Frog (Xenopus laevis) egg arrested in metaphase of mitosis. Note the tiny metaphase spindle on the top left of the egg. Eggs were fixed in 90% MeOH; 10% (H20 500mM EGTA) and stained for DNA with YoP...

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...
