Human pluripotent stem cells hold great promise for improving regenerative medicine. However, a risk for tumor formation and difficulties in generating large amounts of subtype derivatives remain the major obstacles for clinical applications of stem cells. Here, we discovered that zinc finger E-box-binding homeobox 1 (ZEB1) is highly expressed upon differentiation of human embryonic stem cells (hESCs) into neuronal precursors. CRISPR/Cas9-mediated ZEB1 depletion did not impede neural fate commitment, but prevented hESC-derived neural precursors from differentiating into neurons, indicating that ZEB1 is required for neuronal differentiation. ZEB1 overexpression not only expedited neural differentiation and neuronal maturation, which ensured safer neural cell transplantation, but also facilitated the generation of excitatory cortical neurons, which were valuable for managing certain neurological disorders, such as Parkinson's disease (PD) and amyotrophic lateral sclerosis (ALS). Our study provides useful information on how human neural cells are generated, which may help in forming strategies for developing and improving replacement therapies for treating patients with neurological diseases.
