Transmission electron micrograph showing the extensive accumulation of darkly stained heterochromatin at the nuclear periphery typical of many differentiated cells. Heterochromatin is excluded from re...

Transmission electron micrographs of Opossum spermatogonia showing different regions within the nucleolus. One region is more lightly staining and fine textured, the other denser and more coarsely tex...

Transmission electron micrograph showing the highly compact nucleolus in the salamander hepatocyte. A finer textured central region is surrounded by a coarser region.

Transmission electron micrograph of section through the macronucleus of Nassula sp containing many darkly staining nucleoli.
