WormMine: ExpressionPattern Expr3679

• Pattern: Expression was most dramatic in the anterior and posterior two to four intestinal cells, head and tail body-wall muscles, and in the hypodermal syncytium. Intestinal expression is detected in late embryogenesis and gradually decreases in anterior intestinal cells until it is not detectable in adults, but it persists in the posterior intestinal cells well into adulthood. Hypodermal, and head and tail body-wall muscle, expression is also detected late in embryogenesis and persists into adulthood. In the hermaphrodite gonad, expression is seen in the spermatheca, starting in young adult hermaphrodites and remaining strong in older adults. Rare expression is also detected in three to five unidentified neurons in the nerve ring.

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
