  • Publication number: 20210123017
    Abstract: An object of the present invention is to provide a method for preparing dopamine neurons efficiently in a short period of time. The dopamine neuron is prepared by step of culturing pluripotent stem cells in the presence of a TGF-? family inhibitor, a GSK3? inhibitor, and a BMP inhibitor; step of suspension-culturing the cells obtained in step in the presence of a TGF-? family inhibitor, a GSK3? inhibitor, FGF8, and a hedgehog signal agonist and under normal oxygen partial pressure to form a neurosphere; and step of collecting the neurosphere to induce differentiation of the cells into dopamine neurons.
