A high resolution image of toxicysts in the cytoplasm of cross sectioned non-dividing Didinium. Toxicysts (extrusomes) are multilayered cylinders that are discharged from the cytopharynx region during...

Fluorescent micrograph of a Xenopus melanophore, showing microtubules (green), microtubule plus ends (red) and nucleus (blue). Honorable Mention, 2011 Olympus BioScapes Digital Imaging Competition®...

The organization of the actin cytoskeleton in an early Drosophila melanogaster embryo (cycles 9-12) syncytium can be observed by time lapse imaging of embryos expressing a GFP-tagged actin binding pro...

NIH 3T3 cell transfected with EGFP-VASP. VASP is localized to the focal adhesions and is also present along the protruding leading edge. VASP only hightlights the portions of the periphery that are ...

The tip of the trichocyst does not expand but remains nail shaped and remains bound to the elongated shaft. TEM taken on 6/7/88 by C. Schroeder with Zeiss 10A operating at 80kV. Neg. 19,800X. Bar = 0....

This sequence shows actin nucleation on the dorsal surface of an advancing lamellipodium. Small actin nucleations have been termed inductipodia in nerve growth cones, since they can be induced by late...

Transmission electron micrograph of a representative sertraline-treated chc1 mutant cell. CHC1 encodes clathrin heavy chain, which trimerizes to form triskelia that coat vesicles. The vacuolar fragmen...

A time lapse experiment of Saccharomyces cerevisiae expressing GFP-tagged ESP1. ESP1 is essential for dissolving the cohesins that hold the sister chromatids together. ESP1 activation results in prop...

Movie shows actin cytoskeleton in Nck-deficient cells rescued with Nck1 after stimulation with PDGF-B. In the presence of Nck1, PDFG-B stimulation induced highly dynamic peripheral membrane ruffling. ...

A time lapse experiment of Saccharomyces cerevisiae expressing GFP-tagged ESP1. ESP1 is essential for dissolving the cohesins that hold the sister chromatids together. ESP1 activation results in prop...
