Monkeys are important for modeling diseases because of their close similarities to humans, but past efforts to precisely modify genes in primates have failed. In a study published by Cell Press January 30th in the journal Cell, researchers achieved precise gene modification in monkeys for the first time using an efficient and reliable approach known as the CRISPR/Cas9 system. The study opens promising new avenues for the development of more effective treatments for a range of human diseases.
