The trajectories of cell movement depend on the size, rhythm, and direction of long series of pseudopods. These pseudopod properties are regulated by internal factors such as memory of previous directions and by external factors such as gradients of chemoattractants or electric currents. Here a ...
Shows that the Par polarity complex, previously known to establish apical–basal polarity, drives front–rear polarization in migrating keratinocytes; blocking Par complex function increases random migration and inhibits chemotaxis, probably by interfering with microtubule stabilization at the leading edge ...
The transition from vegetative to floral state or reproductive development is a critical phase in the life cycle of higher plants, and the products of flowering are an integral part of the human diet, cultural integrity and global economies. Cut flowers

SCAR-SA cells are excessively long and polarized, with no pseudopod splitting. SCAR-SD cells generate new pseudopods, but they are small and uncoordinated, yielding a rounded morphology. Phosphorylation Mutants and Pseudopod Dynamics Dictyostelium is unusual in that cells are able to survive and ...
Each dot represents the length of one pseudopod. 176 sperm with poor motility and 181 sperm with normal motility were analysed. (f–i) Microscopic images indicating that the sperm derived from spe-8(lf) males display increased distribution in the uterus by the vulva of fog-3(lf) females ...

mesenchymal migration through 3D fibrillar ECM, as monitored for HT1080 fibrosarcoma and MDA-MB-231 breast carcinoma cells by submicron-resolved imaging, is mediated by several types of proteolytic structures rich in filamentous actin, ß1 integrin, and MT1-MMP with distinct location and function....
pneumoniae GFP cells were injected into the blood stream of mice (very small round green particles), and blood is stained with TRITC-dextran (red). White arrows point to CD11c DC extending small pseudopod into the blood stream. Download: Download Acrobat PDF file (5MB) Document S2. Article ...
effort, as, for the first time, we now have a transcriptome-wide description of the ingredients required to bring fetal-like regenerative function back into adult epicardium. First, the regenerative human epicardium may drive angiogenesis throughNRP2,VEGFA,CXCL14andSLIT3with adult endothelial cells...
