WormMine: ExpressionPattern Expr1509

• Pattern: After induction by 0.1 mM CdCl2, intense staining of intestinal cell nuclei was observed in all developmental stages. In L1, all 20 intestinal cells was stained No staining was observed in any other cells. Expression was maximal in the four cells that surround the anterior of the intestinal lumen. The intensity of beta-gal staining declined steadily in the succeeding pairs of cells that constitute the central and posterior portion of intestine. In uninduced animals, mtl-2 was inactive in all cells.

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
