Effect of SCD4 deficiency on contractile properties of neonatal cardiomyocytes. A: Spontaneous beating rate of primary cardiomyocytes treated with stearic acid. B: Amplitude of cardiomyocyte contraction. C: Rising time (time for the cell index to increase from 10% to 90% of amplitude). D: Falling time (time for the cell index to decrease from 90% to 10% of amplitude). ^ap < 0.05, versus. WT control; ^bp < 0.05, versus WT 18:0. The data are expressed as the mean ± SD. n = 6–7 independent measurements.
