Migration assays in three cell lines. (a) Wound healing assay to assess the effects of miR-20a-5p transfection on migration in the breast cancer cell lines SK-BR-3, MDA-MB-231, and MCF-7. Size bars indicate 100 µm. (b) The box plots represent the mean distance of migrated cells (µm ± SEM) in three independent experiments. *Significantly different from control.
