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...

Time-lapse microscopy of a b-Tubulin GFP expressing mouse oocyte injected with siCo-5h, a control siRNA. Images were taken every 20 minutes. Times after the resumption of meiotic maturation and germin...

Time-lapse microscopy of b-Tubulin GFP expressing mouse oocytes injected with siTPX2-5h, a doublestranded siRNA against TPX2 (targeting protein for Xenopus kinesin-like protein, xklp2). Images were ta...

Time-lapse microscopy of mouse oocytes expressing YFP-TPX2DN, a truncated version of TPX2 (targeting protein for Xenopus kinesin-like protein, xklp2) which lacks the 118 first amino acids and injected...
