WormMine: ExpressionPattern Expr677

• Pattern: At one cell stage, there is no signal detected. Expression is first detected at two and four cell stage, pattern is variable at this stage. In most (35/48) of four cell embryos transcript is detected in posterior P1 cell or its immediate daughters. By 8 cell stage, signal detected in all blastomeres. In 3/48 expression is seen in the somatic AB cell and its immediate daughters, whereas 10/48 embryos ftt-2 messages were present in both lineages. ftt-2 transcript levels remain high in older embryos and during early elongation stage of morphogenesis, the transcript becomes localized to the region of the developing gonad and gut. Undetectable in maturing germ cells or maturing oocytes.

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
