Transmission electron micrograph of a thin section of the nucleus of a normal HeLa cell showing a tangential view of the nuclear envelope with nuclear pores. From a study of the role of the nuclear porin ALADIN. Other images in this group show additional details of nuclear pore structure.
Normal HeLa cells expressing were fixed with glutaraldehyde, embedded in epoxy resin, thin sectioned, and imaged using a Philips CM10 TEM. See: J Cronshaw and M Matunis 2003 The nuclear pore complex ALADIN is mislocalized in triple A syndrome Proc Natl Acad Sci USA 100 5823-5827
