Plateled-derived growth factor (PDGF) B immunoreactivity in pulmonary vessels in SScPAH, IPAH and PVOD. (Original magnification 200×). A) PDGF-B immunoreactivity in small vessel and capillaries in a patient with SScPAH. B) PDGF-B immunoreactivity in the intima layers of an arteriole with concentric laminar intimal fibrosis in a patient with SScPAH (see also 4B). C) PDGF-B immunoreactivity in a small vessel and (congested) capillaries in a PVOD patient. D) PDGF-B immunoreactivity in the basal side of the endothelium, the thickened intima and in smooth muscle cells in the hyperplastic media of an arteriole in a IPAH patient. E) PDGF-B immunoreactivity in stroma and endothelium of a plexiform lesion in an IPAH patient. In the center a glomeroid lesiom surrounded by vein-like branches (dilatation lesions).
