WormMine: ExpressionPattern Expr9809

• Pattern: GFP expression was observed from just before hatching to mature adult. Broad neuronal GFP expression was observed in the head and tail, but not in the ventral nerve cord. GFP was most prominent in the pharynx in larvae, in possibly all pharyngeal cells including muscle. The pharyngeal expression was fainter but still visible in the adult. GFP was also present in intestinal nuclei throughout development but again more faintly in the adult.

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
the feeding organ, a neuro-muscular pump in the head of the animal, used to ingest food, bacteria suspended in liquid, filter them out, grind them up and transport posteriorly into the instestine.	pharynx	esophagus	WBbt:0003681
neuron with its cell body situated in the head, excluding the pharynx.	head neuron		WBbt:0006751
