CRISPR/Cas9-Based Safe-Harbor Gene Editing in Rhesus iPSCs.

ABSTRACT: NHP iPSCs provide a unique opportunity to test safety and efficacy of iPSC-derived therapies in clinically relevant NHP models. To monitor these cells in vivo, there is a need for safe and efficient labeling methods. Gene insertion into genomic safe harbors (GSHs) supports reliable transgene expression while minimizing the risk the modification poses to the host genome or target cell. Specifically, this protocol demonstrates targeting of the adeno-associated virus site 1 (AAVS1), one of the most widely used GSH loci in the human genome, with CRISPR/Cas9, allowing targeted marker or therapeutic gene insertion in rhesus macaque induced pluripotent stem cells (RhiPSCs). Furthermore, detailed instructions for screening targeted clones and a tool for assessing potential off-target nuclease activity are provided. © 2017 by John Wiley & Sons, Inc.
