SKOV-3 ovarian cancer cells are resistant to the effect of XFC in a wound-healing assay. (a) Photomicrographs of ES-2 and SKOV-3 cell migration, in the presence or absence of 60 μg/mL XFC, to the scratched zone at different time points (magnification, ×20). (b) Quantitative assessment of cells migrated into the scratched zone. For each condition, representative fields within the scratch were photographed. Data are representative of two independent experiments and are presented as a percentage of cell migration into the scratched zone in each culture medium group (control, 100%).
