figure 2. Cells that express cdh-3 reporter constructs during embryonic morphogenesis and postembryonic development. Two different reporter constructs were used (see Materials and Methods): (A-C) animals carrying extrachromosomal copies of the pJP#19 reporter construct; (D-H) animals carrying extrachromosomal copies of the reporter construct pJP#38. In each case the bar indicates 10 µm.(A) Right lateral view of a 1.5-fold embryo. Dorsal is to the left and anterior is to the top. The lacZ-expressing nuclei of the right seam cells are labelled. The small arrow indicates the position of the lacZ-expressing hyp10 cell. The arrowheads indicate the positions of four lacZ-expressing nuclei whose positions are consistent with those of arcade cells. (B) A later stage embryo (2-fold) showing continued lacZ expression in the seam cells. The arrow indicates the position of the rectum. (C) A ventral view of a 1.5-fold embryo, showing the large lacZ-expressing excretory cell nucleus (arrow). (D) Dorsal view of a newly hatched L1 larva. The GFP-expressing seam cells on the left side are labelled; the numbering corresponds to those of their right homologues. Note that V5L and R have divided, but the other seam cells have not, indicating that this animal was photographed approximately 5 hours after hatching. The F and U cells (just out of the focal plane) are indicated with an arrowhead and the hyp11 and hyp10 cells by arrows. (E) A right lateral view of an adult hermaphrodite showing GFP expression in the arcade cells. In earlier stages it is more difficult to resolve these cells. The anterior (a) and posterior (p) arcade cell bodies are indicated. The other arcade cell bodies (three from the posterior arcade and one from the anterior arcade) are not visible in this focal plane. (F) Lateral view of the rectum of an L2 larva. The GFP-expressing F and U cells are indicated by large arrows. The small arrow shows the position of the anus. (G) Residual GFP expression in the excretory cell of a newly hatched L1 larva (right lateral view, anterior is to the right). The arrow indicates the cell body. Triangles indicate the anteriorly and posteriorly extended lateral processes; only the right lateral processes are visible in this focal plane. (H) GFP expression in the hyp10 and hyp11 cells of the tail of an L1 larva.

Figure 3. cdh-3::GFP expression in the egg-laying system of animals carrying extrachromosomal copies of the pJP#38 reporter construct. In each case the bar indicates 10 µm. (A) An L3 larva. The developing gonad (G) and ventral epidermis (E) are indicated. The arrow indicates the GFP-expressing anchor cell. The triangles indicate those nuclei of the developing vulva that are visible in this focal plane. (B,C) GFP expression beginning in the invaginating vulval epidermal cells of an L3 larva. Note the anchor cell (AC) between the two nearest vulval cells (arrowheads). VC indicates the GFP-expressing VC5 neuron (see E). The developing gonad (Gon) and ventral epidermis (Epi) are indicated. (D) Left lateral view showing GFP expression in the utse cell of an L4 stage larva. Arrowheads indicate the positions of attachments to the seam cells (se). The GFP-expressing vulval epidermis (out of the focal plane) is indicated by the triangle. The left HSN is visible (arrow), though its anterior process is not. (E) GFP expression in the VC neurons of an L3 larva. Anterior is to the right. GFP expression in the developing vulva is indicated by an arrow.

Figure 2. R06F6.1::gfp is expressed in all somatic cells throughout development. (A) Confocal Z-series projection of an embryo approximately 300 minutes after the first cell division. (B) An epifluorescent image of the expression of R06F6.1::GFP in an L2 larva. The actively dividing nuclei of the lateral hypodermal cells are indicated by arrowheads, and an intestinal nucleus (which undergoes endoreduplication during postembryonic development) is indicated by an arrow. These cells show stronger GFP expression than non-dividing cells. (C) Epifluorescence image showing that nuclei of recently divided cells strongly express R06F6.1::GFP. The cells that form the postdeirid (boxed) and two lateral hypodermal cells (arrows) show stronger expression than neighbouring cells. Scale bars represent 10 um.
