A mouse digit does not usually grow back once it is amputated above the tip. It seals the wound, lays down scar tissue, and ...

Scientists have taken a surprising step toward unlocking regeneration in mammals, showing that the ability to rebuild complex ...

Stem cells play central roles in tissue homeostasis, regeneration, and repair across diverse biological systems. Advances in stem cell biology, lineage tracing, organoid and bioengineered models, and ...

Researchers have shed new light on how tissues in the body are repaired following the damage and premature death of tissue cells. As our bodies grow and develop, cells naturally die off where they are ...

Researchers at the University of Toronto have discovered that bacteria can drive stem cell regeneration to repair the intestinal lining after injury—uncovering an unexpected way in which the gut ...

The delicate balance between cell death and regeneration is crucial for human health and longevity. Most mechanisms involved in programmed cell death (PCD) play a key role in normal tissue renewal and ...

Cell plasticity, changes in cell fate, is crucial for tissue regeneration. In the lung, failure of regeneration leads to diseases, including fibrosis. However, the mechanisms governing alveolar cell ...

Scientists at the National Cancer Institute and partnering institutions have discovered that Schmidtea polychroa, a flatworm capable of regenerating lost tissue, develops this ability progressively ...

Researchers have uncovered a molecular pathway that appears to block kidney regeneration after injury. The body’s ability to ...

Regeneration sounds like a superpower. It is the ability to regrow lost tissues, organs, or limbs. Some creatures, like axolotls or starfish, do this effortlessly. Their bodies replace what was ...

Hair cells in the inner ear detect mechanical stimuli from sound waves and convert them into electrical signals that the brain can interpret. Some animals, such as zebrafish, can regenerate their ...

Scientists identify specific genes involved in zebrafish sensory hair cell regrowth, providing new insights that could inform future research into hearing loss treatments. While humans can regularly ...
