WormMine: ExpressionPattern Expr950

• Pattern: Early in development, 1497pro-mab-3::gfp was expressed in head neurons of late embryos and L1 larvae of both sexes. Later in larval development, starting in L3, it was expressed in the lateral hypodermis (seam) in both sexes, and male-specifically in the nervous system, both in the head and tail, including the sensory ray neuroblasts R1-R9 in the tail. Initially there is some expression in the intestine of both sexes, but expression becomes male-specific by the adult stage, when vitellogenin transcription begins in hermaphrodites.

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
