WormMine: ExpressionPattern Expr12161

• Pattern: Transgenic worms containing the smf-3 pro::gfp construct demonstrated strong GFP expression at all stages of development, beginning as early as the comma stage embryo and continuing through larval and adult stages. Expression was spatially confined to intestinal cells, excretory cells, vulval epithelial cells, and neuronal cells. Fluorescence was largely observed at the apical ends of the adult and larval intestines; in neuronal cells, particularly in the head neurons and hypodermis; in H-shaped excretory cells; and in vulval epithelial cells. Worms expressing the smf-3 pro::gfp construct exhibited distinct intestinal expression, which encompassed most of the intestine.

cell of epithelium, the layer of cells that cover the external surface of an organism as well as forming an inner lining between the tissues and organs of that organism and the external environment. In C. elegans epithelial cells include epithelium of the alimentary tract, intestinal cells, hypodermis, interfacial cells and somatic gonad cells.	epithelial cell	epithelium	WBbt:0003672
any of 20 large epithelial cells which form a tube and are mostly situated as bilaterally symmetric pairs around the tubular lumen. Each of these cell pairs forms an intestinal ring ( II-IX int rings). The most anterior intestinal ring (int ring I), however, is made of four cells. Intestinal cells contain large nuclei with large nucleoli and numerous autofluorescent granules in their cytoplasm.	intestinal cell		WBbt:0005792
