C. C: Controls; M: Monocrotaline; H: Hypoxia; M + H: Monocrotaline + hypoxia.
