evidence marshaled in support of this hypothesis includes disappearance of microvilli and other microprotrusions during cell spreading , increase in protrusive activity of uncontacted regions of the cell surface during contact inhibition of cell movement , antagonism between blebbing and spreading , accelerated protrusive activity at the leading edge upon abrupt retraction of the trailing edge , surface flow during bleb formation , and antagonism between various protrusive activities associated with cell movement and cytokinesis .
