This chemically defined protocol facilitates the differentiation of human pluripotent stem cells (hPSCs) to highly pure neural stem cells (NSCs) characteristic of diverse anatomical regions throughout the posterior central nervous system (CNS). Whereas previous protocols generated NSC cultures of predominantly cervical spinal cord or heterogeneous regional identity, this protocol can generate NSCs with highly uniform (60-90% purity), distinct positional identity from discrete regions spanning the rostrocaudal neuraxis of the hindbrain thru cervical, thoracic, and lumbosacral spinal cord. The process relies on inducing colinear HOX activation in a pre-NSC culture by modulating Wnt/β-catenin, fibroblast growth factor (FGF), and growth differentiation factor (GDF) signaling. Then, the application of retinoic acid (RA) halts HOX activation and transitions the cultures to PAX6+ NSCs expressing HOX factors characteristic of specific hindbrain and spinal cord locations. Region-specific NSCs, which may have clinical utility, can be generated within 6-14 days depending on their rostrocaudal location.
