WebMay 20, 2024 · Crypts are facing away from the intestinal lumen and sit in invaginations of the intestinal mucosa. They form pockets of approximately 44 μm in diameter and connect to the intestinal lumen only via a small opening (around 3 μm), due to dense packing of cells ( Maj et al., 2003 ). WebThe intestinal epithelium has a well-defined architecture. The simple columnar epithelium is folded to form a number of invaginations, the crypts (also called crypts of Lieberkühn or intestinal glands). In the small intestine, several crypts surround the base of finger-like projections towering into gut lumen called villi.
