Large-Scale Differentiation of Human Induced Pluripotent Stem Cell-Derived Cardiomyocytes by Stirring-Type Suspension Culture

Regenerative medicine using human-induced pluripotent stem cells (hiPSCs) is a promising approach to treat heart failure. However, a large number of cells are required to achieve the desired therapeutic effect. The stirring-type suspension culture method allows a large-scale production of hiPSC-derived cardiomyocytes (more than 1 × 108 cells/100 mL), leading to a stable cell supply. Here, we describe a method to scale-up hiPSC-derived cardiomyocyte production with a high differentiation efficiency.
