Figure 5 shows a confluent monolayer of viable cells in all the four groups and the control. This indicates that the majority of ADSCs were alive, with a mild reduction in cell viability in 200mV and 500mV. Based on these preliminary studies we chose 100mV/cm of DC ES for 15min per day for this experiment. In comparison to non-stimulated cells grown on plain silicon substrates, the stimulated cells showed slightly higher proliferation and hence a dense growth over a period of 3 days. The obtained results confirmed that electrical stimulation of ADSCs led to no significant cell viability loss.
