Differences in immune cell infiltrations and cytokine concentrations. A Differences in the infiltration of CD45+, CD68+ and CD163+ cells (median cell counts per mm2) within each tumor area. B Differences in the immune cell infiltrates (median cell counts per mm2) between the tumor areas. C Overview on the distribution of absolute immune cell infiltrates (median cell counts per mm2) for the different tumor areas. D Median concentrations (in pg/ml) of IL-2, IL-6, IL-7 and VEGF in the CSF of GBM patients vs. controls as assessed by the multiplex assay
