Figure 3. Comparison of the dielectric components of MCF-7 WT and MCF-7 DOX cells (mean ± SEM).

Figure 3

a) The resistant cells display a significant increase in Rextra compared to the wild type cells (p<0.0001). b) and c) The magnitude β of CPEcells and Rintra do not show significant alterations when the cells gain drug resistance. (n = 35 for MCF-7 WT and n = 21 for MCF-7 DOX cells, cell constant = 3660±50 m−1 and σmedium = 361 mS.cm−1, substrate: platinum).
