Combined S100A9, CD14 and HLA-DR analysis on peripheral blood mononuclear cells (PBMC) and whole blood cells from patients with colon cancer. Fresh isolated PBMC or whole blood lysate from 10 colon cancer patients are stained with CD14, HLA-DR and S100A9. Gates are set on the upper/lower 10% of S100A9/HLA-DR cells. (a) S100A9 expression is compared between CD14⁺ HLA-DR^−/low MDSC (grey bar) and CD14⁺ HLA-DR⁺ monocytes (white bar). *P < 0·05. (b) HLA-DR expression is compared between CD14⁺ S100A9^high (grey bar) and CD14⁺ S100A9^low (white bar) cells. *P < 0·05.
