A time lapse experiment of Saccharomyces cerevisiae expressing GFP-tagged NET1. NET1 is a core subunit of the RENT complex that involves in nucleolar silencing and telophase exit; stimulates transc...

High resolution image of the DNA replication band in macronucleus of Halteria. Like hypotrichs the macronucleus of this oligotrich has a DNA replication band where DNA is synthesized. The nucleolus is...

The appearance of the macronucleus depends on the stage of the cell, whether the cell is in early, middle or late growth phase or is in stationary phase or whether the cell is dividing by mitosis or i...

Transmission electron micrographs showing the unusual configuration of nucleoli in Sertoli cells, with smaller, highly dense spherical bodies flanking a large central body. Upper micrograph from guin...

Mouse 3T3 fibroblast immunostained for the nucleolar protein nucleostemin (left, green) and UBF (right, red) marking nucleolar fibrillar centers.

Transmission electron micrograph of Leydig cell nucleus from the domestic boar contains a region (arrow) thought to represent the single X chromosome which is largely heterochromatic. The chromosome i...

Figure 374 from Chapter 15 (Cytoplasmic Inclusions) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Cell type-f from Acinus III in the salivary gland of the tick Rhipicephalus appendiculatus. These ce...

The image shows a slice through a 3D tomographic reconstruction of a mouse adenocarcinoma cell based on x-ray microscopy. Live cells were cryofixed by plunge freezing in liquid ethane and the vitrifi...

Mouse 3T3 fibroblast stained for the nucleolar protein nucleostemin (left, green) and signal recognition particle RNA SRP-RNA (right, red).

A micrograph showing the polyploidal macronucleus of Tetrahymena containing many copies of the genome. Chromatin material is found as condensed electron opaque spots as well as in an uncondensed form...
