WebAug 16, 2024 · Studies using either induced labeling or naturally occurring markers of stem cell lineage in mice and humans, respectively, have shown that intestinal epithelial cells leave the crypt and move up the villus in an orderly manner (2, 3).These migratory streams of cells can be observed as tightly arranged ribbons along the villus, indicating that … WebCrypt cells of the small intestine provide stem cells for renewal of the intestinal epithelium, which turns over each 3 to 4 days. Xenobiotics that target rapidly dividing cells result in epithelial villus atrophy. Specific biomarkers for small intestinal mucosal injury are limited.
