Salt Lake City, UT – In the 1980's, University of Utah geneticist Mario Capecchi developed gene targeting technology, which allows scientists to tailor mutations in specifric genes. Researchers around the world use it to manipulate mouse DNA. With this tool, scientists at the University of Utah have recently created a mouse with a deadly form of childhood muscle cancer. Sheri Quinn reports on how this new mouse model might help fight the disease.
