Observation of cell migration after exposure. Wound healing (a) and trans-well (b) assays were used to study cell migration. Migrated cells were quantified by capturing an average of 10 random fields from three independent duplicate experiments; the distance migrated by the cell monolayer to close the wounded area during this time period was measured. The migration index of each treatment, expressed as a value that related the distance traveled by treated cells to the distance migrated by untreated cells
