WormMine: ExpressionPattern Expr11584

• Pattern: Paakb-1::GFP is strongly expressed in pharyngeal muscles, the pharyngeal intestinal valve cells as previously noted and a few head neurons of the pharynx and the ring region. It is also detected in some support cells. Tail expression of Paakb-1::GFP includes the tail minor epithelium, the rectal-intestinal valve, posterior intestine and body wall muscles. Mid-body expression is mostly restricted to muscles of the vulva, uterus and body wall, but is also detected in the intestine. For a summary of Paakb-1::GFP see table S10.
• Primary Identifier: Expr11584

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
A group of six equivalent cells forms a tightly constructed `valve` that links the posterior bulb of the pharynx to the anterior four cells of the intestine. These six cells comprise a small epithelial channel with a cuticular lining in continuity with the pharyngeal cuticle and link the lumen of the pharynx to the large lumen of the anterior intestine.	pharyngeal-intestinal valve	cardia	WBbt:0005767
