WormMine: ExpressionPattern Expr4684

• Pattern: GFP expression was detected at most developmental stages, with the spatial expression depending on the developmental stage of the animal. Neuronal expression of hlh-29 was detected in larvae and adults in both amphid and phasmid sockets, in the ALA and PVT neurons, in the chemosensory and mechanosensory neurons, ASI, ASK, PHA, and PQR, and in neurons of the anterior pharyngeal bulb. Weaker expression was also detected in the ASG chemosensory neurons in some transgenic lines. L1 animals show strong expression of hlh-29 in intestinal cells, and weaker expression in the rectal glands and the pharyngeal muscle cell PM1. By L3 stage, intestinal expression of the hlh-29::GFP is limited to the posterior intestinal cells, and PM1 expression is no longer detected. Expression is also detected in the ventral posterior coelomocytes in the later L3-stage larvae, and in the spermatheca and vulval muscles of L4 and adult animals.

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
