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 ...

Gut support cells communicate with surprising precision – like brain neurons – using tiny extensions to send instructions to the stem cells responsible for maintaining and healing the intestine. The ...

Eating is one of life’s few constants: If you’re not eating right now, you’ll certainly be eating something within a few hours. But when and how often we should eat is still not fully understood.

Researchers have solved a cellular mystery that may lead to better therapies for colorectal and other types of cancer. A professor of pediatrics-developmental biology and an assistant professor of ...

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 ...

Our guts hold a kind of brain, known as the enteric nervous system; it is a network of neurons that extends throughout the walls of the gastrointestinal tract. This neural network can also function ...

Researchers have found that CAR T-cell therapy can help aging intestines heal by targeting senescent cells. In mice, it ...

By utilizing intestine-wide cell imaging, the researchers found that the nutrient adaptation of stem cell size and the resulting differentiation vary in different regions of the gut. "Our observations ...

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