Some animals can regrow entire limbs after injury, rebuilding bone, muscle, nerves, and skin as if the damage never happened.

Losing a limb or an organ is life-altering for most creatures, but not for all. Some animals have evolved regeneration skills that go far beyond healing scrapes or broken bones. These species can ...

A wide variety of distantly-related animals, including flatworms, newts and zebrafish, have robust abilities to regenerate damaged or missing body parts. A new study shows little evidence of a common ...

Skeletal muscle stem cells in hibernating Syrian hamsters preserve their ability to function by suppressing their activation ...

Northwestern University scientists have developed a cell-free bioactive material comprising a complex network of molecular components that work together as a scaffold to mimic cartilage’s natural ...

Researchers have found a genetic pathway that facilitates inter-species communication between a marine worm, acoel, and its symbiotic algae. Many organisms are far more complex than just a single ...

It sounds like science fiction: Lose an arm and grow one back. But it isn't as crazy as it sounds. That's what crabs, lobsters and crayfish do. What's more, some flatworms can grow a new head and tail ...

Intestinal Stem Cells (ISCs) derived from a patient's own cells have garnered significant attention as a new alternative for treating intractable intestinal diseases due to their low risk of rejection ...

New research shows hibernating mammals protect muscle stem cells by suppressing activation, inflammation, and regeneration during cold, inactive periods.
