WormMine: ExpressionPattern Expr1886

• Pattern: Expression of the smp-2::gfp transcriptional reporter is detected initially in twofold embryos, in one mononucleate pharyngeal muscle cell and in intestinal cells. In the L1 stage, GFP fluorescence is observed in one mononucleate pharyngeal muscle cell m6, in all intestinal cells, in the head epidermal cells, in a restricted number of body wall muscles, in inner labial sensory neurons, and tentatively in URAVL/R and URADL/R motorneurons. In L4 larvae and adults, GFP fluorescence is restricted to intestinal cells and pharyngeal muscle cell m6. During larval development of the male tail, GFP expression is observed only in the hook. In adult males, rays 8 and 9, and the tail bursa express smp-2::gfp. smp-2::gfp is not seen in hyp 9 or hyp 10.

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
