Loss of cavin1 and expression of p-caveolin-1 in pulmonary hypertension: Possible role in neointima formation

Figure 2 H&E stain of pulmonary arteries from the lungs of control (C), Monocrotaline (MCT, M), hypoxia (H) and MCT+ hypoxia (M+H) groups. The top row (size 86-111 μm) shows significant medial thickening in the M and H groups; The M+H artery reveals greater medial thickening and neointima. The smaller arteries (size 67-70 μm) from M+H group show almost complete obliteration of the lumen.
