AtypFIG 2: XXX cells are found near the anterior bulb of the pharynx in the adult animal.
A. XXXL is located anterior to the nerve ring and close to the cells of the lateral and ventral labial sensilla.. XXXR is found in a similar position on the right side (not shown) (based on White at al., 1986).
B-D. Epifluorescent images of adult animals from a strain expressing the sdf-9::GFP reporter in XXX cells. B,C Lateral view. D. Ventral view. XXX cells have variable shapes and positions. In some animals the anterior process, which travels with the ventral labial process bundles, can be long (not shown). (Strain source: K. Ohkura, N. Suzuki, T. Ishihara and I. Katsura.)
E-H. Images of adult animals from a strain expressing the daf-9::GFP reporter in the nuclei of XXX cells. E. Ventral view of the overlay of the epifluorescent and DIC images of an animal. XXX cells (arrowheads) are positioned symmetrically on ventral lateral sides of the isthmus, near the anterior bulb. F. DIC image of an animal. (Arrowhead) XXXL nucleus. G. Same animal as in F. Shown together with the DIC image is the epifluorescent image with GFP expressed in the XXXL nucleus. H. Same animal as in F and G, epifluorescent image only. F-H. Ventral oblique view. XXX cell has a small compact nucleus. (Strain source: D. Riddle.)
