摘要

Provided is a method for maturing a cardiomyocyte, whereby it becomes possible to obtain a maturated mature cardiomyocyte. One component selected from the group consisting of a specific nuclear receptor agonist, a maturation-promoting compound and a transcriptional factor capable of promoting the maturation of a cardiomyocyte or an arbitrary combination of these components is added to an immature cardiomyocyte. As a result, the immature cardiomyocyte can be matured to give a mature cardiomyocyte. Among the above-mentioned components, a nuclear receptor agonist is one component selected from the group consisting of a hormone, an RXR agonist, a PPAR agonist and an ROR agonist or an arbitrary combination of these components, and the maturation-promoting compound is an HIF1a inhibitor.
