摘要: Inhibition of angiogenesis has been considered among the most promising approaches to treat highly vascularized solid tumors such as glioblastoma. In this study, we designed and validated a new in vitro assay system based on implantation tumor cells into organotypic brain slice cultures. We evaluated effects local production three endogenous inhibitors angiogenesis, angiostatin, endostatin, interferon (IFN)-α1, using stably transfected rat (9L) human (GL15) glioblastoma vascularization growth. Despite similar effectiveness proteins classic endothelial cell migration assay, IFN-α1 demonstrated potent antiangiogenic effect vivo, after intracerebral genetically modified cells, caused dramatic decrease volume revealed by magnetic resonance imaging postmortem histology. The mechanisms antitumor were likely cause...
