Generation and characterization of a human iPSC line expressing EGFP-tagged CDH1, KSCBi002-A-3

초록

E-cadherin, a transmembrane protein, is essential for maintaining the integrity and structure of human pluripotent stem cells (hPSCs) by facilitating strong cell-cell adhesion and communication, which is crucial for their colony formation and pluripotency. Here, we used the CRISPR/Cas9 system to introduce the enhanced green fluorescent protein (EGFP)-tagged CDH1 into the AAVS1 locus, a safe harbour site, of human induced pluripotent stem cells (hiPSCs). The engineered cell line, KSCBi002-A-3, expressed functional CDH1-EGFP fusion protein, exhibited normal cell morphology, maintained a normal karyotype, and retained pluripotent state.
