Figure 4. The migration defect in Hem mutants is not related to midline defects, identity changes or commissural defects.

Figure 4

Anterior end is up, midline is marked by vertical lines. Panels A, B: Eve and Sim double-stained embryos. Star indicates a Sim-positive cell at the midline in the same focal plane as an RP2. The RP2 in the mutant is on the midline, its sib is in its normal location. Panels C, D: Embryos are double-stained with Eve and Zfh1. The mis-migrating RP2 expresses both Eve and Zfh1. Panels E, F: Embryos are double-stained with Eve and 22C10. Panel G, H: Embryos are double-stained with Eve and BP102. Although the commissural tracts in the mutant appear normal, the RP2 has crossed the midline in the mutant.
