Temporal regulation of CRISPRi activity is critical for genetic screens. Here, we present an inducible CRISPRi platform enabling selection of iPSC-derived cardiomyocytes and reversible gene knockdown. We targeted a doxycycline-inducible dCas9-KRAB-mCherry cassette into the AAVS1 locus in an MYL7-mGFP reporter iPSC line. A clone with bi-allelic integration displayed minimally leaky CRISPRi activity and strong expression upon addition of doxycycline in iPSCs, iPSC-derived cardiomyocytes, and multilineage differentiated cells. The CRISPRi activity was validated by targeting the MYOCD gene in iPSC cardiomyocytes. In summary, we developed a robust inducible CRISPRi platform to interrogate gene function in human iPSC-derived cardiomyocytes and other cells. |
