Wired has an article about the incredible ability of some altered mice to regenerate damaged tissue.
These mice have regenerated amputated digits, damaged heart, liver, and brain tissue and have even passed this newly acquired ability on to their offspring!!
Even more amazing, when researchers injected normal mice with cells from the mutant regenerators the normal mice gained the ability to regenerate!!
Looks like these mice are the first live version of the Marvel X-Men's Wolverine. Look out, Kitty...
