Expression of PDGF and PDGF receptors in human astrocytoma operation specimens supports the existence of an autocrine loop

Abstract excerpt

Established cell lines derived from human malignant astrocytomas typically express a combination of platelet-derived growth factor (PDGF) and PDGF receptor which could form an autocrine loop. In this study, we screened for the essential components of a PDGF autocrine loop in fresh surgical isolates of human astrocytomas, using in situ hybridization and immunohistochemical techniques. Eight malignant astrocytomas...
