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.
View ArticleGenetic factors shaping salamander tails determine regeneration pace
Salamanders' capacity to regrow lost limbs may seem infinite when compared with that of humans, but even amongst salamanders, some species regenerate body parts very slowly, while others lose this...
