摘要: Human pluripotent stem cells (PSCs) are a promising cell resource for various applications in regenerative medicine. Highly efficient approaches that differentiate human PSCs into functional lineage-specific neurons critical modeling neurological disorders and testing potential therapies. Proneural transcription factors crucial drivers of neuron development hold promise driving highly neuronal conversion PSCs. Here, we study the functions proneural factor Atoh1 differentiation We show is induced during ectopic expression sufficient to drive with high efficiency. induction, combination extrinsic factors, differentiates dopaminergic (DA) >80% purity. Atoh1-induced DA recapitulate key biochemical electrophysiological features midbrain neurons, degeneration which responsible clinical symptoms Parkinson's disease (PD). provide reliable model studying PD pathogenesis, such as neurotoxin-induced neurodegeneration PD. Overall, our results determine role regulating subtype specification Our Atoh1-mediated approach will enable large-scale patient-derived mechanistic studies drug screening both familial sporadic
