In Vivo Editing of the Adult Mouse Liver Using CRISPR/Cas9 and Hydrodynamic Tail Vein Injection

Francesco Niola, Frederik Dagnæs-Hansen, Morten Frödin

    Abstract

    CRISPR/Cas9 technology allows facile modification of the genome in virtually any desired way through the use of easily designed plasmid constructs that express a gRNA targeting a genomic site-of-interest and Cas9. Hydrodynamic tail vein injection, on the other hand, is a simple method to deliver "naked" plasmid DNA to 5-40% of the hepatocytes of the liver of adult mice. Here, we describe how these two techniques can be combined to create a workflow for fast, easy, and cost-efficient in vivo genome editing of the adult mouse liver. Using this method, large cohorts of mice with genetically modified livers can be established within 3 weeks to generate models for gene function in normal physiology and diseases of the liver.
