Fig. 8. Expression of IR-EcR (core) in Tv cells during remodeling. (A) SCP-labeled, fixed Tv cell axons from cells expressing IR-EcR (core). (B) Arbor footprint, from pupariation to adult for control cells and cells expressing IR-EcR (core). (C) Live imaging montage of Tv axons (T1, T2 and T3; T1 at top) of UAS-IR-EcR (core)-expressing cells, from 32 to 39 hours apf, 60 minutes apart. Filopodia are present and stabilize into adult-type branches (arrowhead), but the arbor retains a larval-like dense core (arrow). (D) Quantification of filopodia on control cells and cells expressing IR-EcR (core).
