A mouse injured on one leg experiences an "awakening" of stem cells in the other leg as if the cells are preparing to heal an injury. Something similar happens in axolotls, which are masters at limb ...

Why are so few species able to regenerate damaged or missing body parts, even though regeneration might seem an obvious survival advantage? Researchers at the Max Planck Institute (MPI) for ...

For example, annelids such as Platynereis dumerilii can regenerate entire parts of their posterior body after injury. The molecular mechanisms that control this process were hardly known until now. A ...

Regeneration is a hot topic in the sciences, and for good reason. We humans are not known for being great at regenerating, but if we could understand how other organisms do it so easily we might be ...

Regrowing a lost finger, hand or even an entire limb has long been considered impossible for humans.While salamanders and ...

The ability of metazoans (multicellular animals) to regenerate lost body parts varies greatly. Some animals can regenerate their whole bodies, including phyla Cnidaria such as jellyfish, ...

Whenever a jellyfish loses a tentacle, it can regenerate the lost limb. For years, scientists have been baffled by exactly how these ocean creatures bring their lost limbs back to life, but now we ...

A West Virginia University biologist is studying why some animals can regenerate while others cannot and has identified the genes that play a role in the process. Christopher Arnold, assistant ...
