  • Method for reducing pluripotent stem cells, method for producing cell population having reduced pluripotent stem cells
    Patent number: 10711247
    Abstract: The present invention pertains to a method for culturing a cell population including pluripotent stem cells and differentiated cells derived from pluripotent stem cells at a temperature of 40.5° C. or higher and reducing the pluripotent stem cells included in the cell population. The present invention also pertains to a method for reducing pluripotent stem cells from a cell population including pluripotent stem cells and differentiated cells derived from pluripotent stem cells, wherein the method includes a step for activating the TRPV-1 expressed in the pluripotent stem cells included in the cell population. The present invention makes it possible to reduce the pluripotent stem cells remaining in an undifferentiated state when inducing the differentiation of a pluripotent stem cell population.
