Induction of hemogenic endothelium from pluripotent stem cells by forced expression of transcription factors

Described herein are methods and related compositions for inducing differentiation of human pluripotent stem cells (hPSCs) into hemogenic endothelium with pan-myeloid potential or restricted potential, by forced expression in the hPSCs of a combination of transcription factors as described herein.

Method for manufacturing peripheral nerve cells

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 2×10.sup.5 to 6×10.sup.5 cells/cm.sup.2 to a culture vessel, and culturing the cells for 14 to 42 days.
