WormMine: ExpressionPattern Expr2414

• Pattern: pcrt-1GFP fusion protein is strongly expressed in many tissues throughout development and into adulthood, including intestine, uterus, pharynx, hypodermis, body wall muscle, and coelomocytes. Although some fluorescent neurons was observed in animals genetically mosaic for the pcrt-1GFP transgene, crt-1 did not appear strongly expressed in nervous system.
• Primary Identifier: Expr2414
• Remark: Reporter gene fusion type not specified. Weak signals in the nervous system might reflect the fact that the reporter construct, which lacks crt-1 introns and 3' untranslated regions, could be missing sequences critical for high level expression in neurons.

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

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
The organ in which the eggs are developed and protected until laid.	uterus		WBbt:0006760
Major cell type of nervous tissue, specialized for transmission of information in the form of patterns of impulses.	neuron	neurone	WBbt:0003679
A free-floating spherical cell lying in the pseudocoelomic cavity of larvae and adult C. elegans which can endocytose many compounds, possibly for immune surveillance. There are six coelomocytes in adult hermaphrodites, and they display prominent cytoplasmic inclusions and vacuoles.	coelomocyte		WBbt:0005751
