Very good news for the branch of regenerative medicine that attempts to mimic the ability of certain lizards to regenerate entire body parts. The Australian reports that researchers 'have created 'miracle mice' that can regenerate amputated limbs or damaged vital organs, making them able to recover from injuries that would kill or permanently disable normal animals. 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.' It appears that this is 'controlled by about a dozen genes. Professor Heber-Katz says she is still researching the genes' exact functions, but it seems almost certain humans have comparable genes.' Wow. Full details to be presented at the SENS conference.
