Time-lapse of a CHO.K1 cell cotransfected with very low levels of GFP-MIIA (myosin IIA, green) and paxillin (magenta). Yellow arrowheads mark paxillin-containing adhesions that disassemble concomitant...

Freeze fracture replicas of zonula occludens junctions from the large intestine of a tadpole (upper) and intestine of a post-metamorphic toad (lower). The occluding junction appears as a meshwork of...

Differential interference microscopy (DIC) image of PtK1 cell (marsupial kidney epithelial cell expressing dominant-negative Rac1(T17N). Live cells were used to study microtubule dynamics using X-rhod...

Scanning electron micrograph showing tentacles on the head of a Hydra viridis. Epithelial cells located at the base of the tentacle are in a flat, contracted state. Cell distal to the head of the H. v...

Gallbladder wall of a human patient with gallstones. The top layer is composed of highly polarized epithelial cells with microvilli partially visible at the apex and dark nuclei at the base. Below ...

Distribution of Nup133 (a component of the Nup107-160 nucleoporin complex, red) and CENP-B (kinetochores, green) in dividing Hela cells. See Fig 2A in Orjalo et al. 2006 Mol Biol Cell 17:3806-3818.

Nup133 (a component of the Nup107-160 nucleoporin complex, red) localizes to spindle poles and kinetochores while NuMA localizes to spindle poles (green) in prometaphse Hela cells. See Fig 2D in Orjal...

The first image in this multi-image tiff file is a stimulated emission depletion image (STED) of microtubules in a Drosophila S2 cell. The second image is the corresponding diffraction limited image ...

Transmission electron micrograph of a microvilli at the apex of a mouse intestine. Image made available by James D. Jamieson and the Department of Cell Biology, Yale University School of Medicine.

Fluorescent micrograph showing a section of human appendix infected with the measles virus. The measles virus is shown in green, cytokeratin is shown in red, which marks the epithelium, and Dapi stain...
