Causal mutations were identified in genes encoding for proteins of the desmosomes, predominantly plakophilin-2 (PKP2) and desmoglein-2 (DSG2). We generated gene-edited knock-out iPSC lines for PKP2 (JMUi001-A-2) and DSG2 (JMUi001-A-3) using the CRISPR/Cas9 system in a healthy control iPSC background (JMUi001A). Stem cell-like morphology, robust expression of pluripotency markers, embryoid body formation and normal karyotypes confirmed the generation of high quality iPSCs to provide a novel isogenic human in vitro model system mimicking ACM when differentiated into cardiomyocytes.}, language = {en} } @article{VitaleZoellerJanschetal.2021, author = {Vitale, Maria Rosaria and Z{\"o}ller, Johanna Eva Maria and Jansch, Charline and Janz, Anna and Edenhofer, Frank and Klopocki, Eva and van den Hove, Daniel and Vanmierlo, Tim and Rivero, Olga and Kasri, Nael Nadif and Ziegler, Georg Christoph and Lesch, Klaus-Peter}, title = {Generation of induced pluripotent stem cell (iPSC) lines carrying a heterozygous (UKWMPi002-A-1) and null mutant knockout (UKWMPi002-A-2) of Cadherin 13 associated with neurodevelopmental disorders using CRISPR/Cas9}, series = {Stem Cell Research}, volume = {51}, journal = {Stem Cell Research}, doi = {10.1016/j.scr.2021.102169}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-260331}, year = {2021}, abstract = {Fibroblasts isolated from a skin biopsy of a healthy 46-year-old female were infected with Sendai virus containing the Yamanaka factors to produce transgene-free human induced pluripotent stem cells (iPSCs). CRISPR/Cas9 was used to generate isogenic cell lines with a gene dose-dependent deficiency of CDH13, a risk gene associated with neurodevelopmental and psychiatric disorders. Thereby, a heterozygous CDH13 knockout (CDH13\(^{+/-}\)) and a CDH13 null mutant (CDH13\(^{-/-}\)) iPSC line was obtained. All three lines showed expression of pluripotency-associated markers, the ability to differentiate into cells of the three germ layers in vitro, and a normal female karyotype.}, language = {en} }
