Methods for generating human committed midbrain neural stem cells (NSCs) and midbrain neural progenitor cells (midbrain NPCs) from human pluripotent stem cells are provided using chemically-defined culture media that allow for generation of the midbrain NPCs in as little as six days. The midbrain NPCs can be further differentiated to mature dopaminergic neurons. Culture media, isolated cell populations and kits are also provided.

The present invention relates generally to the field of cell biology of stem cells, more specifically the directed differentiation of pluripotent or multipotent stem cells, including human embryonic stem cells (hESC), somatic stem cells, and induced human pluripotent stem cells (hiPSC) using novel culture conditions. Specifically, methods are provided for obtaining neural tissue, floor plate cells, and placode including induction of neural plate development in hESCs for obtaining midbrain dopamine (DA) neurons, motor neurons, and sensory neurons. Further, neural plate tissue obtained using methods of the present inventions are contemplated for use in co-cultures with other tissues as inducers for shifting differentiation pathways, i.e. patterning.

Methods of generating spinal cord glutamatergic interneurons (V2a interneurons) from human pluripotent stem cells (hPSCs) are provided. A method of the present disclosure may include culturing a first population of hPSCs in vitro in a neural induction medium that includes: a retinoic acid signaling pathway activator; a sonic hedgehog (Shh) signaling pathway activator; and a Notch signaling pathway inhibitor, wherein the culturing results in generation of a second population of cultured cells containing CHX10+ V2a interneurons. Also provided are non-human animal models that include the hPSC-derived spinal cord glutamatergic interneurons, and methods of producing the non-human animal models.
