the topographic distribution of contractile filaments beneath the plasma membrane visualized by correlated light- and electron microscopy of dnaase i-injected cells establishes the importance of the membrane-bound filamentous layer for three major aspects of streaming : ( 1 ) streaming originates by local contractions of a cell membrane-associated filament layer at the uroid and/or retracting pseudopods , creating a pressure flow .
