Aurora-related proteins are correctly localized in EnM MKs. (A) Murine MKs were fixed and stained for CENP-E (green) and α-tubulin (red). DNA is shown in blue. Note that CENP-E is localized to kinetochores and bi-orientation of chromosomes is visible at top of the spherical arrangement of spindle poles. (B) Murine MKs were fixed and stained for aurora-A kinase (green) and α-tubulin (red). DNA is shown in blue. Note localization of aurora-A kinase to spindle poles. Image is shown as a projection to display multiple spindle poles in the same view.
