  • Method for manufacturing peripheral nerve cells
    Patent number: 11499138
    Abstract: Provided is a method for efficiently manufacturing high-purity peripheral nerve cells from undifferentiated cells. The method for manufacturing peripheral nerve cells from undifferentiated cells having an ability to differentiate into peripheral nerve cells includes the following steps (a) and (b): (a) culturing undifferentiated cells having an ability to differentiate into peripheral nerve cells to induce differentiation into neural progenitor cells without detaching a grown colony from a culture vessel; and (b) detaching the neural progenitor cells produced in the step (a) from the culture vessel, then seeding the cells at a seeding density of 2×105 to 6×105 cells/cm2 to a culture vessel, and culturing the cells for 14 to 42 days.
    Type: Grant
