WormMine: ExpressionPattern Expr8827

• Pattern: GFP signals were detected during all stages of C. elegans development (larvae L1 to L4 and adult hermaphrodites). Strong far-7::GFP expression was observed in parts of the hypodermis, in particular the syncytia covering the lips and parts of the head region. The second major localization of far-7::GFP expression was in the H-shaped excretory cell. Expression in the head hypodermis and the excretory cell remains upon fasting, but additional strong expression of far-7::GFP is observed in the hypodermal syncytium (hyp7) covering the body of the animal.
• Primary Identifier: Expr8827
• Remark: Picture: Figure 4.
• Subcellular Localization: far-7::GFP expression is observed in the cytoplasm of the excretory cell and not in the lumen of the excretory duct.

H-shaped cell associated with the excretory system, largest cell in C. elegans.	excretory cell	excretory canal cell	WBbt:0005812
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
