WormMine: ExpressionPattern Expr2233

• Pattern: When GFP expression was driven by the promoter sequences upstream of the NHX-2-coding sequences, fluorescence was found nearly exclusively in the intestine of the worm. The entire intestine was labeled evenly in the nhx-2::GFP transgenic animals. nhx-2::GFP labeling was strong in both L1 and L2 larval animals, then diminished with age.
• Primary Identifier: Expr2233

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
