IA State Univ. Report 2012: Utility and Efficiency of Homologous Recombination for Introducing Targeted Modifications to the Pig Genome

The production and utilization of genetically modified animals greatly improves their utility in agriculture, as biomedical research models of human disease, for the production of recombinant pharmaceutical proteins, and for production of organs with greater potential for xenotransplantation. While numerous strategies have been utilized in the production of transgenic large animals, cell-based transgenesis followed by somatic cell nuclear transfer (SCNT) is currently the most widely applied method.
