Fig. 5. Egg chambers from JIL-1 mutant flies labeled with lamin Dm₀ antibody. (A) Wild-type (WT) egg chamber labeled with lamin pAb R836. The location of follicle cells (f), nurse cells (n) and the oocyte (o) is indicated by arrows. (B) Egg chamber from a JIL-1^z2/JIL-1^h9 (z2/h9) mutant fly labeled with lamin pAb R836. The arrows indicate dispersed and mislocalized lamin Dm₀ throughout the egg chamber. (C,D) Egg chambers from a JIL-1^z2/JIL-1^h9 (z2/h9) mutant fly labeled with lamin pAb R836. The arrows point to protrusions of the nuclear lamina of nurse cells near the oocyte. (E,F) Egg chambers from a JIL-1^z2/JIL-1^h9 (z2/h9) mutant fly double-labeled with lamin pAb R836 (green) and phalloidin (red). The protrusions from the nuclear lamina of the nurse cells extend through the ring canals. Bars, 25 µm in A-D and 10 µm in E-F.
