A. Glut1 immunohistochemistry on sections of 4 weeks growth glioma in ROSAmT/mG mice treated with anti-CSF1 or control antibodies. Anti-CSF1 antibody treatment induces a two-fold decrease in vessel caliber compared to control antibody (n=6 mice per group) (50µm depth stack). Statistical analysis: A.F. t-test; Error bars: A-C-F: meanSD; Scale bars: A-B-E: 150µm.
