Japan: Duplicate a mouse for nearly 600 children

Japanese scientists have created 581 perfect mice from only one after 25 replications, paving the way for the production of 'super' meat and milk in the lab.

Using the same technique as Dolly's sheep cloning technique, scientists have created identical mice, perfect both physically and "mentally".

Mice replicating 25 times still have normal health

They are fertile, have normal babies and live for about 2 years, just like normal mice. Dr. Teruhiko Wakayama, Development Biology Center Riken (Japan), said: ' The technique of duplicating mice can be very useful in large-scale production of super-high quality animals for the purpose of breeding or conservation '.

In an experiment that began eight years ago, Japanese researchers used body cell nuclear transmission (SNCT) to produce nearly 600 mice from the original mouse, after 25 consecutive replications.

The cloning technique began to be famous since 1997, when Dolly sheep, the first mammal was cloned from an adult cell, launched the world.

This technique is successfully used in the laboratory and for pets. However, after that, scientists promised to really overcome two major limitations: low success rates and difficulty replicating mammals.

Before the successful replication of mice 25 times in a row, attempts to replicate cats, pigs and mice more than twice failed.
