Figure 9. Macrophages promote SOX9-dependent tumorigenicity in lung cancer cells.

(A) Scramble control A549 cells or SOX9-knockdown A549 cells co-cultured with macrophages and control A549 cells cultured alone were subcutaneously injected into mice to form tumors. After three weeks, tumors were harvested and diameters were measured. (B) Tumor volumes in the different groups were quantified. ^***p < 0.01, mean ± SEM.
