Developments in genome-editing technology, especially CRISPR-Cas9, have revolutionized the way in which genetically engineered animals are generated. However, the process of generation includes microinjection to the one-cell stage embryo and the transfer of the microinjected embryo to the surrogate animals, which requires trained personnel. We recently reported the method includes introduction of CRISPR-Cas9 systems to the developing cerebral cortex via in utero electroporation thus generating gene-targeted neural stem cells in vivo. This technique is widely applicable for gene knockout, monitoring gene expression, and lineage analysis in developmental biology. In this chapter, the detailed protocol of EGFP (enhanced green fluorescent protein) knock-in method via in utero electroporation is described.
