Intestinal cells can change specializations during their lives. The BMP signaling pathway – an important communication mechanism between cells – appears to be the driver of these changes. That is wat ...

A research team led by scientists from the State University of Campinas (UNICAMP) in São Paulo, Brazil, has made significant progress in understanding the relationship between gut microbiota and ...

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 ...

In a recent study published in Science Advances, researchers used an organ-wide approach to quantitatively analyze cell number, size, and identity regulation upon nutrient-induced tissue adaptation of ...
