Fig. 6. Development of DL1 projection neuron axons. (A-J) Maximum intensity z projections of confocal stacks of representative DL1 single cell clones at successive developmental time points. Asterisks in C indicate diffuse outgrowths from the existing axon in the mushroom body calyx (blue) and lateral horn (red) areas; arrowheads in D-I indicate collaterals in these same areas. Green is mCD8-GFP, red FasII and magenta nc82.
