Fig. 5. Hfp negatively regulates G2-M progression. (A-F) Wild type, (G-L)
GMR-GAL4/+, UAS-dmyc/+ and (M-R) GMR-GAL4/+,
UAS-dmyc/hfpEP. Cells posterior of the morphogenetic furrow
stained with the nuclear stain PI in red (A,G,M) and for cell size with
spectrin in green (B,H,N). Scanning electron micrographs showing ommatidia at
high power (C,I,O) and the overall size of the adult eye (D,J,P). Analysis of
cell cycle progression posterior of the MF in third instar larval eye discs
using BrdU (E,K,Q) and anti-phosphohistone H3 (F,L,R). The MF is indicated
with a yellow bar.
