Figure 7. Macrophages promote SOX9-dependent migration in lung cancer cells.
SOX9 expression was inhibited in A549 cells via RNAi. (A) Migration ability was examined in a wound healing assay 48 hours after macrophage supernatant was added to A549 cells or after co-culture of macrophages with A549 cells. (B) Mean migration distance of the wound edge after macrophage supernatant was added to A549 cells or after co-culture of macrophages with A549 cells. ***p < 0.01, mean ± SEM.
