Electron micrograph of keratocyte or fibroblast lamellipodial actin network after unprotected extraction. All examples demonstrate frequent branching of actin filaments. Image corresponds to a singl...

Improved visualization of actin filament branching in lamellipodia. EM of keratocyte or fibroblast lamellipodial actin network after cytochalasin D treatment (0.2 μM for 30 min or 0.5 μM for 10 min)...

Confocal micrograph showing Shigella bacteria (pink) invading the intestinal lining. The bacteria infects the cells by high-jacking the cell's internal actin skeleton (green) to facilitate its entry i...

This video shows the apical (outside-facing) side of epithelia cells that form confluent tissues where each cell is tightly glued to its neighbors by circumferential junctions like bands of velcro. T...

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...

Figure 438 from Chapter 16 (Cytoplasmic matrix and cytoskeleton) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Two bundles of actin-rich stress fibers are apparent in this high magnification microgra...

Figure 439 from Chapter 16 (Cytoplasmic matrix and cytoskeleton) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Portion of a large stress fiber, composed of subunits of fibrous actin. This image is f...

The precise coupling of f-actin and parallel MT movements occurrs in all four zones of f-actin dynamic behavior: the lamellipodium,lamellum, convergence zone, and cell body. Primary cultures of newt ...
