The image depicts a live neutrophil cell showing the level of activation of the signaling protein Cdc42, a member of the Rho family of small guanosine triphosphatase (GTPase) proteins which regulates ...

Localization of Arp2/3 complex in a fibroblast lamellioidia. Staining with p21 antibody (green) and TRIT-phalloidin (red) shows Arp2/3 complex highly enriched in lamellipodia. CIL 24796 shows an immu...

The f-actin staining in the lamella of a cultured fibroblast shows common features of adherent cells on a flat substrate. The dominant f-actin organization is in the form of stress fibers, linear bun...

Multiple branching of actin filaments in lamellipodia of vertebrate fibroblasts. This image shows a local enlargement of the leading edge shown in overview in CIL 24788. Image corresponds to Figure 1...

Shown are a normal human fibroblasts stained for lamin A (red), a major component of the nuclear lamina. Other images in this group show the envelope abnormalities that occur in HGPS patients carryin...

Confocal microscope image of a mouse fibroblast cell about to divide. The nuclei are stained red, and the actin and tubulin filaments of the cytoskeleton, forming the internal framework, are stained g...

High voltage (1MeV) transmission electron microscopy image of an isolated metaphase chromatid pair from a mouse A9 cultured cell, showing the fiber-like structure and several pieces of attached membra...

High voltage (1MeV) transmission electron microscopy image of an isolated metaphase chromatid pair from a mouse A9 fibroblast, showing the fiber-like structure. The image was taken with a specimen til...

High voltage (1MeV) transmission electron microscopy image of an isolated metaphase chromatid pair from a mouse A9 cell, showing the fibrous structure. The image was taken with a specimen tilt of 55 d...
