Pluripotent stem cells provide a potential solution to current epidemic rates of heart failure by providing human cardiomyocytes to support heart regeneration. Studies of human embryonic-stem-cell-derived cardiomyocytes (hESC-CMs) in small-animal models have shown favourable effects of this treatment. However, it remains unknown whether clinical-scale hESC-CM transplantation is feasible, safe or can provide sufficient myocardial regeneration. Here we show that hESC-CMs can be produced at a clinical scale (more than one billion cells per batch) and cryopreserved with good viability. Using a non-human primate model of myocardial ischaemia followed by reperfusion, we show that cryopreservation and intra-myocardial delivery of one billion hESC-CMs generates extensive remuscularization of the infarcted heart. The hESC-CMs showed progressive but incomplete maturation over a 3-month period. Grafts were perfused by host vasculature, and electromechanical junctions between graft and host myocytes were present within 2 weeks of engraftment. Importantly, grafts showed regular calcium transients that were synchronized to the host electrocardiogram, indicating electromechanical coupling. In contrast to small-animal models, non-fatal ventricular arrhythmias were observed in hESC-CM-engrafted primates. Thus, hESC-CMs can remuscularize substantial amounts of the infarcted monkey heart. Comparable remuscularization of a human heart should be possible, but potential arrhythmic complications need to be overcome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4154594/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4154594/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chong, James J H -- Yang, Xiulan -- Don, Creighton W -- Minami, Elina -- Liu, Yen-Wen -- Weyers, Jill J -- Mahoney, William M -- Van Biber, Benjamin -- Cook, Savannah M -- Palpant, Nathan J -- Gantz, Jay A -- Fugate, James A -- Muskheli, Veronica -- Gough, G Michael -- Vogel, Keith W -- Astley, Cliff A -- Hotchkiss, Charlotte E -- Baldessari, Audrey -- Pabon, Lil -- Reinecke, Hans -- Gill, Edward A -- Nelson, Veronica -- Kiem, Hans-Peter -- Laflamme, Michael A -- Murry, Charles E -- P01 GM081619/GM/NIGMS NIH HHS/ -- P01 HL094374/HL/NHLBI NIH HHS/ -- P01GM081619/GM/NIGMS NIH HHS/ -- P01HL094374/HL/NHLBI NIH HHS/ -- P51 OD010425/OD/NIH HHS/ -- R01 HL084642/HL/NHLBI NIH HHS/ -- R01 HL117991/HL/NHLBI NIH HHS/ -- R01HL084642/HL/NHLBI NIH HHS/ -- T32 GM007266/GM/NIGMS NIH HHS/ -- U01 HL100405/HL/NHLBI NIH HHS/ -- U01HL100405/HL/NHLBI NIH HHS/ -- England -- Nature. 2014 Jun 12;510(7504):273-7. doi: 10.1038/nature13233.
