Representative slides of pulmonary arterioles obtained from control Wistar and from spontaneously hypertensive rats. Hematoxyllin-Eosin method staining (A; scale bars: 50 μm). Morphometry on pulmonary arterioles expressed as the medial thickness percentage versus the pulmonary artery external diameter in control Wistar rats (n = 6; white bars) and in spontaneously hypertensive rats (n = 6; black bars) pigs (B). Values are expressed as mean ± SEM. $ 0.01 < p < 0.05 compared to the control pulmonary artery.
