WormMine: ExpressionPattern Expr138

• Pattern: Diffuse expression of intestinal precursor cells at various embryonic stages. Diffuse intestinal expression in an L2 larva. Diffuse intestinal expression is observed from the embryonic lima bean stage through elongation and into early larval stages. In adult stages expression is seen in components of the intestino-rectal valve. Diffuse expression is also seen in the hypodermis of the tail spike. Expression is seen in components of the adult intestino-rectal valve and some diffuse expression in the tail spike.
• Primary Identifier: Expr138
• Remark: Other strain-- UL693

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
