Figure 6

Symmetrically dividing optic lobe precursors are maintained in culture. (A, B) Proliferating cells shown by BrdU incorporation (green) and DAPI staining (blue), after 15 h in culture. Shown are doublets containing cells of equal size (A) and unequal cell size (B). (C) Larval brain lobe with, c885- Gal4 driven UAS-mCD8::GFP, UAS-H2B::RFP (red). (D, E) Shown are a doublet (D) and a triplet (E) of cells with incorporated BrdU (green), that are also positive for H2B::RFP (red) Dapi (blue).
