WebJan 1, 2014 · As expected, compared with the controls the PIP 2-upregulated spread cells (including HUVECs and THP-1-derived macrophages) were more difficult to bleb upon … WebSep 22, 2010 · Abstract. Cells remodel their plasma membrane and cytoskeleton during numerous physiological processes, including spreading and motility. Morphological changes require the cell to adjust its membrane tension on different timescales. While it is known that endo- and exocytosis regulate the cell membrane area in a timescale of 1 h, faster ...
