Figure 5. IFNα prevents and reverses pulmonary vascular remodeling in SUH rats.

Figure 5

(A) Representative photomicrographs of small pulmonary arterioles (≤50 μm) from an SUH rat with vascular occlusion (V.O.) of 0%, <50%, and >50%. (B) Percent of small pulmonary arterioles (≤50 μm) with V.O. 0%, <50%, or >50% in SUH treatment groups (50 arterioles per animal, n = 4 animals per group). (C) Representative photomicrographs of pulmonary arterioles (≤100 μm) from SUH treatment groups demonstrating differences in wall thickness. (D) % Wall thickness in pulmonary arterioles (≤100 μm) from SUH treatment groups (20 arterioles per animal, n = 4 animals per group).
