Fig. 6. Branched ovariole and shortened ovariolar sheath in Cct1 and
Drosophila Wnt4 mutant ovaries. Ovaries were stained with Orb
antibody (red) to label the oocyte, phalloidin (green) to visualize the actin
cytoskeleton and Hoechst (blue) to label the DNA. (A)
Cct199 mutant ovary with branched ovarioles. (B) Branched
ovarioles in Drosophila Wnt4C1 mutant ovary. (C) Wild-type
ovariole showing egg chambers stretched out within ovariolar sheath. (D)
Cct199 mutant ovariole with egg chambers curled up within
the sheath.
