Figure 3

GDF-15 immunohistochemistry in pulmonary arterial hypertension (PAH). GDF-15 protein expression in PAH) showing a strong signal in the endothelial cell layer (arrows) of a pulmonary artery with media hypertrophy. The smooth muscle cells (arrowheads) of the remodeled pulmonary artery are lacking significant GDF-15 protein expression. Macrophages around the pulmonary artery stain positive for GDF-15 (asterisks). Original magnification: × 200.
