Scientists at the Wistar Institute have discovered mice which can regenerate absolutely any tissue except for the tissues of the brain.
"The experimental animals are unique among mammals in their ability to regrow their heart, toes, joints and tail.
And when cells from the test mouse are injected into ordinary mice, they too acquire the ability to regenerate, the US-based researchers say.
Their 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."
That's freaking amazing!
