(A) Pseudo-3D brightfield micrograph showing an all-human endothelialized myocardial tissue formed by seeding hiPSC-cardiomyocytes onto the bioprinted endothelialized scaffold after 15 days of pre-endothelialization. (B) Beating plots of the different local regions indicated in (A). Note that the contraction amplitudes were all normalized to the same height for easy comparison across the samples. (C, D) Relative beating of the endothelialized human myocardial tissues and the levels of vWF expression by the endothelial cells, respectively, upon treatment with different dosages of doxorubicin.
