TOKYO — A research team from the Institute of Physical and Chemical Science (Riken) has succeeded in cloning a mouse using tissue from a mouse frozen for 16 years.
The newborn mouse is the first animal in the world to be cloned from frozen animal tissue. The team’s work could potentially lead to the cloning of extinct animals such as mammoths, but likely will also prove controversial in terms of bioethics.
The research data appeared in Tuesday’s issue of the journal Proceedings of the National Academy of Sciences.
