Figure 2From: The roles of platelet-derived growth factors and their receptors in brain radiation necrosisRepresentative results of immunostaining of undamaged brain tissue (UB). PDGF-A, B, C, D and PDGFR-α were scarcely detectable in UB (A through E). PDGFR-β (F) was specifically expressed in endothelial cells in UB. Many normal cerebral blood vessels stained with PDGFR-β (F *) were detected in UB. Original magnification, ×200.Back to article page
