Effect of ATRA on the random motility of breast cancer cells. Biological triplicates of the indicated luminal (MDA-MB-361, MDA-MB-175VII and HCC-1419; marked in red) and basal (MDA-MB-157; marked in blue) cell lines. Cells were pre-treated with vehicle (DMSO) or ATRA. Each point is the Mean + SD of 40 cells. ***Significantly lower than the vehicle curve (p < 0.001 following two-way ANOVA Bonferroni post-test)
