WormMine: ExpressionPattern Expr2292

• Pattern: GFP was observed in many of the tissues stained by the SQV-4 Abs, including the vulva, uterus, intestine, seam, and hypodermis. GFP was absent in oocytes, probably because expression from transgene arrays is silenced in the germline. GFP was observed in vulval cells containing 10 nuclei in the early L4 stage and in vulval cells containing 14 nuclei in later L4, consistent with the pattern of Ab staining.

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

The organ in which the eggs are developed and protected until laid.	uterus		WBbt:0006760
