Abstract

Bone marrow specimens from 11 patients with myelofibrosis with myeloid metaplasia (MMM) and seven normal controls were studied immunohistochemically to determine expression of transforming growth factor β (TGF-β), platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF) and corresponding receptors. Staining distribution and intensity for TGF-β, PDGF, VEGF, TGF-β type II receptor, a receptor for PDGF, and receptors for VEGF and bFGF were similar in patients and controls. Bone marrow from 10 MMM patients showed increased TGF-β type I receptor (TGF-βRI) expression in small vessel endothelial cells. Eight patient specimens had bFGF overexpression in megakaryocytes. Increased microvessel density and decreased concentration of bFGF-staining stromal cells accompanied these changes. Microvascular TGF-βRI upregulation and bFGF overexpression by megakaryocytes may cause bone marrow microenvironmental changes in MMM patients.
