Embryonic Stem Cell Targeting

In murine embryonic stem cells, the exchange of an endogenous allele of a target gene for a mutated copy via homologous recombination allows the generation of targeted ES cells with defined mutations in their genome. Genetically engineered ES cells remain pluripotent and are able to develop into germ cells in the chimeric animals, thereby ensuring germline transmission which results in a stable, genetically engineered mouse. As of today, this remains the most classic, reliable, and proven gene editing technology for mouse models.
