Talking 'bout regeneration: How do some animals regrow missing parts?

By studying the genetic mechanisms that enable regeneration in our distant evolutionary cousins, scientists hope to one day uncover potentially latent healing abilities that may lie hidden in our own genome. Four professors are undertaking the basic scientific research needed to begin to answer these and other questions. Each of them approaches the problem from a different angle, focusing on different aspects of regeneration, and using different vertebrate models.
