Pins-7::gfp is expressed in multiple tissues, including several head neurons and the intestine, consistent with previous findings (Murphy et al., 2007). The ins-7-expressing head neurons include ADF, ASI, ASK, and URX among others.
The C+C enhancer (pOK17.21) activates frequent expression in all pharyngeal muscles. the C+C enhancer also activates expression in non-muscle cells in the pharynx. Expression induced by the C+C enhancer was observed in all pharyngeal cell types including gland cells, neurons and marginal cells as well as muscles. These results define C as an organ-specific subelement.
