An Episomal CRISPR/Cas12a System for Mediating Efficient Gene Editing.

ABSTRACT: (1) Background: Gene editing technology, as represented by CRISPR is a powerful tool used in biomedical science. However, the editing efficiency of such technologies, especially in induced pluripotent stem cells (iPSCs) and other types of stem cells, is low which hinders its application in regenerative medicine; (2) Methods: A gene-editing system, COE, was designed and constructed based on CRISPR/Cas12a and Orip/EBNA1, and its editing efficiency was evaluated in human embryonic kidney 293T (HEK-293T) cells with flow cytometry and restriction fragment length polymorphism (RFLP) analysis. The COE was nucleofected into iPSCs, then, the editing efficiency was verified by a polymerase chain reaction and Sanger sequencing; (3) Results: With the extension of time, COE enables the generation of up
