Pluripotent markers such as Oct3/4 and Tra‐1‐60 were expressed in embryoid bodies 2 weeks after differentiation in the massive suspension culture system. Metabolic purification of cardiomyocytes (CMs) in glucose‐depleted and lactate‐enriched medium successfully eliminated residual undifferentiated stem cells, resulting in a refined CM population. Purified CMs never induced teratomas, and enriched CMs showed proper electrophysiological properties and calcium transients.
