Proximity of excitatory and inhibitory axon terminals adjacent to pyramidal cell bodies provides a putative basis for nonsynaptic interactions. Video sequence made up of 14 consecutive confocal micros...

Metaphase Kinetochore Dynamics: In this HeLa cell, which is expressing both a kinetochore marker (EGFP-CENP-B) and a centrosome marker (Venus-centrin), one can visualize the dynamic nature of kinetoch...

This HeLa cell is expressing two fluorescent proteins, including EGFP-CENP-B, a fluorescent protein that marks kinetochores (seen as paired dots oriented parallel to the x-axis and attached to opposit...

In this HeLa cell, which is expressing both a kinetochore marker (EGFP-CENP-B) and a centrosome marker (Venus-centrin), one can visualize the dynamic nature of kinetochore movements during metaphase a...

This HeLa cell, which is expressing both a kinetochore marker (EGFP-CENP-B) and a centrosome marker (Venus-centrin), has been depleted of the spindle assembly checkpoint protein Mad2. In the absence o...

Disruption of the Actin Cytoskeleton with Cytochalasin D. U2OS human osteosarcoma cells were transduced with 'Cellular Lights' Actin-RFP (Actin-red fluorescent protein) and Cellular Lights MAP4-GFP (...

Dynamics of membrane ruffling (top) and intracellular vesicle motion (bottom) in a cSrc-transfected COS-7 cell. Images were collected with a Bessel Beam Microscope using two photon excitation. This f...

Views parallel and perpendicular to the mitotic plane of chromosome dynamics in a dividing LLC-PK1 cell, with a plane (left) cutting through one daughter cell during anaphase to show an interior view ...

Live toxoplasma gondii cell line stably expressing EGFP fused to the beta II tubulin gene. Image was collected using ABI Deltavision on an Olympus PSF microscope with excitation at 450-490 nm and emis...

Chromosome dynamics in a dividing LLC-PK1 cell. Images were collected with a Bessel Beam Microscope using two photon excitation. This form of microscopy provides extraordinary 4D resolution of the se...
