Fluorescent micrograph of stage V-VI Xenopus laevis oocytes surrounded by thousands of follicle cells, as visualized by Hoechst staining.

A photomicrograph of a stained semi-thin section of mouse ovary, showing a maturing Graafian follicle. The ovary contains many follicles that contain immature oocytes (egg cells). The follicle is impo...

A colorized scanning electron micrograph of a human egg, which is the huge cell colored yellow at the bottom of this image. The follicle cells that surround it (top) send out long projections that pen...

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...

This batik was produced from a hematoxylin and eosin stained section from a neonatal mouse ovary. The image shows various structures within the ovary, including five oocytes in developing follicles. B...

In situ hybridizations showing the localization of bicoid (top), oskar (middle) and gurken (bottom) mRNAs in the stage 10 Drosophila egg chambers. These localizations define the anterior- posterior a...

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...
