Figure 8From: Ultrabithorax confers spatial identity in a context-specific manner in the Drosophila postembryonic ventral nervous systemDorsal view of neuroblast clones showing Ultrabithorax expression and genetic manipulation in lineage 12. Insets show either Ubx immunostaining (magenta) of sections at mid-clone (A’-H’) or adjacent to the neuroblast (A”-H”); or neurotactin immunostaining (red): single confocal slices shortly after the axon bundle enters the neurotactin scaffold (M’-P’). (A-D) Wild-type clones. (C) Only bundle 12c is present in T3. (D) Only 12id is present in A1. (E-H) dronc- clones. (G) Bundles 12c and 12id, but not 12im, are present in T3. (H) Bundles 12c and 12id, but not 12im, are present in A1. (I-L) Ubx- clones. (K) Bundles 12im, id, and c are present in T3. (M-P) UAS-Ubx clones. Cell bodies are missing and axon bundles reduced or missing in all segments. (M’-P’) Lineage 12 is still identifiable based on characteristic position in neurotactin scaffold. White or green, anti-CD8, Ubx: Ultrabithorax.Back to article page
