Fig. 4. PN dendrites occupy discrete regions of the lobe at 18 hours APF. (A) Two
DL1 single cell clones in the same brain; both occupy a similar region of the
dorsolateral corner of the developing AL. The green (CD8-GFP) and blue
(TOTO-3-stained DNA) channels are from a single optical section about 12 µm
into the lobe, whereas the red channel (FasII) is a maximum-intensity
z projection of 46 1-µm sections. (B) Two anterodorsal neuroblast
clones imaged at the same depth in the developing AL. Arrowheads indicate an
example of a bilaterally symmetric focal concentration of dendrites, probably
VA1d/VA1lm; an arrow indicates probable VA3 dendrites. (C-E) Single cell
clones generated 72 hours after larval hatching can be divided into three
morphological classes. (C1-C3) Class I have dendrites to
the lateral edge of the lobe. (D1-D3) Class II have
dendrites in the dorsomedial corner of the lobe. (E1-E2)
Examples of single cell clones with two main dendritic branches. (F) A pair of
single cell clones in the same hemisphere, with two distinct zones of
innervation.
