Mouse regrows limbs and internal organs

From the Sunday Times (London):

SCIENTISTS have created a “miracle mouse” that can regenerate amputated limbs or badly damaged organs, making it able to recover from injuries that would kill or permanently disable normal animals

The researchers have also found that when cells from the test mouse are injected into ordinary mice, they too acquire the ability to regenerate.

The discoveries raise the prospect that humans could one day be given the ability to regenerate lost or damaged organs, opening up a new era in medicine.

Details of the research will be presented next week at a scientific conference on ageing, Strategies for Engineered Negligible Senescence, at Cambridge University. Ellen Heber-Katz, professor of immunology at the Wistar Institute, an American biomedical research centre, says that the ability of mice at her laboratory to regenerate appears to be controlled by about a dozen genes.

She is still researching their exact functions, but it seems almost certain that humans have comparable genes.

The researchers suspect that the same genes could confer greater longevity and are measuring the animals’ survival rate. The mice are, however, only 18 months old and the normal lifespan is two years so it is too early to reach conclusions.

The implications are mind-boggling.

  1. It’s a great time to be alive, isn’t it! More and more, my collection of pulp science fiction has been eclipsed by reality. (The stories are still fun to read, even if the ideas therein aren’t astounding anymore, just quaint.)
