It takes far more expertise, however, to remove dozens of PERV genes at once, as eGenesis does in
pig fibroblasts, which are connective - tissue
cells.
To further facilitate genome editing in
pigs, we report here establishment of a
pig line with Cre - inducible Cas9 expression that allows a variety of ex vivo genome editing in
fibroblast cells including single - and multigene modifications, chromosome rearrangements, and efficient in vivo genetic modifications.
