Researchers have found that muscle fibers in Japanese Fire-bellied Newts have an intrinsic ability to dedifferentiate, or reprogram, and contribute to limb regeneration. The results indicate that ...
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 ...
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, ...
An image of a planaria, a flatworm that can regenerate its entire body, under a fluorescent microscope. WVU research, led by biologist Chris Arnold, is looking at genes that lay the framework for ...
