Gene Editing: From Roots to Riches

October 3, 2016

(The Scientist) – In the mid-1980s, Oliver Smithies, then at the University of Wisconsin–Madison, and Mario Capecchi of the University of Utah independently used homologous recombination—a molecular process to repair broken DNA—to change specific regions of the genome in cultured mouse cells (Nature, 317:230-34, 1985; Cell, 44:419-28, 1986). The technique involved sandwiching an altered copy of a gene between two regions of code identical to those flanking the endogenous gene, which would be swapped out for its engineered counterpart.
