Electric stimulation of neonatal rat ventricular cardiomyocytes

ABSTRACT: Study on changes in gene expression in primary cultures of neonatal rat ventricular cardiomyocytes to electric stimulation. Through comparing non-stimulated, stimulated and blebbistatin supplemented and stimulated cultures we set out to identify the genes that are specifically activated by electric pulsing separate from cardiomyocyte contractions. Overall design: After initial recovery phase, primary cultures of neonatal rat ventricular cardiomyocytes were cultured for 3 days without pulsing, with electric pulsing or with electric pulsing combined with blebbistatin. Per treatment: 3 arrays, with samples obtained from 3 separate series of cardiomyocyte isolation and culturing. Per array: sample prepared from pooled (1:1) RNA from duplicate experiments.
