stn-1 is expressed in muscles and neurons. Expression of
stn-1 was assayed by reporter gene analysis. Fluorescence microscopy images of wild-type animals carrying a
stn-1:gfp transgene. A, Expression in a twofold embryo seen with a fluorescence microscope (630). GFP fluorescence is detected in the head neurons and muscles. B-E, Expression in a adult hermaphrodite seen with a confocal microscope. B, Projections of series of ventral views (400). Staining is visible in the nerve cord (long arrow) and muscles (short arrow). C, Lateral view of the vulva showing intense staining in the vulva muscles (630). D, Staining of body wall muscle cells (630). E, Projections of series of ventral views (630). Staining is visible in the nerve cord (long arrow), body-wall muscles (short arrow), and vulva muscles (vertical arrow).
