Fig. 4. Embryonic origin of laminar pattern. (A,A') Expression
of ppk-eGFP in larval class IV sensory cell bodies, dendrites and
axons, and expression of photoconverted Kaede protein under the control of
Gal4109(2)80 to label all da neurons. Labeled oenocytes
are encircled. (B) Dorsal view of stage 17 embryonic scaffold of class
IV axons (arrowhead) flanked on both sides by other da axons expressing red
Kaede protein (arrows). (C) The laminar pattern of class IV neurons
(arrowhead) and other da neuron (arrow) in early larval stages. Scale bars: 50
µm in A,A'; 10 µm in B,C.
