Platelet-derived growth factor (PDGF) is a potent mitogen for mesenchymal cells and glial cells. For a better understanding of the role of PDGF B-chain in the brain, the expression of PDGF B-chain was examined immunohistochemically in penetrating injury to the rat brain. Shrunken neurons were distributed with enhanced PDGF B-chain-related immunoreactivity (PBRI) in the vicinity of the lesion during a period from day 1 to day 4 post injury. Platelet-derived growth factor B-chain-related immunoreactivity was transiently observed also in the cytoplasm of the numerous brain macrophages in the lesion on day 3 and day 4. These distributions of PBRI in the lesion were closely related to the neovascularization and astrogliosis there. The close time and spatial correlation between the expression of PBRI and cellular responses to injury seen in this study suggests PDGF B-chain has an important role in the healing process of cerebral wound.
