FIG.2E Changes in ER cluster morphology require gamete fusion.

FIG. 4G 4G' Changes in cortical ER clusters at the site of sperm binding and incorporation.

Light micrograph of human ovum (egg) and sperm. The ovum is much larger than the sperm and is surrounded by protective cumulus cells around the outside surface (yellow). The membrane surrounding the o...

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...

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...

This fluorescent micrograph shows the developing egg chambers within the Drosophila melanogaster (fruit fly) ovary. The egg chambers house the maturing eggs - these are the cells at the tips of the eg...

Brightfield image of stink bug eggs. Stink bugs are agricultural pests that exist throughout the world and emit a characteristic foul-smelling odor when disturbed. Eggs are laid in clusters (averagi...

The time lapse movie spans fertilization, ooplasmic segregation, and early divisions in the egg of the tunicate Phalusia mammilata. Contrast is provided by both polarizing microscopy and differential...

Meiotic newt oocyte nuclei were allowed to disperse in 30 mM KCl/NaCl, centrifuged through 2% formaldehyde onto an EM grid, stained with uranyl acetate, and critical point dried. Grids were examined ...
