Model of Murine Ventricular Cardiac Tissue for In Vitro Kinematic-Dynamic Studies of Electromagnetic and β-Adrenergic Stimulation

Quantitative immunofluorescence. After 48 h of culture, in comparison with control (CTRL), the isoproterenol (ISO) showed a significant prosarcomeric effect () and the electromagnetic stimulation (EMF) caused a significant antisarcomeric action (). The simultaneous use of pharmacological and physical stimulation (ISO + EMF) significantly reduced the effect of ISO (), giving an overall significant antisarcomeric action in comparison with CTRL (). The normalized data are expressed as mean fold ± 95% confidence interval ( cells for each condition).
