WormMine: ExpressionPattern Expr11637

• Pattern: pax-1 was expressed in 14 pharyngeal cells, which included nine marginal cells, the e2 epithelial cells and the pm8 muscle, based on morphology, position and co-staining for marginal cell filaments. Expression of pax-1::GFP in marginal cells was first detectable in two rows of pharyngeal nuclei shortly after embryonic cell division ceased, at the late-bean to early-comma stages of development. Expression gradually faded during later embryogenesis and was undetectable in larvae or adult worms.
