Figure 2.

cg has opposite effects on the cell cycle in different regions of the eye-antennal imaginal disc. All panels are confocal projections of four optical sections centered on the apical or basal domains of late third instar eye-antennal imaginal discs. Anterior is to the left and dorsal is up. (A-D) cg promotes S and M phase entry at the SMW (white arrows). (E-H) cg limits proliferation in the presumptive head cuticle (yellow arrows).
