Generation of three miR-122 knockout lines from a human embryonic stem cell line.

ABSTRACT

miR-122 is the most abundant miRNA in the human liver, accounting for 52% of the entire hepatic miRNome. Previous studies have demonstrated that miR-122 plays key roles in hepatocyte growth, metabolism, and homeostasis. Here, we created three miR-122 knockout human embryonic stem cell line lines, WAe001-A-7, WAe001-A-8, and WAe001-A-9, using the CRISPR/Cas9 technique. These mutated cell lines retained their pluripotency, in vitro differentiation potential, normal morphology, and karyotype.
