Higher order chromatin architecture in the cell nucleus: on the way from structure to function. Export

In this review we describe controversial views on higher order chromatin organization from the level of higher order chromatin domains built up from folded chromatin fibers to the level of chromosome territories and the interchromatin compartment (IC), which harbors non-chromatin nuclear domains, such as interchromatin granule clusters (IGCs visualized in the electron microscope) or splicing factor-containing speckles (visualized by fluorescence microscopy).
