Titel:: Generation of heterozygous (MRli003-A-5) and homozygous (MRli003-A-6) voltage-sensing knock-in human iPSC lines by CRISPR/Cas9 editing of the AAVS1 locus.
Abstract:: Assessment of the electrophysiological properties of cardiomyocytes is necessary for phenotyping cardiac disorders and for drug screening. Optical action potential imaging using a genetically encoded voltage-sensing fluorescent protein (VSFP) allows for high-throughput functional characterization of cardiomyocytes, which offers an advantage over the traditional patch-clamp technique. Here, we knocked VSFP into the AAVS1 safe harbor locus of human iPSCs, generating two stable voltage indicator lines - one heterozygous (MRIi003-A-5) and the other homozygous (MRI003-A-6). Both lines can be used for optical membrane potential recordings and provide a powerful platform for a wide range of applications in cardiovascular biomedicine. «
