  • Publication number: 20240384234
    Abstract: In related-art methods of differentiating pluripotent stem cells into a desired cell type, there has not been established a differentiation induction method using human ES/iPS cells and being highly efficient. Many attempts have been made, including a stepwise differentiation induction method based on the control of culture conditions or the addition of, for example, various cell growth factors/differentiation factors to a culture solution, but the use of complicated culture steps is a big problem. A method of inducing differentiation into a desired cell type within a short period of time and with high efficiency by use of a pluripotent stem cell that actively undergoes cell differentiation, which is obtained by reducing an undifferentiated state of the pluripotent stem cell, has been developed, and thus the present invention has been completed.
