PARIS--(BUSINESS WIRE)--A new method for making precise changes in selected genes is taking the world of biomedical research by storm. Known by the rather inelegant name of CRISPR-Cas9, it is a rapid, efficient, versatile and relatively cheap tool for dissecting the molecular pathways that are the basis of life, as well as for investigating and potentially rectifying faults in these pathways that result in disease. During this Colloque Médecine et Recherche in Neurosciences organized by the Fondation Ipsen, an international panel of speakers reviewed how this and other genome editing techniques are advancing understanding of the development and functioning of the nervous system.
