Gene Editing with CRISPR/Cas9 (IMAGE) Universidad Carlos III de Madrid Caption The authors of this study have applied the gene-editing tool CRISPR/Cas9, which in this case is employed to safely and accurately eliminate from the stem cells of the skin of patients the exon 80 of the COL7A1 gene, which contains the pathogenic mutation. This leads to the production, from the edited cells, of a functional C7 variant Credit UC3M Usage Restrictions None License Licensed content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
