WormMine: ExpressionPattern Expr1489

• Pattern: Expression patterns of a translational lacZ fusion including most of the gene (PGSAL) was similar to those of the promoter fusion (LF-1). In adult and larval hermaphrodites, many neurons and muscle cells show expression of the reporter. These include neurons in the nerve ring, the ventral nerve cord, and the tail ganglia. Muscles expressing reporters include body wall muscles, the specialized muscles of the pharynx, and the vulva. In the male, male-specific neurons and muscle cells in the tail show the expression. Many epithelial cells in the pharynx and some vulva cells also express the reporter. No expression was observed in hypodermal cells or intestinal cells. Transgenes show similar expression pattern throughout larval development and in adult. The reporter is expressed in embryos at the comma stage and later stages.

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
