Electron microscopy of astrocytes in arrested mitoses. a Condensed chromosomes (asterisks) are distributed over a large volume of this rounded astrocyte cell body. (a1) Intermediate filaments are not found in the cytoplasm near chromosomes. b Condensed chromosomes (asterisks) are grouped in one part of the cell body. Microtubules near centromere are indicated with arrowhead (in b1). A few microfilaments (arrows in b1 and b2) are found near chromosomes, intermediate filaments are absent. a1,b1, and b2 – enlarged boxed areas in (a and b), respectively. Scale bars: a,b = 4 μm
