When trichocysts are triggered to discharge their contents the body of the trichocyst expands 8 or 9 times into a long needle like filament, however, the trichocyst tip does not change shape. The tric...

Toxicysts in the cytoplasm of cross sectioned non-dividing Didinium. Toxicysts (extrusomes) are multilayered cylinders that are discharged from the cytopharynx region during capture of prey such as Pa...

Fully formed trichocysts are moved from the cytosol to the cell surface along microtubules. In this image a bundle of microtubules arising from the proximal end of the basal body lies against the tric...

Microtubule detachment from the spindle pole body in kar9delta nip100deltaCAP-gly double mutant cells arrested in S phase. Movie plays at 20x real time and is movie S8 in Proc Natl Acad Sci. 2009. 106...

Nuclear envelope and spindle dynamics when the nucleus moves into the neck of kar9delta Nip100deltaCAP-Gly double mutant cells arrested in S phase. In these cells, the spindle failed to enter the bud ...

Timelapse movie of GFP-labeled microtubules in kar9delta cells (arrested in S-phase) combined with a deletion of the CAP-Gly domain of Nip100. The number of cells in which the spindle moved from the m...

Confocal micrograph of a green alga, Penium margaritaceum. The cell wall is shown in green and the chloroplast is represented by autofluorescence. Honorable Mention, 2011 Olympus BioScapes Digital Ima...

Fluorescent micrograph of epithelial cells from the bladder wall. The cells were isolated immediately after collection of a urine specimen and are not fixed. The image was taken using a standard epi...

3HA-Bfa1 (red) localizes to both spindle pole bodies (SPBs) in anaphase in dyn1Δ cells with constitutive targeting of Tem1 to both SPBs. However, the constitutive presence of Tem1 on the SPBs impaire...

Figures 424 (upper) and 425 (lower) from Chapter 16 (Cytoplasmic matrix and cytoskeleton) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. The nucleus and adjacent the manchette rodent spermatids. The ...
