Generation of stable Cas9-EGFP expressing human induced pluripotent stem cell lines based on SeLection by Essential-gene Exon Knock-in technology

Year: 2025

Type: article

Abstract: Here, we used SeLection by Essential-gene Exon Knock-in technology to generate the iPSC line with constitutive expression of Cas9-EGFP, while retaining all functions of the essential gene. Cas9-EGFP was inserted into the GAPDH exon9 via the homologous recombination, avoiding Cas9 silencing that often occurs during iPSC differentiation. The edited cell line shows precise knock-in locus with the typical characteristics and pluripotency of iPSCs. Therefore, this iPSC line is valuable for CRISPR screening or related experiments and could be widely used in the CRISPR/Cas9-based gene editing.
