Working On Advanced Regeneration
The Scotsman reports on a DARPA project to investigate regeneration of major organs and body parts. Lizards and many other animals can regenerate in this way, but humans have more limited capabilities (although even we can regenerate a 90% damaged liver). As one scientist says: "This is doable - I believe it is inevitable that we will regenerate an entire human limb." Whether or not it will happen through this methodology of investigating and replicating regeneration mechanisms in animals - rather than branches of regenerative medicine relating to stem cells or tissue engineering - remains to be seen.
