• Primary Identifier: Expr3225
• Remark: Reporter gene fusion type not specified.
• Pattern: LEV-8 is first detected in L1 animals in a single pair of neurons in the head, approximately midway along the isthmus. It is also expressed in the PVT interneuron situated in the lumbar ganglion, at the rear of the animal. By L4, LEV-8 is expressed in all six DD motor neurons in the ventral nerve cord. As well as expression in several neuronal cell types, LEV-8 is expressed in body wall and in uterine muscles UV1 and UV2. Expression in the body wall was strongest anteriorly, which accords with the higher level of resistance exhibited by the head muscles of lev-8(x15) mutant worms. In the adult worm, LEV-8 is expressed in many neurons in the anterior nervous system. One of the more prominent of these is a single cell in the dorsal ganglion, ALA. LEV-8 is expressed in the IL and OL socket cells but not the neurons themselves.

• Primary Identifier: Expr2570
• Pattern: Examination of male and hermaphrodite worms possessing the T03F1.5 pro::GFP construct demonstrated consistent GFP expression in two different anatomical regions. The first region identified was at the posterior end of the intestine of both hermaphrodite and male worms at all larval stages, and was consistent with the location of the sphincter muscle. The second region was at the anterior end of both hermaphrodite and male worms. Two cells anterior to the first pharyngeal bulb were linked to consistent GFP expression from the L1 to the adult stages. The two cell bodies located in the hypodermis on the dorsal and ventral side of the 'head' appeared to contain cellular processes which extended to the anterior end of the worm, in a fashion similar to dendrites. These processes bifurcated toward the anterior end, with the dorsal and ventral branches predicted to terminate in sensillae near the surface. Comparison of the observed expression patterns and the anatomical 'map' of C. elegans hermaphrodites indicated that no neurons are localised to this region, suggesting that the cells were not of this category. Instead, the GFP expression was consistent with two neuron-associated cells, namely the inner labial socket cell dorsal left (IlsoDL) and inner labial socket cell ventral left (IlsoVL). Transgenic worms which contained the pc::GFP (promoter and coding sequence) constructs showed similar expression profiles to those containing the promoter alone, but the GFP expression was significantly reduced.

• Primary Identifier: Expr9160
• Remark: Picture: Fig. 3.
• Pattern: Expression of itx-1prom::gfp was observed in the intestinal tract of embryos from 1.5-fold stage throughout post-embryonic larval development and adulthood. Furthermore, GFP could be detected in socket cells ensheathing the inner and outer labial neurons. Expression could also be observed in the spermatheca and vulva muscle cells. No other cell type displays consistent reporter gene expression.

• Primary Identifier: Expr2425
• Remark: No detailed description on expression patterns in other life stages. Reporter gene fusion type not specified.
• Pattern: In adult hermaphrodites, F22A3.1 reporter expression was observed in the inner and outer labial socket cells of the head. F22A3.1 is expressed strongly in the seam cells within the hypodermal ridges, which extend bilaterally along the length of the exterior body wall. During the first larval stage, F22A3.1 also demonstrated expression in P-cells, the ventral hypodermal precursors, some of which form the vulva. In general, F22A3.1 seems to be quite specific to hypodermal tissues and is probably expressed in all hypodermal cells including glial-like cells.
