The key difference with experiments already carried out in China and US is that the research published by Nature last week doesn’t have embryonic gene therapy in view. The London Francis Crick’s Institute team, in fact, was not interested in correcting disease-causing mutations but in increasing knowledge on human embryonic development. We asked one of the authors, Alessandro Bertero, to explain goals and results. The Italian researcher was pursuing his Ph.D. at Cambridge when he helped to refine the technique used by Kathy Niakan and colleagues to edit the genome of embryos. He answered our questions via Skype from America, where he continues working on embryonic stem cells as a postdoctoral fellow at Washington University Continue reading
