In Vitro Stomach?

Researchers have developed an advanced, long-term, 3-dimensional organoid culture system for primary, untransformed human gastric epithelium. The system, described in the January issue of Gastroenterology, provides evidence for the presence of stem cells in adult human gastric tissue and can be used to study changes that occur in the gastric epithelium during

How is Notch Activated in Intestinal Stem Cells?

The enzyme ADAM10 serves as a cellular scissors that clips and activates Notch in the intestine, required for subsequent cell lineage specification and intestinal stem cell survival, researchers report in the October issue of Gastroenterology. These Notch-activated stem cells appear to have a competitive advantage for replenishing the stem cell
