WormMine: ExpressionPattern Expr10710

• Pattern: Fluorescence was seen broadly throughout the embryo beginning prior to gastrulation and continuing through the L1 stage. Higher levels of expression were seen in cells that would form the head beginning at approximately the 1 1/2 fold stage of embryonic development. This pattern continued through the first larval stage with L1 animals showing GFP expression at high levels in the head and at lower levels throughout the body, including in body wall muscles, hypodermis, intestine, anal depressor muscles, and several neurons. During later larval development expression is seen in the distal tip cells (DTCs). In adults, GFP was found in the head, body wall muscles, hypodermis, DTCs and some neurons.
• Primary Identifier: Expr10710
• Subcellular Localization: SLI- 1::GFP was observed surrounding cell corpses in most transgenic animals though in a small minority of cell corpses in each animal.

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

Longitudinal bands of muscle cells surrounding animal body, with one band running in each quadrant of the body, regulated contraction and relaxation of these muscles cause locomotion.	body wall musculature	body muscle	WBbt:0005813

a single, H-shaped cell which lies just above the anus and connects the roof of the anal canal to the dorsal bodywall; its contractions act to increase the size of the anal opening by lifting the roof of the rectum and hence facilitate expulsion of intestinal contents.	anal depressor muscle	dilator muscle	WBbt:0004292
Major cell type of nervous tissue, specialized for transmission of information in the form of patterns of impulses.	neuron	neurone	WBbt:0003679
