crypts of Lieberkühn

One common type of anatomical crypt is the Crypts of Lieberkühn.

Pocket-like invaginations into the underlying tissue are termed Crypts of Lieberkühn.

The J1 larvae penetrate the mucosa via the crypts of Lieberkühn in the distal ileum, cecum, and colon.

It is secreted from intestinal glands (the crypts of Lieberkühn) following the entry of ingested food passing from the stomach.

Proliferative cells (Stem Cells) reside in the crypts of Lieberkühn (epithelial invasions into the underlying connective tissue).

New cells are formed in the crypts of Lieberkühn which then migrate upwards and upon reaching the tip of the villus undergo apoptosis, getting shed off into the intestinal lumen.

The Crypts of Lieberkühn (intestinal glands) are named for him; he first described these in detail in De fabrica et actione vollorum intestinorum tenuium hominis, in 1745.

They are identified microscopically by their location just below the intestinal stem cells in the intestinal glands (AKA crypts of Lieberkühn) and the large eosinophilic refractile granules that occupy most of their cytoplasm.
