Double immunofluorescent staining for CD68 and M1 macrophage marker (NOS2, CXCL10 or CD11c) or M2 marker (CD163, CD206 or CD115) at the IF of serial sections from the same CRC clinical sample. A, The representative immunofluorescent staining images of IF samples (scale bar 50 μm). B, The ration with positive CD163, CD206, CD115, NOS2, CXCL10 and CD11c in CD68⁺ macrophages at IF in CRC tissue. C, The number of CD68⁺ CD163⁺, CD68⁺ CD206⁺, CD68⁺ CD115⁺, CD68⁺ NOS2⁺, CD68⁺ CXCL10⁺, CD68⁺ CD11c⁺ cells at IF in CRC tissue.
