Induction of migration by macrophage CM. (A)A549 cells were incubated with monocyte or macrophage conditioned media (CM) for 24 h. Migration ability was determined using a wound healing assay. (B) Migrated cells were quantitated using a trans migration assay. Data are average values ± SD of at least five independent experiments. *** p < 0.001 (compared with Non-induced)
