US Patent 11473057 Method for obtaining microglia from pluripotent stem cells

The purpose of the present invention is to efficiently produce microglia from pluripotent stem cells. Provided is a method for producing microglia from pluripotent stem cells, comprising the following steps: (a) a step of co-culturing a pluripotent stem cell together with a feeder cell for 7 days or longer, and obtaining a blood progenitor cell; (b) a step of co-culturing the blood progenitor cell obtained in step (a) together with a feeder cell in the presence of IL-3 and/or GM-CSF, and obtaining an embryonic monocyte; and (c) a step of, in the presence of M-CSF, co-culturing the embryonic monocyte obtained in step (b) together with an astrocyte, or culturing the embryonic monocyte using an astrocyte supernatant.
