The effect of PFE on migration ability in human endometriotic cells. Human endometriotic 11Z (A) and 12Z (B) cells were seeded in uncoated chambers for migration assay in the presence or absence of PFE (25, 50, 100 μg/mL). Migrating cells were quantified using an inverted microscope as described in Materials and Methods. The columns represent the mean of three individual experiments performed in triplicate; bars, SD. * p < 0.05.
