E. MRC1 immunohistochemistry on 3 weeks growth glioma in ROSAmTmG::Pdgfb-iCre mouse following MHCII-FITC labeled IV injection at 6 or 24h (5µm depth stack). Note the segregation of MRC1 and MHCII cell labeling at 6 hours and the overlapping of these two markers at 24 hours (n=5 mice per group). Statistical analysis: E. t-test. Error bars: E: 50µm.
