WormMine: ExpressionPattern Expr3994

• Pattern: All reporters show qualitatively similar expression patterns. In transgenic embryos, gfp expression is detected in the developing gut by the comma stage and up to the 2-fold stage. By the late 3-fold stage of embryogenesis, dig-1 reporter constructs become strongly expressed in mesodermal cells. In larvae of all stages and adults, dig-1 reporter genes remain strongly expressed in mesodermal cells, including body wall, head, vulval, uterine, pharyngeal muscles, and in enteric and anal depressor muscles. Additional mesodermal cells expressing the dig-1 reporter construct include support cells in the head (GLR cells), the head mesodermal cell, coelomocytes and sex myoblasts. Expression could also be observed in the hypodermis. No expression could be observed in the nervous system.

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 single, H-shaped cell which lies just above the anus and connects the roof of the anal canal to the dorsal bodywall; its contractions act to increase the size of the anal opening by lifting the roof of the rectum and hence facilitate expulsion of intestinal contents.	anal depressor muscle	dilator muscle	WBbt:0004292

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
