ApoA-I and apoE increase the migration of MCF-7 cells but decrease that of MDA-MB-231 cells. a Migration curve of the different MCF-7 cell lines. b Migration rate of the different MCF-7 cell lines. c Migration curve of the different MDA-MB-231 cell lines. d Migration rate of the different MDA-MB-231 cell lines. Migration was obtained by creating a gradient of 1 (top well) to 10% (bottom well) serum. Migration was measured by impedance measurements (xCELLigence) in real-time (a, c), and migration rate was then determined between the dashed lines for each cell line (c, d). Significant difference compared to control cells: *P < 0.05
