NFA inhibited the invasion and migration ability of CNE-2Z cells. A. Transwell Boyden chamber assays were performed to compare the invasion and migration potential of NFA at different concentrations. Cells after 48 h incubation at 200 × magnification. B. Quantitative results were shown as invasion and migration cells, which were calculated by 5 visual fields selected in the transwell migration and invasion assays (means ± SD, n=3, *P<0.05; **P<0.001).
