WormMine: ExpressionPattern Expr9835

• Pattern: Broad GFP expression was observed from early embryogenesis to the mature adult. Particularly high levels of GFP were seen in the L2/L3 stages, in possibly all nuclei in the head, but certainly in many neuronal, hypodermal and muscle cells. GFP was also expressed in the larval hypodermis down the rest of the body. GFP was seen in the intestine throughout development. High levels of GFP were observed in the developing reproductive system, particularly in the spermathecae. GFP levels were generally lower in adults, apart from a few neurons in the head with very high levels, but GFP was still present in the intestine, in some neurons in the tail and possibly in body wall muscle in younger adults.

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
