WormMine: ExpressionPattern Expr14409

• Pattern: Expression of GFP under the control of the C09F5.1 promoter was observed through all developmental stages. In 3-fold embryos, GFP was localized in seam cells and hypodermal cells. In the larval stage, strong expression was detected in the sensillar region (lip), seam cells, vulval cells, intestinal cells, and tail neurons. Expression in the hypodermal cells gradually decreased as the worms progressed to L3 and L4 and almost no expression was detected in the hypodermal cells of young adults. During vulva formation, GFP was detected in a subset of vulval cells (mainly vulA) in L4. After completion of vulval development, overall GFP signal in the vulval region decreased and only persisted at the vulval junction.

female genital.	vulva		WBbt:0006748
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
