Transmission electron micrograph of stacked annulate lamellae from the oocyte of the sea urchin Arbacia. Annulate lamellae consist of sheets of membrane containing closely packed structures resemblin...

Fluorescent image of a mouse oocyte labeled with an antibody to tubulin, which is shown localized in the cortex of the oocyte. The sample was fixed in paraformaldehyde for subsequent immunolabeling wi...

Transmission electron micrograph showing the characteristic features of the synaptonemal complex in a thin section of a Drosophila oocyte.

Dividing egg of the jellyfish (Spirocodon saltatrix showing birefringent spindles. The arrow indicates the direction of the compensator slow axis. AS the cell is rotated 90 degrees with respect to the...

How the cell cytoplasm is spatially organized is of fundamental interest. In ordinary animal cells the cytoplasm is organized by a radial array of microtubules, called an aster. Aster microtubules are...
