Spartium flower primordium (bud), captured using epi-illumination. Honorable Mention, 2010 Olympus BioScapes Digital Imaging Competition®.

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...

Fluorescent micrograph of a Drosophila melanogaster reproductive system highlighting the muscular and neural structure fruitfly ovaries and uterus. The background staining of the eggs in red is a spe...

Detail of a pod of flowering legume Scorpius muricatus. Stereomicroscopy, darkfield illumination. Honorable Mention, 2011 Olympus BioScapes Digital Imaging Competition®.

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...

Reproductive tissue of olive (Olea europaea) pistil during the progamic phase.

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 ...

Following unsuccessful pollination, cells from the Olive (Olea europaea L.) ovary start apoptosis.

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...

An oocyte in a mature follicle. During the menstral cycle in females the ovary produces oocytes, which develop in follicles. As the follicle matures it increases in size, different cell types are recr...
