Fig. 4. shar-pei mutant cells upregulate Cyclin E levels. (A-C)
shrp1 mutant clones in the eye disc marked by the absence
of GFP expression (red) stained for Cyclin E (green). (C) merged channels.
Cyclin E is upregulated in cells of shrp mutant clones (arrows), in
particular posterior to the SMW (arrowhead).
