Platelet-derived growth factor (PDGF) expression in normal prenatal human thymus. In (a) a strong immunoreactivity to PDGF in the media of large vessels and in the medullary epithelial cell. In (b) a detail of the cortico-medullary junction showing PDGF expression in the connective tissue septae and a strong immunoreactivity in the medulla. A strong immunoreactivity to PDGF in the epithelial network of the medulla (c) and in Hassall corpuscles (d). Original magnification: a, ×40; b, ×100; c, ×400; d, ×1000.
