Human pluripotent stem cell (hPSC)-derived neural progenitor cells (NPCs), a multipotent cell population that is capable of near indefinite expansion and subsequent differentiation into the various cell types that comprise the central nervous system (CNS), could provide an unlimited source of cells for neural-related cell-based therapies and disease modeling. However, the use of NPCs for the study and treatment of a variety of debilitating neurological diseases requires the development of scalable and reproducible protocols for their generation, expansion, characterization, and neuronal differentiation. Here, we describe a serumfree method for the stepwise generation of NPCs from hPSCs through the sequential formation of embryoid bodies (EBs) and neuro-epithelial-like rosettes. NPCs isolated from neural rosette cultures can be homogenously expanded while maintaining high expression of pan-neural markers such as SOX1, SOX2, and Nestin. Finally, this protocol allows for the robust differentiation of NPCs into microtubule-associated protein 2 (MAP2) and β-Tubulin-III (β3T) positive neurons.
