About the cover

On this week’s cover, a transgenic marmoset (Callithrix jacchus) containing the self-inactivating lentiviral vector CAG-EGFP. A team from seven Japanese institutions has generated transgenic marmosets in which the integrated transgene is transmitted through the germline and expressed in the offspring. This new non-human primate model, amenable to gene manipulation with transgenic technologies, should be invaluable for biomedical research into disease mechanisms and for developing therapies in gene therapy and regenerative medicine.
