boi controls follicle stem cell proliferation. Germaria from wild-type in which germ cells (blue, anti-Vasa) and differentiating follicle cells (red, anti-Fas3) are labeled. Stalks between the germari...

Boi (red) localizes predominantly to apical cells in Drosophila wild-type germaria but not in germaria with UAS-boi[RNAi] expression (CIL#13742). Germ cells are identified using anti-Vasa (blue). Imag...

Expression of UAS-tauGFP (the tau-GFP fusion protein binds microtubules; green) under control of babGal4 in wild-type Drosophila germaria. babGal4 is expressed at high levels in apical cells. Nuclei a...

Expression of UAS-tauGFP (the tau-GFP fusion protein binds microtubules; green) under control of 109-30-Gal4 in wild-type Drosophila germaria. 109-30-Gal4 drives UAS-tauGFP expression in follicle ste...

boi controls follicle stem cell proliferation. Germaria from boi[e] mutant in which germ cells (blue, anti-Vasa) and differentiating follicle cells (red, anti-Fas3) are labeled. Stalks between the ger...

Boi (green) localizes predominantly to apical cells in Drosophila wild-type germaria but not in boi[e] mutant germaria (CIL#13740). Germ cells are identified using anti-Vasa (blue). Image is Fig 2B in...

Boi (green) no longer localizes predominantly to apical cells in Drosophila boi[e] mutant germaria (compare with CIL# 13739). Germ cells are identified using anti-Vasa (blue). Image is Fig 2C in J Cel...

Boi (red) localizes predominantly to apical cells in Drosophila wild-type germaria (CIL# 13741) but not in germaria with UAS-boi[RNAi] expression in apical cells (cells expressing UAS-boi[RNAi] also e...

Expression of UAS-tauGFP (the tau-GFP fusion protein binds microtubules; green) under control of 109-30-Gal4 in wild-type Drosophila germaria. 109-30-Gal4 drives UAS-tauGFP expression in follicle ste...

The Hedgehog (Hh) pathway is activated in follicle stem cells of animals lacking boi (boi[e]; this image), relative to wild-type Drosophila (CIL# 13756), based on activated cubitus interruptus (ci) st...
