Each ventricle was weighed and the ratio of RV weight to LV plus septum weight (RV/LV + Sp) was calculated. Lungs were fixed with 4% buffered paraformaldehyde for 24 h, embedded in paraffin, and cut into 4-μm-thick sections. Hematoxylineosin (HE) and Elastica van Gieson (EVG) stainings were performed using standard protocols. Immunofluorescence staining was performed using a primary anti-α-smooth muscle actin (α-SMA) mouse antibody
