Brain mononuclear cells were extracted, counted and stained for CD45 and CD11b allowing for differentiation of lymphocyte, macrophage and microglial populations (A). Cells were also stained for stabilin-1, and cells expressing stabilin-1 were identified (B). Proportion of total macrophages at day 7 and 14 post injection which are positive for stabilin-1 (C), and expression levels measured with mean fluorescent intensity for stabilin-1 at day 7 and day 14 post injection (D) were determined. NI: Non-injected hemisphere, GL: glioma injected hemisphere.
