Fig. 4. Loss of hop activity does not affect the acquisition of terminal filament cell and cap cell fates. Drosophila germaria harbouring hop^c111 somatic clones stained with TOPRO-3 (blue), anti-GFP (green) and anti-Engrailed (A-A'') or anti-Lamin C (B-B'') in red. The expression of Engrailed or Lamin C proteins is not altered in mutant cells when compared with wild-type neighbours. Yellow open arrowheads, wild-type TFCs; yellow arrowheads, wild-type CpCs; white open arrowheads, mutant TFCs; white arrowheads, mutant CpCs. The genotype of these germaria is hop^c111 FRT-101/GFP FRT-101; bab1-Gal4 UASt-flp/+.
