M1 and M2 mobilization in the lung of signal transducer and activator of transcription 6 (STAT6)-deficient mice. (A,B) Fluorescent images of CD68 (green) and CD163 (red) in lung carcinoma and para-carcinoma tissues of WT and STAT6−/− tumor-bearing mice. (C) Flow cytometry analysis of M1 and M2 cells. (D–G). M1 and M2 cells in WT and STAT6−/− tumor-bearing mice. (D) Percentage of M1 cells (CD11b+ F4/80low Ly6ChighCD206−) in the blood. (E) Percentage of M2 cells in the blood (CD11b+ F4/80highLy6C−CD206+). (F) Percentage of M1 cells in the lung. (G) Percentage of M2 cells in the lung. (H) Relative mRNA expression of iNOS in CD11b+cells isolated from the lung. (I) Relative mRNA expression of Arg1 in CD11b+ cells directly obtained from mice. Total number of gated cells was 10 × 10E4. *P < 0.05, **P < 0.01, ***P < 0.001.
