Description

In the absence of boi (boi[e] mutant), Hedgehog (Hh, red) is redistributed from apical cells to the extracellular space of the local follicle stem cell niche (CIL# 13744, 13745). Expression of Boi in apical cells relocalizes Hh to apical cells (CIL#13746). Apical cell expression of Ihog, which also binds Hh directly, rescues Hh localization in the boi[e] mutant (this image; boi[e]; ihog[EP]/+; babGal4/+). Germ cells are identified with anti-Vasa (blue). Image is Fig 3E in J Cell Biol. 2010. 191: 943-952. Images in Fig 3 include CIL# 13744, 13745, 13746, 13747, 13748.

Technical Details

Fly ovaries were dissected and fixed as described previously (O'Reilly et al., 2008). Primary antibodies were 1:2,000 rabbit anti-Vasa; 1:100 goat anti-Hh (Santa Cruz Biotechnology, Inc.). Secondary antibodies used were FITC, Cy3, and/or Cy5 conjugated to species-specific secondary antibodies (Jackson ImmunoResearch Laboratories, Inc.). Samples were mounted in Vectashield mounting medium. Images were collected at room temperature (22C) using 40× (1.25 NA) or 63× (1.4 NA) oil immersion lenses (Leica) on an upright microscope (DM 5000; Leica) coupled to a confocal laser scanner (TCS SP5; Leica). LAS AF SP5 software (Leica) was used for data acquisition. Images representing individual channels of single confocal slices from the center of each germarium were exported as TIFF files, and images were converted to figures using Photoshop software (Adobe).
