Generation of heterozygous KCNA2 knockout induced pluripotent stem cell line

Abstract

The KCNA2 gene is the voltage-gated ion channel from both functional and structural perspectives. KCNA2 is involved in diverse functions including the regulation of neurotransmitter release, heart rate, insulin secretion, neuronal excitability, epithelial electrolyte transport, smooth muscle contraction, and cell volume. To investigate the relevant pathophysiological mechanisms, we generated heterozygous KCNA2 knockout human induced pluripotent stem cell (iPSC) line via CRISPR/Cas9 gene editing. The generated iPSCs had a normal karyotype, were free of genetically integrated epitaxial plasmids, expressed pluripotency markers, and maintained trilineage differentiation potential.
