and other cells, such as tumor cells interact with the endothelium under various blood flow conditions. It is shown that the interactions are influenced by cell–cell adhesion properties, shear stresses due to the flow field and can also be modified by the cells microrheological...
2. Note that some zoologists also use the term “pseudopodia” or “pseudopods” rather generally to refer to a variety of cell‐surface protrusions. These include the different types of protrusions described here as playing a role in amoeboid motility, but also the long extended processes th...
The process used by cells like white blood cells to engulf microorganisms with pseudopods is A. exocytosis. B. phagocytosis. C. facilitated diffusion. D. osmosis. Sodium ions are moving with their concentration gradient with the use of a protein channel across a plasma membrane. Determine the ...
Figure 5 is a simplified summary diagram of the synaptic organization of the primate retina. Each cone in the primate retina makes connections with two midget bipolar cells, one that makes invaginating-type junctions and another that make flat junctions (Figure 5, left). In the central region...
The interaction of Yersinia with host surface integrins induces activation of the cytoskeleton and the rearrangement of actin into pseudopods that engulf the bacteria (Krukonis and Isberg, 1997). A number of microbial pathogens, including B. pertussis, Coxiella burnetti, E. coli, Histoplasma capsula...
In the first step of migration, the lamellar pseudopods of the cells need to form adhesion to the substrate in order to have a point of support to pull the cells [30]. Therefore, Western blot and immunofluorescence techniques were used here to detect paxillin, a marker of FA, in order ...
The contributions of the whole trajectory can eventually comprise a quantitative signature in which correlated events appear more or less frequently than would be expected by chance (shown below the main diagram, with blue indicating a higher (and red a lower) likelihood. The calculation of the ...
At the 96 h time point, cells in melatonin showed plenty of pseudopods and more red fluorescence of actin filaments than those in the standard medium. With the increase in melatonin concentration, cell numbers were significantly decreased (Fig. 2). Figure 2 Effect of melatonin on ALCs’ ...
The process used by cells like white blood cells to engulf microorganisms with pseudopods is A. exocytosis. B. phagocytosis. C. facilitated diffusion. D. osmosis. The movement of water across a semi-permeable (selectivelypermeable) membrane is: a. diffusion. b. osmosis. c. endocytosis....
The other similarity among these experiments is the actual adhesion process once the cells are in contact with a surface. Once the cells settle to the surface, the platelets, as well as the EC, then initiate adhesion by extending pseudopods. The central portion of the cell then follows these...
