Changes in expression of angiogenic growth factors and their receptors in leiomyoma compared with myometrium. Circles denote angiogenic growth factors, while rectangles denote their receptors. Blue denotes an increase, while pink denotes a decrease in expression. EGF, epidermal growth factor; HB-EGF, heparin-binding EGF; VEGF, vascular endothelial growth factor; bFGF, basic fibroblast growth factor; PDGF, platelet-derived growth factor; TGF-β, transforming growth factor-β; ADM, adrenomedullin.
