High voltage (1MeV) transmission electron microscopy image of a 0.5 micrometer section through a Chinese hamster ovary cell at metaphase showing a chromatid pair, with kinetochores at the centromere. ...

Echinoderm sperm nuclei are unusual in that chromatin fibers are clearly seen, allowing their diameter to be accurately determined. Here, sperm from the starfish P. miniata were treated to remove the ...

Avian erythrocytes differ from most vertebrates in retaining the nucleus at maturity. During erythrocyte development, transcription is progressively shut down and nuclei become compact and heterochrom...

Transmission electron micrograph illustrating the 'classic' appearance of the nucleus in osmium tetroxide fixed material. In this pancreatic acinar cell nucleus, the only prominent feature is the lar...

Transmission electron micrograph of a bone marrow orthochromatic erythroblast from guinea pig showing terminal differentiation in erythrocyte formation. Accompanying the cessation of most transcriptio...

Transmission electron micrograph of a cross section through the nucleolus from a Chinese hamster spermatogonium revealing a complex distribution of regions of varying granular textures.
