separate theoretical suggestions have been made that extracellular electric currents , whether from a biological or a nonbiological source , should be able to electrophorese intracellular molecules after being conducted through cell membranes into the interior of long single cells [ l.f. jaffe and r. nuccitelli ( 1977 ) annu . rev . biophys . bioeng . 6 , 445-476 ] or extended ensembles of cells coupled electrotonically by gap junctions [ m.s . cooper ( 1984 ) j. theor . biol . 111 , 123-130 ] .
