In histology, an intestinal crypt, also crypt of Lieberkühn and intestinal gland, is a gland found in the epithelial lining of the small intestine and colon.

The crypts secrete various enzymes, including sucrase and maltase, along with endopeptidases and exopeptidases. Also new epithelium is formed here, keeping in mind that the epithelium at this site is frequently worn away by the passing food. Loss of proliferation control in the crypts is thought to lead to colorectal cancer.

The basal portion of the Crypt contains multipotent stem cells. At each mitosis one daughter remains a stem cell while the other differentiates and migrates up the side of the crypt and eventually the villus. Goblet cells are among the cells produced in this fashion.

Pathologic processes that lead to chronic, i.e. on-going, intestinal crypt destruction are associated with branching of the crypts.

Causes of crypt branching include:

Crypt inflammation is known as cryptitis and characterized by the presence of neutrophils between the enterocytes. A severe cryptitis may lead to a crypt abscess.

Eponym

The eponymous term (crypts of Lieberkühn) is named after the 18th-century German anatomist Johann Nathanael Lieberkühn.
