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. Pathologic processes that lead to Crohn's disease, i.e. progressive intestinal crypt destruction, are associated with branching of the crypts. Causes of crypt branching include: WebIn between the villi are crypts (Crypts of Lieberkuhn) that invaginate down into the mucosa. The villi should be approximately 3 times the height of the crypts. The epithelium is intestinal type, which means goblet cells are interspersed among the tall columnar absorptive cells known as enterocytes.

WebThe crypt generates new cells that differentiate and migrate towards the tip of the villus. The crypt base columnar cells (blue) divide continuously and function as intestinal stem cells. Paneth cells (red) are also at the crypt bottom and nurse these stem cells.
