gene expression limited to excretory system cells?

Model Organism: Worms Scientific Discussion

I’m using WormMine to identify genes expressed in one or more cells of the ES to help me dissect my own gene::gfp expression patterns. However, can anyone help
by suggesting genes with such specific and limited expression?

I know that nhr-31 is strongly expressed in the ES. Marc Van Gilst had a nice paper showing this (http://www.ncbi.nlm.nih.gov/pubmed/19668342). In it, they also discuss a number of vha genes (vha-1, -2, -4, and -8) that are ES-specific.
