Effects of PFOA on MCF-10A cell migration and invasion capacity. Effects of PFOA on MCF-10A cell migration (a) and cell invasion (b) by a transwell assay. Migrated or invaded cells in the bottom were fixed with 4% formaldehyde and stained with DAPI and counted as described in the “Material and methods” section. Values represent mean ± SD. Statistically significant differences from control are indicated as follows: ***p < 0.001 and **p < 0.01 (Student’s t test)
