Expression Pattern :

Pattern  We visualized mNG::LEA-1 fluorescence in dauer larvae. We found that the protein was prominently expressed in specific tissues: the germline, body wall muscle, pharynx, and excretory cell. mNG::LEA-1 was localized to both the excretory cell body, which is adjacent to the pharynx, as well as excretory canals, which extend laterally along the length of the body. Some faint expression was seen in seam cells (lateral hypodermal cells) , as well as the intestine. Additionally, some unidentified cells in the head were fluorescent. Primary Identifier  Expr16299

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 group of hypodermal cells that lie along the apical midline of the hypodermis, at the extreme left and right sides between nose and tail seam cell lateral hypodermis WBbt:0005753
Four processes (canals) of the excretory canal cell each contain a central collecting lumen which feeds to a central lumenal canal in the cell body; the central canal forms a specialized membrane to release fluids into the excretory duct. These five canals form a continuous H-shaped channel which extends almost the full length of the body, generally in contact with the lateral hypodermis and the pseudocoelom. excretory canal canal WBbt:0005775
