Straight talk with… Steve Brown

For decades, the study of gene function has relied heavily on the creation of ‘knockout’ mice, bioengineered to lack certain genes. But making a rodent without a specific gene is a chore—so much so that doctoral students sometimes dedicate their entire PhD work to generating a single mouse strain. The International Knockout Mouse Consortium (IKMC), launched in 2006, plans to change all that. The consortium, involving scientists from 33 research centers in nine countries, is creating a library of every gene knockout in embryonic stem cell lines, which can be used to produce mouse strains.
