CRISPR/Cas9 system is a powerful genome-editing technology for studying genetics and cell biology. Safe harbor sites are ideal genomic locations for transgene integration with minimal interference in cellular functions. Gene targeting of the AAVS1 locus enables stable transgene expression without phenotypic effects in host cells. Here, we describe the strategy for targeting the AAVS1 site with an inducible Neurogenin-2 (Ngn2) donor template by CRISPR/Cas9 in hiPSCs, which facilitates generation of an inducible cell line that can rapidly and homogenously differentiate into excitatory neurons.
