(A) The epithelial marker CHE-14::GFP is expressed in Y. (Right) Fluorescent photomicrograph of Y expressing CHE-14::GFP in a newly hatched L1 animal (40 of 40 early L1s expressed che-14 in Y). (Left) The corresponding Nomarski photomicrograph. CHE-14 can be detected at the apical side of the Y cell, bordering the rectal slit (white arrow), and some faint fluorescence can be seen in Y cytoplasm; note that both sides of the rectal slit are marked with CHE-14, although only one is shown in focus; arrowhead, Y nucleus.

(B) The epithelial markers DLG-1 and AJM-1 are expressed in Y. Fluorescent photomicrographs of the subapical part of the Y cell (white arrowheads) expressing both DLG-1 (green, Left) and AJM-1 (red, Center) in the same L1 animal (overlay in yellow, Right; 41 of 41 and 27 of 27 early L1s expressed dlg-1 or ajm-1 in Y respectively); thin arrow, rectal slit.

Mosaic animals are shown that express nhx-4::GFP in the distal tip cell (dtc; Y and Z).

Fig. 4. Marker expression in Y and PDA. (A) The epithelial marker CHE-14::GFP is expressed in Y.

(C) PDA is a neuron in the L3 stage. Photomicrograph of the PDA motor neuron cell body (arrowhead) and axonal process (thick arrow) in a cog-1::gfp L3 larva. PDA's axon is first directed toward the posterior of the animal on its ventral side, then it runs round to the dorsal side through a right-handed commissure past the rectum (thick arrow) and goes toward the anterior part of the worm in the dorsal cord. In cog-1::gfp or ace-3/4::gfp animals, PDA's process (thick arrow) stops just posterior to the pharynx (asterisk). The anus is indicated by a thin arrow.

Figure 6. Y Cell/PDA Neuron Transdifferentiation(A) Merged DIC and fluorescence micrographs of a wild-type larva expressing the transgene nsIs131 (exp-1pro::GFP). Insets show tail region of the animal, whiteoutline indicates Y cell/PDA neuron position. Left: early L2 stage; middle left: mid L2 stage; middle: late L2 stage; middle right: mid L3 stage; rightmost: L3 molt(3 ms/25 ms exposure DIC/GFP [1.2 W/mm2], 18 z slices, 1 mm spacing). Scale bar, 20 um.(B) Time course of fluorescence intensity at the position of the Y cell/PDA neuron for the animal in (A). Dashed line marks time points of L2 molt; dotted-dashedline, L3 molt.(C) Time course of fluorescence intensities at the position of the Y cell/PDA neuron for 25 animals. Dashed lines mark time points of L2 molt; dotted-dashed lines,L3 molt. Synchronous onset of exp-1 expression is revealed after traces are aligned to the L1 molt.
