Transient physical disruption of cell membranes by electric pulses (or electroporation) has significance in biomedical and biological applications requiring the delivery exogenous (bio)molecules to living cells. We demonstrate that actin networks regulate membrane permeability during electroporation. Disruption increases uptake membrane-impermeable molecules such as propidium iodide Our experim...

The rate of filamentous actin (F-actin) depolymerization is proportional to the number of filaments depolymerizing and changes in the rate are proportional to changes in filament number. To determine the number and length of actin filaments in polymorphonuclear leukocytes and the change in filament number and length that occurs during the increase in F-actin upon chemoattractant stimulation, th...
