The present invention provides a method for inducing differentiation of cardiomyocytes efficiently and selectively from stem cells. A method for inducing differentiation of cardiomyocytes from pluripotent stem cells, which comprises: (i) culturing the pluripotent stem cells in a culture medium containing no substance that promotes activation of the canonical Wnt signaling pathway during the time period between initiation of differentiation induction and 24 hours before the period of elevated canonical Wnt gene expression; and then (ii) culturing the pluripotent stem cells in a culture medium containing a substance that promotes activation of the canonical Wnt signaling pathway during a time period of 24 to 96 hours, starting from 24 to 0 hours before the period of elevated canonical Wnt gene expression.

Method for inducing differentiation of pluripotent stem cells into cardiomyocytes

A novel growing method is provided for pluripotent stem cells such as ES cells. The method of the invention is a pluripotent stem cell growing method and gene transfer method in which pluripotent stem cells are cultured under conditions that maintain their undifferentiated state and pluripotency, the method being characterized by using a liquid medium and a culturing vessel having immobilized or coated on a substrate solid phase surface a molecule which is adhesive to the pluripotent stem cells in a fixed concentration, to grow the pluripotent stem cells in a dispersed state while maintaining their undifferentiated state and pluripotency, without using feeder cells, or to transfer and express a gene therein.

Pluripotent stem cell growing method

For a method of inducing differentiation of cardiomyocytes from stem cells, a method is provided to induce efficiently and selectively differentiation of cardiomyocytes by such a method in which the stem cells are cultured to induce differentiation into cardiomyocytes in the presence of a substance that inhibits BMP signaling.
