Gene Editing of Mouse Embryonic and Epiblast Stem Cells.

Efficient and reliable methods for gene editing are critical for the generation of loss-of-gene function stem cells and genetically modified mice. Here, we outline the application of CRISPR-Cas9 technology for gene editing in mouse embryonic stem cells (mESCs) to generate knockout ESC chimeras for the fast-tracked analysis of gene function. Furthermore, we describe the application of gene editing directly to mouse epiblast stem cells (mEpiSCs) for modelling germ layer differentiation in vitro.
