Scanning electron microscopy of nuclear structure.

???displayArticle.abstract???
Accessing internal structure and retaining relative three dimensional (3D) organization within the nucleus has always proved difficult in the electron microscope. This is due to the overall size and largely fibrous nature of the contents, making large scale 3D reconstructions difficult from thin sections using transmission electron microscopy. This chapter brings together a number of methods developed for visualization of nuclear structure by scanning electron microscopy (SEM). These methods utilize the easily accessed high resolution available in field emission instruments. Surface imaging has proved particularly useful to date in studies of the nuclear envelope and pore complexes, and has also shown promise for internal nuclear organization, including the dynamic and radical reorganization of structure during cell division. Consequently, surface imaging in the SEM has the potential to make a significant contribution to our understanding of nuclear structure.
