Generation of an inducible dCas9-SAM human PSC line for endogenous gene activation.

ABSTRACT: The CRISPR/Cas9 system has transformed genome editing by enabling precise modifications for diverse applications. Recent advancements, including base editing and prime editing, have expanded its utility beyond conventional gene knock-out and knock-in strategies. Additionally, several catalytically dead Cas9 (dCas9) proteins fused to distinct activation domains have been developed to modulate endogenous gene expression when directed to their regulatory regions by specific single-guide RNAs. Here, we report the development of the H9 human pluripotent stem cell (hPSC) line expressing an inducible dCas9-SAM activator (H9-iCas9.SAM), designed to activate transcription of endogenous genes. The H9-iCas9.SAM cells were generated through targeted integration of an inducible CRISPR/Cas9-based gene a
