View ArticleSolving the mysteries of regeneration
Few animals can rival the amazing regeneration abilities of the flatworms known as planarians: When the worms' tails or heads are cut off, they grow new ones, and even a tiny piece of planarian tissue...
View ArticleTissue loss triggers regeneration in planarian flatworms
Unlike humans, planarian flatworms have the remarkable ability to regrow any missing body part, making them an ideal model with which to study the molecular basis of regeneration.
