Fig. 7. Numb and Spdo localization during MP divisions. Confocal images of
MP1 and MP4 divisions in sim-Gal4 UAS-tau-GFP (green) stage 11
Drosophila embryos stained with (A-F) anti-Numb (magenta) and
(G-L) anti-Spdo (magenta). Sagittal views with anterior left and
internal (basal) up. White arrowheads indicate: (A,B,G,H) MP4, (C,D)
Numb+ VUM4 neuron, (I,J) basal VUM4 neuron with cytoplasmic
punctate Spdo, (E,K) MP1 and (F,L) MP1 neurons. Yellow arrowheads indicate:
(C,D) Numb- VUM4 neuron, (I) apical VUM4 neuron with cytoplasmic
punctate Spdo and (J) membranous Spdo VUM4 neuron.
