WormMine: ExpressionPattern Expr8282

• Pattern: In addition to the previously reported expression in pharyngeal muscle and neuronal processes in the nerve ring, authors observed, beginning at the L1 larval stage, expression of gfp in neurons in the head, neurons in the tail (including PVT and PVQ), ventral cord motorneurons, and in adults in vulval muscle and uterine cells. Authors also observed faint expression of gfp in the posterior intestine. Authors did not observe expression in the HSNs or VC neurons.
• Primary Identifier: Expr8282
• Remark: Animals expressing a Pser-1::gfp transgene containing a 3.4 kB upstream promoter region failed to express gfp in the vulval muscles but did express gfp in many of the other cells seen with the 8 kB promoter reporter construct. Picture: Figure 2B, 2C, 2D.

neuron with cell body associated with the ventral nerve cord.	ventral cord neuron	ventral cord motoneuron	WBbt:0005300
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
