Scientists used gene editing to make 69 genetic edits to a pig, including knocking out three pig genes and inserting seven human genes.
Previous attempts with unmodified pig livers failed within hours, but the pig livers with genetic edits in the Penn study showed stable blood flow and no signs of inflammation. [ more ]
