WormMine: ExpressionPattern Expr1029

• Pattern: Expression is first detected in late gastrulation by the cephalic, inner labial, and outer labial cells. As the embryo elongates and morphogenesis begins, expression in body wall muscle cells is detected by in situ hybridization and is observed by using the GFP reporter. In addition, GFP is observed in the left and right lateral ALM neurons and the anal depressor and intestinal muscle cells. As embryogenesis continues, expression in the body wall muscle declines and is not observed in the larval stages. During the larval and adult stages, GFP expression by the PLM neurons, the intestinal cells, and the distal tip cells of the gonad is observed. In addition, transient expression is observed in HSN neurons during the L3 and L4 stages and in ventral nerve cord neurons during the early L2 stage.

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 single, H-shaped cell which lies just above the anus and connects the roof of the anal canal to the dorsal bodywall; its contractions act to increase the size of the anal opening by lifting the roof of the rectum and hence facilitate expulsion of intestinal contents.	anal depressor muscle	dilator muscle	WBbt:0004292
