Figure 2From: Hypoxia-inducible factor-1 α/platelet derived growth factor axis in HIV-associated pulmonary vascular remodelingIncrease in medial wall thickness of pulmonary arteries in HIV-Tg rats compared with WT-rats. VVG-stained sections from each animal were evaluated for medial wall thickness of pulmonary arteries with diameter size ranging from 50 μm-250 μm. P < = 0.001, HIV-Tg rats vs. WT controls.Back to article page
