Intracellular calcium trace from a representative PromoCell cardiomyocyte (Line A) that shows no intracellular calcium cycling upon stimulation after 4 weeks of differentiation. Red pulses represent the 10 ms 40 V pulse stimulation
Intracellular calcium trace from a representative PromoCell cardiomyocyte (Line A) that shows slow intracellular calcium transients upon stimulation after 4 weeks of differentiation. Red pulses represent the 10 ms 40 V pulse stimulation.
Intracellular calcium trace from a representative PromoCell cardiomyocyte (Line A) that shows occassional rapid intracellular calcium influx with slow efflux upon stimulation after 4 weeks of differentiation. Red pulses represent the 10 ms 40 V pulse stimulation.
