Effects of siRNA-EGFR on NSCLC cells' ability to migrate. NSCLC cells in control group showed higher motility in a standard scratch assay. The migration of A549 cells (upper) and SPC-A1 cells (lower) was quantitatively assessed at time points of 24 h (white) and 48 h (black) after the introduction of a scratch in monolayer transfected cells grown on collagen IV. Each column represented the mean of three experiments; bars, SD.
