Expression Pattern :

Pattern  Body wall muscle cells, hmc and MS.pppaaa show expression in early embryo. In later embryo through adulthood, stain accumulates between the hypodermis and four body muscle quadrants, and surrounds the pharynx, intestine and primordial gonad at L1 through adulthood. Presumptive GLRDL, GLRDR, GLRL, GLRR, GLRVL, GLRVR, coelomocytes, and anal muscles show expression in addition to body muscle cells at L1, L2, L3 L4 and adult. Distal tip cells of developing gonad in L2, L3, and L4. Spermathecal cells and distal ends of gonad show expression at L4 and adult. Vulval and uterine muscles in adult. Also expressed in two to four posterior intestinal cells. Primary Identifier  Expr518
Remark  Reporter construct derived from clones that rescue emb-9 phenotype. Transgenic Marker: rol-6(su1006). late embryo(author) = fully-elongated embryo(curator). Subcellular Localization  Preceding lima stage, intracellular. Later, extracellular around muscle quadrant-hypodermis interface, pharynx, intestine and gonad. Gonad and muscle stain intracellularly, pharynx and hypodermis do not. Four antibodies to type IV collagen gave same expression pattern.

an accordion-like tube that contains sperm and is the site of oocyte fertilization. spermatheca   WBbt:0005319
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
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
