Wired PR News.com – Scientists in Japan have successfully cloned mice that had been frozen for more than a decade, and may one day use their methods to resurrect extinct species, as reported by Reuters.
The experiment took place at the RIKEN research institute in Yokohama, Japan. Teruhiko Wakayama, a mouse-cloning expert, played a role in the experiment along with fellow scientists from the Center for Developmental Biology. The cloning was reportedly successful despite the damage that had occurred with the cells of the mice, which had been frozen for 16 years.
The researchers wrote in the Proceedings of the National Academy of Sciences that the results could have implications for further resurrection or cloning efforts of animals or the ability to take samples from frozen tissue. The scientists were stated to have carried out the experiment using a nuclear transfer technique, which involves nucleus replacement in cells. The transfer may one day prove to be a way to help preserve species that are endangered.
Cloning is a method many doctors hope will be successfully applied to human medicine in the future.
