WGBH Forum Network; Planarians: How to Regenerate a New Head in Under a Week

Planarians: How to Regenerate a New Head in Under a Week Peter Reddien, researcher, Whitehead Institute The human anatomy is no stranger to regeneration. If you think about all the times you have cut and scraped your hands, it's amazing how intact they are. Even more dramatic is the human liver: remove a chunk and it grows back. Researchers hope to one day harness the power of stem cells to regenerate, say, heart tissue, or pancreatic tissue, or nerve tissue. But at the moment, regeneration is still one of biology's greatest black boxes. In this discussion Whitehead scientist Peter Reddien discusses how he uses the planarian flatworm to study the mystery of regeneration.
