First Prize: Sheng-Wen Chiu, Department of Biochemistry, University of Oxford
In filamentous cells of the bacterium Rhodobacter sphaeroides, the tubulin homolog FtsZ (tagged with CFP) forms dot-like and spiral structures in two distinct populations. The FtsZ cytoskeleton affects the localization of the membrane chemosensory protein clusters (YFP). Cell bodies are shown in magenta.
Second Prize: Zuni Irma Bassi, Department of Pathology, University of Cambridge
The image shows a midbody purified from HeLa cells synchronized in cytokinesis that has been fixed and immuno-stained to detect tubulin (shown in red) and Citron kinase (shown in green).
Third Prize: Dr Daniel Booth, Wellcome Trust Centre for Cell Biology, University of Edinburgh
A scanning electron micrograph (SEM) of DT-40 cells adhered to glass and fixed with aldehydes. The cells were pseudo coloured to make them resemble scoops of ice-cream.
