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 ...

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...
