PDF file - 42K, Figure S2. Glioma-derived soluble factors can further induce B7-H1 expression in non-autologous GBM patient peripheral monocytes, but not in autologous patient monocytes. Quantification of mean fluorescence intensity for B7-H1 staining measured by flow cytometry is shown for monocytes stimulated with IL-10 (10 ng/ml) or glioma-conditioned media (SF1U-CM). In monocytes from healthy control patients, B7-H1 intensity was significantly increased by IL-10, and further increased by conditioned media (* p
