... aberrant distribution of F-actin in fluorescence cell staining and an increased amount of cytoskeleton-associated actin. Excessive pseudopod formation was also noted in cosA − cells facing chemoattractant gradients. Expressing cosA or its human counterpart mCostars eliminated abnormalities of cosA − cells...

...Peter J. M. Van Haastert Chemotaxis is one of the most fascinating processes in cell biology. Shallow gradients of chemoattractant direct the movement of cells, and an intricate network of signalling pathways somehow instructs the movement apparatus to induce pseudopods in the direction...

... of the retracting pseudopodia in wild-type cells (right images in Fig. 6A,B ), where F-actin also accumulated (left images in Fig. 6A,B ). Fig. 6A′ and 6B′ show the time-courses of traction stresses under the tips of each pseudopod, with the lengths shown in Fig. 6A,B . The magnitude of the traction stresses...

... Crac -GFP at the leading edge in a cAMP gradient. We show that cAMP determines the probability of patch formation (half-maximal effect at 0.5 nM cAMP) but not the size, lifetime or intensity of patches, indicating that patches are self-organizing structures. A pseudopod is extended from the area...

...Ivan R. Nabi ABSTRACT Polarization of the motile cell is associated with the formation of a distinct plasma membrane domain, the pseudopod, whose stabilization determines the directionality of cell movement. The rapid movement of cells over a substrate requires that an essential aspect of cell...

Using video-enhanced microscopy, we directly visualized exocytosis of single vesicles in living Physarum plasmodia migrating on a substrate. Vesicles containing slime, the plasmodial...
