Generation of a KCNJ11 homozygous knockout human embryonic stem cell line WAe001-A-12 using CRISPR/Cas9.

The ATP-sensitive potassium channel is an octameric complex, and one of its subunits, namely Kir6.2, is encoded by the KCNJ11 gene. Mutations in KCNJ11 result in hyperinsulinism or diabetes mellitus, associated with abnormal insulin secretion. Here, using CRISPR/Cas9 editing, we established a homozygous mutant KCNJ11 cell line, WAe001-A-12, which was generated by a 62-bp deletion in the coding sequence of the human embryonic stem cell line H1. It was confirmed that this deletion in the KCNJ11 gene did not affect the protein expression levels of key pluripotent factors. Additionally, normal karyotype and differentiation potency were observed for the cell line.
