Until now, doctors knew hepatic stellate cells mainly as drivers of liver fibrosis. The actual functions of this cell type have hardly been studied to date. Researchers have now determined that ...

A new study reported in Nature has determined that the amino acid cysteine could promote regeneration among cells in the small intestine. The work showed that cysteine can activate an immune signaling ...

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 ...

A diet rich in the amino acid cysteine may have rejuvenating effects in the small intestine, according to a new study from MIT. This amino acid, the researchers discovered, can turn on an immune ...

Memorial Sloan Kettering Cancer Center researchers have identified a metabolic switch that determines whether intestinal stem cells become absorptive or secretory cells. Manipulating the enzyme OGDH ...

The same genes could hold the key to regenerating cells in the ear and eye, according to a new mouse study from the USC Stem Cell laboratory of Ksenia Gnedeva, PhD, published in the Proceedings of the ...

The brain's mechanisms for repairing injuries caused by trauma or degenerative diseases are not yet known in detail. Now, a study from the University of Barcelona describes a new strategy based on ...

A new study has shown that alcohol intake can interfere with the natural regenerative abilities of the liver. Alcohol can keep cells in a kind of limbo between a functional or regenerative state, even ...

Thanks to three major grants, College of Arts and Science (CAS) faculty are leading groundbreaking research in lake ecosystems, membrane proteins, and tissue regeneration — advancing knowledge that ...

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 ...
