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...

The flagellar pocket of a Trypanosoma brucei bloodstream form cell, with short flagellum. The image shows a new flagellum starting to grow from the flagellar pocket, in preparation for the next cell d...

Transmission electron micrographs showing details of nuclear pores in thin sections of an erythroblast (above) and endothelial cell (below). Pores appear to be filled with dark staining material in th...

Longitudinal section of somatic cilia showing the axoneme, basal body, and attached fibrous and microtubular elements. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alco...

Upper panel shows a transmission electron micrograph featuring the nuclear envelope with the nuclear lamina seen here as a uniform layer between the inner nuclear membrane and more darkly staining blo...

Transmission electron micrograph of ventricle tissue of a mouse cardiac muscle. This image shows the various areas of a muscle fiber. The Z lines are the very dark borders that link sarcomeres. Th...

Transmission electron micrograph of nucleus showing the characteristic features of glutaraldehyde fixation introduced as a primary fixative in 1962 and since used routinely. Chromatin appears differen...

High resolution image of a myoneme of Opercularia coarctata. Such fibrous bundles are known to be composed of centrin, a filament that contracts when exposed to calcium. The ER is closely associated w...

Transmission electron micrograph illustrating the unusually prominent fibrous nuclear lamina (arrows) seen in many invertebrates such as this leech ganglion cell. From Fawcett (1966) Am J. Anat. 119:...

Transmission EM of cotyledons of wildtype Arabidopsis thaliana grown in the dark showing the characteristic quasi-crystalline prolamellar bodies. Other images in this group show the development of typ...
