WormMine: ExpressionPattern Expr4761

• Pattern: A transcriptional reporter consisting of 1.7 kb of 5' regulatory sequences upstream of the egl-43L start codon showed GFP expression first in the ventral uterine (VU) cells of mid L2 larvae (Pn.p stage) and then in the AC beginning in mid L3 larvae, after the first round of vulval cell divisions had occurred. AC expression increased during AC invasion in late L3 larvae, but remained constant in the VU descendants. gfp expression was also observed in the gut and a set of neurons in the head region. However, no expression could be detected in the vulval cells during vulval cell fate specification and AC invasion.
• Primary Identifier: Expr4761

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
