WormMine: ExpressionPattern Expr2069

• Pattern: Extensive weak diffuse expression is seen in early and late stage embryos. In larvae and adults expression is still diffuse but more mosaic and is seen in a number of tissues, i.e. excretory cell, head ganglia, intestine, pharynx, and developing gonad.
• Primary Identifier: Expr2069
• Remark: Other strain-- UL1104

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
