Abstract:Genetically engineered mouse models (GEMMs) that employ site-specific recombinase (SSR) technology are important tools for pre-clinical studies, but this approach is costly and time-consuming. Here, we show that the CRISPR/Cas9 system can be used to efficiently complement existing GEMMs of sarcoma and generate primary sarcomas in wild type mice. Mice with the genotype KrasLSL-G12D/+; Rosa26LSL-Cas9-EGFP/+ received intramuscular delivery of an adenovirus expressing Cre recombinase and a single guide RNA (sgRNA)… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
