Effects of CIK combined with ATRA on cell migration (A) and invasion (B) of A549 and NCI-H520 cells. The wound closure percentage was measured using Axio Vison software. The cells on the lower chamber were calculated as invasion cells in 5 random fields of each group. The experimental data presented are mean ± SD from at least 3 independent experiments.*p < 0.05,**p < 0.01 compared with control groups, respectively. Δp < 0.05 compared with CIK or ATRA group, respectively.
