arm is required for the formation of supernumerary neuroblasts induced by overexpression of klu. (A-C′) The removal of arm function significantly reduces the formation of supernumerary neuroblasts induced by overexpression of klu. Larvae carrying GFP-positive type II neuroblast mosaic clones (outlined by the yellow dotted line) were aged for 72 hours after clone induction, and brains were stained for the markers indicated. (D) The frequency of clones containing one or more Dpn⁺ type II neuroblasts in larvae of the genotype indicated. (E-F′) Co-expression of Apc2 suppresses supernumerary type II neuroblasts induced by overexpression of klu. (G) The total number of neuroblasts per clone in larvae of the genotype indicated. Error bars indicate s.d. ^*P<0.05 versus control (Student’s t-test). See Fig. 2 for description of labels. Scale bars: 10 μm.
