Summary: Generation of CRISPR-Cas9-edited cortical neurons from human pluripotent stem cells (hPSCs) enables the study of gene functions and neural disease mechanisms. Here, we present a protocol for developing iCas9-iNgn2 hPSC, an inducible cell line that allows the simultaneous induction of the neuralizing transcription factor Ngn2 and the Cas9 nuclease to rapidly generate edited human cortical neurons. We describe the steps of the protocol from transducing iCas9-iNgn2 with guide RNA-containing lentivirus to producing edited cortical neurons in about 2 weeks.For complete details on the use and execution of this protocol, please refer to Dhaliwal et al.1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
