Piptadeniastrum africanum stem bark extract (PASB) significantly inhibited the migration of MCF-7 cells after 24, 48 and 72 h. (A) Cell migration was calculated and expressed as the percentage of the “wound” area covered by the cells to the initial cell-free “wound” area after treatment with either solvent control (0.1% DMSO) or PASB at concentrations of 0.5 x GI50 and 1 x GI50. The assay was repeated at least three different times. Bar and error bars represent mean ± SD. ****p < 0.0001 vs control. (B)The representative images of the migratory cells were taken under an inverted microscope at 10X objective
