WormMine: ExpressionPattern Expr2101

• Pattern: Expression is seen in larvae and adults, in a number of components. The first component consists of strong nuclear-localised expression in all intestinal cells. The second component consists of a number of neuronal nuclei located just anterior to the terminal bulb and associated with the nerve ring. The final component consists of weaker expression in cells around the somatic gonad that may be sheath cells of the gonad arms.

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

five pairs of thin gonadal sheath cells form a single layer covering the germ line component of each arm, each pair occupying a stereotyped position along the gonad proximal-distal axis.	gonadal sheath cell		WBbt:0005828
