Figure 6. Detection of the number of migrating and invasive NCI-H1299 and A549 cells in each group by migration and invasion experiments. (A) Migration experiment shows the number of migrating NCI-H1299 and A549 cells (×400). **P < 0.01 means that the difference is statistically significant. (B) Invasion experiment reveals the number of invasive NCI-H1299 and A549 cells (×400). **P < 0.01 means that the difference is statistically significant.
