Mouse Models

Genetically engineered mouse models have been the workhorse of biomedical research and mammalian genetics for several decades. Traditional methods to genetically modify mice have been plagued by a plethora of problems such as low efficiency, high incidence of undesirable outcomes, random insertion or deletion of genes, and gene silencing to name a few. The advent of targeted gene editing technologies using nucleases (CRISPR/Cas9, ZFNs, TALENs) and recombinase (Cre, FLP, PhiC31 integrase), and has greatly improved site-directed mutagenesis and thereby enables the generation of more representative models of human diseases with increased efficiency, and faster turnaround.

Applied StemCell's uses two complementary gene editing technologies, CRISPR/Cas9 and the proprietary site-specific DNA integration platform, TARGATT™ to enable the generation of mouse models with a variety of gene modifications such as knock-in, knockout, point mutation, gene correction, reporter gene insertion, conditional knockout, gene overexpression models that are mimic the human condition better.
