However, Laurencin believes that if we are to reach the next level of 21st century medical advances, this puzzle must be solved. As well as using stem cells, regeneration can work by causing differentiated cells that had stopped dividing to 'go back' to dividing and multiplying in order to replace the lost tissue. In addition, researchers at Harvard Medical School found that a gene called Lin28a, which is active in immature animals (and humans), but shuts down with maturity, has a hand in enabling mice to regenerate tissue or at least to regrow the tips of their toes and ears. Their function is to stop infections and cause inflammation, which is the signal to the rest of the body that repair is needed. But they make for poor laboratory subjects.
