WormMine: ExpressionPattern Expr9051

• Pattern: In wild-type embryos, ten-1a::gfp is first expressed in a cluster of cells in the anterior half at approximately 150 minutes after fertilization. These cells are precursors to the hypodermal cells, which are evident at 300 minutes post-fertilization, when the cells intercalate and begin the process of ventral closure, and to pharyngeal and intestinal cells, which are evident beginning at the bean stage. In later stages, strong expression of ten-1a::gfp persists in pharyngeal and intestinal cells, and appears in several head neurons. Examination of L1 larvae and adults allowed us to identify 8 pharyngeal cells that express ten-1a::gfp: the three marginal cells mc1, the three marginal cells mc3, and the neurons M2L and M2R. Adults also express ten-1a::gfp in vulva muscles, the gonad distal tip cells, the intestine, several tail neurons including DVB and some other cells.

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
