A major advance in solving a stumbling block of gene therapy -- how to safely and effectively deliver therapeutic DNA inside cells -- has been reported University of Wisconsin scientists.In what’s described as a remarkably simple solution, they used a system similar to that used for intravenous injection (IV) to inject genes and proteins into the limb veins of laboratory animals. The injected genetic material made its way to the animals’ muscle cells and functioned properly for an extended period.
