Pigs which express tdTomato upon Cre or CRISPR editing of a genetic cassette inserted into their genome. (Pig analogue of Ai9 mice). This model system will aid translational preclinical studies for gene editing therapies.

A “turn-on” swine reporter model is developed to characterize local and systemic delivery of gene editors in vivo using viral or non-viral vectors. This adds the functionality of a reporter to preclinical gene delivery research in a large animal model that is more broadly accessible than nonhuman primates.
