WormMine: ExpressionPattern Expr2202

• Pattern: ver-1 was expressed in neural and muscular cell types localized in the anterior and posterior regions of the worm. The sheath, and very rarely the socket cells of the amphid and phasmid generally exhibited a bright fluorescence indicative of ver-1 promoter activity. In agreement with amphid sheath cell development, ver-1 expression was observed from the late embryonic stage to the adult, and for the phasmid sheath cells at the L1 stage, a stage when the cellular processes of the phasmid sheath cells are still lacking. They were identified by the channel they made for the chemosensory neurons after Dil dye filling. The ver-1 gene was upregulated at the dauer state. Beside these neural cell types, a frequent expression of the ver-1::gfp was observed in the muscular intestinal cell, which participates in the defecation process, and in the first and last intestinal cells, but rarely in other intestinal cells, indicating that this expression was not due to some unspecific expression by the gut.

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
a structural (glial) cell which forms an specialized environment surrounding the sensory ending(s) of one or more neurons; sometimes accompanied by a more distal socket cell. In early development of the sensory nerves and of the nerve ring some sheath cells (cephalics and labials) may also provide a substrate for axon guidance	neuronal sheath cell	pocket cell	WBbt:0005811
