Contraction rates of engineered tissue constructs containing SIS gel (S; n = 3) were approximately twice those of constructs containing Matrigel (M; n = 3) between day 6 and day 11. *SIS gel constructs contracted at rates that were significantly closer to native rat myocardium55 compared to Matrigel constructs on days 8–11 (p < 0.01 on days 9 and 10, p < 0.05 on days 8 and 11, one-way analysis of variance with Tukey post-hoc test). Statistical comparison of groups was completed separately for each discrete time point. Time points for the two groups are staggered slightly for clearer presentation. Contraction rates are expressed in beats per minute (bpm).
