Cells on the inner surface of the intestine are replaced every few days. But, how does this work? It was always assumed that cells leave the intestinal surface because excess cells are pushed out. In ...

In a recent review published in the journal Frontiers in Medicine, a group of authors explored the relationship between intestinal stem cells (ISCs) and the gut microbiota and their role in ...

A new study reveals that age-related changes in the gut microbiota directly impair intestinal stem cell (ISC) function and that restoring a youthful microbial environment can reverse this decline.

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 intestinal parasite Cryptosporidium is a vicious trespasser, hiding within the cells that line the gut and causing intestinal damage. "Cryptosporidium infections can be life-threatening, ...

Tuft cells are present throughout the intestinal tract as well as in many organs. Studies in mice have shown that when tuft cells sense the presence of pathogens, they signal to immune cells and to ...

The capacity of intestinal stem cells to maintain cellular balance in the gut decreases upon aging. Researchers have discovered a new mechanism of action between the nutrient adaptation of intestinal ...

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 ...
