Figure 6. Cell-type specific basal levels of metabolism and cell layer impedance.

Basal level of oxygen consumption, acidification of medium, and cell impedance recorded in the cell biosensor chip without drug treatment and at the beginning of experiments before treatment with cisplatin; A, basal respiratory activity (change of oxygen of medium); B, basal glycolytic rate (change of extracellular pH); C, relative difference of electrical capacity in comparison to cell-free biosensor chip.
