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: WebMay 4, 2024 · These stomatal crypts are located only on the underside of the leaves, where they experience less sun exposure and therefore less water loss.

WebMar 1, 2014 · Myocardial crypts have been described within the LV wall of patients with HCM since early postmortem studies. 3 – 5 In particular, to the best of our knowledge, the first pathological description of a myocardial cleft dates back to 1958, in the historical publication of Donald Teare. 3 Noteworthy, Teare observed clefts not only at gross … WebCrypt formation originates within the basal part of the villi as new luminal structures form and extend into the underlying mesenchyma and eventually fuse with the intestinal lumen by an upward migration. Initially, cell proliferation occurs along most of the luminal epithelium, but once villi form it is restricted to the intervillus spaces.
WebMay 18, 2009 · The epithelium of the small intestine and colon is the most rapidly self-renewing tissue in mammals.
