WormMine: ExpressionPattern Expr13586

• Pattern: Expression begins in the metacorpus of the pharynx of late embryos and carries on through larval and adult stages. Faint intestinal, bodywall muscle and very strong tail expression, possibly the intestinal-rectal valve, in larvae and adults.
• Primary Identifier: Expr13586
• Remark: Strain UL1990, UL2564

Definition	Name	Synonym	Primary Identifier
A chain of very large cuboidal cells forming a wide central lumen in which food arrives from the posterior pharynx, is digested, and from which waste products proceed to the rectum. Intestinal rings form in groups of two and four cells surrounding the common lumen; thus the epithelium is only one cell deep at any point, with neighboring cells firmly secured to their neighbors by apical adherens junctions. These cells have very large nuclei and many large vacuoles, yolk granules, and other inclusions; the latter increase in number and electron density as the animal ages.	intestine	gut	WBbt:0005772
