WormMine: ExpressionPattern Expr2938

• Pattern: GFP was observed from the embryo stage through to the adult stages. In the adult animal it was expressed in the pharynx, intestine, body wall muscle, gonad, distal tip cells and/or germ cells, nervous system, male tail rays, and spicule. chn-1 is probably expressed in all tissues.

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
Longitudinal bands of muscle cells surrounding animal body, with one band running in each quadrant of the body, regulated contraction and relaxation of these muscles cause locomotion.	body wall musculature	body muscle	WBbt:0005813
