Boi (green) and Hedgehog (Hh, red) are expressed in apical cells of the Drosophila wild-type germarium (CIL# 13744). In the absence of boi (boi[e] mutant), Hh is redistributed from apical cells to the...

Patched (Ptc, green) is expressed in most cells of the Drosophila wild-type germarium including follicle stem cells. Hedgehog (Hh, red) accumulates on the surface of the apical cells. Germ cells are i...

Boi (green) and Hedgehog (Hh, red) are expressed in apical cells of the Drosophila wild-type germarium. In the absence of boi (boi[e] mutant), Hh is redistributed from apical cells to the extracellula...

Smoothened (Smo; green), a downstream effector of Hedgehog (Hh), is expressed in most cells of the wild-type Drosophila germarium including follicle stem cells, but is excluded from Boi- and Hh-expres...

The Hedgehog (Hh) pathway is activated in follicle stem cells of animals lacking boi (CIL# 13757), relative to wild-type Drosophila (this image), based on activated cubitus interruptus (ci) staining (...

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) and Hedgehog (Hh, red) are expressed in apical cells of the Drosophila wild-type germarium (CIL# 13744). In the absence of boi (boi[e] mutant), Hh is redistributed from apical cells to the...

Hedgehog (Hh, red) is transcribed in apical cells of the Drosophila wild-type germarium (CIL# 13755, 13744). In the absence of boi (boi[e] mutant), Hh protein is redistributed from apical cells to the...

Hedgehog (Hh, red) is transcribed in apical cells of the Drosophila wild-type germarium (CIL# 13755 and this image). In the absence of boi (boi[e] mutant), Hh protein is redistributed from apical cell...
