Fig 4

A,B. Wound healing assay. A549 cells were treated with CTEO and artificial scratches were done with sterile 200 μL pipette. Photographs were taken after treatment. C,D. Transwell invasion chamber assay. The cells were treated the concentration indicated by CTEOfor 48 h. Cells invading the basement membrane were stained with Giemsa. Values represent mean ± SD of three independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001 compared with the untreated control (dose 0).
