expert reaction to study looking at CRISPR and surrogate sires in livestock and mice

A study, published in PNAS, reports on a new method of utilising CRISPR techniques to produce surrogate sires in livestock and mice, for the potential use in breeding trait selection.  This Roundup accompanied an SMC Briefing.   Prof Dusko Ilic, Profesor of Stem Cell Science, King’s College London, said: “In this…

gene-edited livestock ‘surrogate sires’ successfully made fertile

Improving livestock to boost food production for a growing global population is a long-standing aim. For the first time, scientists have created animals that can serve as viable ‘surrogate sires’, male animals that produce sperm carrying only the genetic traits of donor animals. The researchers used CRISPR-Cas9 to produce mice,…
