Fig. 5From: Sublethal dose of irradiation enhances invasion of malignant glioma cells through p53-MMP 2 pathway in U87MG mouse brain tumor modelHematoxyin and Eosin staining of brain tissues. Exposure to radiation was more invasive and exhibited multiple tumor cell satellites, while non-radiated tumor showed less invasiveness and clear margin. a Non-radiated group, b Radiated group (Single dose), c Radiated group (fractionation)Back to article page
