Contractile force measurement of cardiac cell sheet-tissues.
(A) A representative contractile force trace of a cardiac cell sheet-tissue. (B, C) Time course analysis of contractile forces (B) and beating rates (C) of cardiac cell sheet-tissues for 6 hours. Each value of contractile forces at a certain time point was determined as the mean of those values in one minute just before that time point. Each value of beating rates at a certain time point was determined as the number of beatings in one minute just before that time point. Results are presented as mean ± SD for 5 cardiac cell sheet-tissues. Among the 5 cardiac cell sheet-tissues, 2 samples were prepared from a same differentiation batch. The other 3 samples were prepared from different 3 differentiation batches respectively.
