WebJan 1, 2024 · The ISCs in the small intestine reside at the bottom of the crypt and each crypt hosts 12–16 ISCs (Snippert et al., 2010 ). The ISCs are interspersed with a similar number of post-mitotic Paneth cells that collectively constitute a bowl-shaped stem cell compartment that occupies the crypt bottom. ISCs divide about once every 24 h. 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.
