Fig. 7. Candidates of the sdf-9-expressing cells considered in the mosaic experiment [modified from figure 2 by White et al. (White et al.,1986)]. The figures show the cell bodies on the ventral side near the anterior bulb (metacorpus) of the pharynx. The top and the bottom diagrams show the left-hand and the right-hand views, respectively. Hatched cells are reported to express che-2::GFP (Fujiwara et al., 1999), and hence are excluded from the list of candidates.
