A massive suspension culture system with metabolic purification for human pluripotent stem cell-derived cardiomyocytes.

ABSTRACT: Cardiac regenerative therapy with human pluripotent stem cells (hPSCs), such as human embryonic stem cells and induced pluripotent stem cells, has been hampered by the lack of efficient strategies for expanding functional cardiomyocytes (CMs) to clinically relevant numbers. The development of the massive suspension culture system (MSCS) has shed light on this critical issue, although it remains unclear how hPSCs could differentiate into functional CMs using a MSCS. The proliferative rate of differentiating hPSCs in the MSCS was equivalent to that in suspension cultures using nonadherent culture dishes, although the MSCS provided more homogeneous embryoid bodies (EBs), eventually reducing apoptosis. However, pluripotent markers such as Oct3/4 and Tra-1-60 were still expressed in EBs 2 weeks
