Figure 6. Engineered cardiac tissues fabricated and cultured within the milliPillar platform exhibit enhanced tissue function after 21 days of electrical ramp stimulation.

Figure 6.

(A) Ramp stimulation led to enhanced force generation measured at 1 Hz stimulation and PRP. (B) Contraction and relaxation velocities increased after electrical stimulation. (C) Positive FFR was observed in tissues after electrical stimulation. (D) Tissue excitability was enhanced after electrical stimulation. (E) Calcium transient durations decreased after electrical stimulation.
