摘要: Abstract Malignant gliomas are associated with a dysfunctional blood–tumor barrier (BTB) that causes substantial morbidity. Scatter factor/hepatocyte growth factor (SF/HGF) is multifunctional correlates glioma malignancy and has several biological properties suggest role in enhancing blood–glioma permeability. In this study, we examined the effects of cell SF/HGF expression on BTB permeability to horseradish peroxidase (HRP). Fischer 344 rats bearing intrastriatal 9L tumors engineered secrete (9L-SF) SF/HGF-negative control (9L-neo) received intracardiac injections HRP were rapidly decapitated. Densitometric analysis brain sections reacted diaminobenzidine showed significantly greater extravascular surrounding SF/HGF-secreting than 9L-neo comparable size (p
