Deep in the folds of the intestine, in microscopic pockets called crypts, a quiet surveillance system is always at work. Stem cells lining the gut wall are not just rebuilding tissue—they are ...

When parts of the small intestine are diseased or die, the treatment can involve surgically removing the affected tissue.

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 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 ...

(Nanowerk Spotlight) The human digestive system presents a formidable challenge for medication delivery. Powerful stomach acids, protective barriers, and complex immune responses make it difficult for ...

Intestinal stem cells rejuvenate daily so bowels will stay healthy and function normally, but a new study in Cell Reports suggests they also age along with people and lose their regenerative capacity.

CAMBRIDGE, MA -- 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 ...

The terms "intestinal barrier" and "intestinal permeability" describe two different aspects of the same anatomical structure, the intestinal wall composed of four layers, the mucosa, the submucosa, ...
