Generating CRISPR/Cas9 Mouse & Rat Models
The use of CRISPR/Cas9* genome editing for the creation of unique rat and mouse models of human disease has revolutionized the field, with many advantages including: time-savings, potential reduction in animal usage and overall cost effectiveness. However, creating custom CRISPR mice and rats also brings other considerations in terms of the potential for off-target effects, mosaicism and mutations, and possible drawbacks for creating more complex genome modifications.

HOW CRISPR ACCELERATES RESEARCH
CRISPR enables transgenic mice to be generated more quickly and more precisely than ever. The classical approach to editing a genome is effective, but slow. Using CRSPR to selectively introduce DNA damage and letting cells repair themselves naturally is faster. This method reduces the timeline from months or years to a matter of weeks.

NEW GENE EDITING TOOLS, FEWER ANIMALS?
The use of CRISPR/Cas9 to edit genomes is resulting both in reductions in the number of genetically altered animals and in increases. "In individual studies, there is a great opportunity for reduction," says one scientist. She calls for "an increase in sophistication in genome editing... [and] in the sensitivity and reproducibility of in vivo phenotyping tests. Read the full story
