Migratory BT474 cells had much larger voltage-gated K+ (Kv) current density than non-migratory (control) BT474 cells. (A) BT474 cells from the upper chamber (control) and porous membrane (migratory) of Transwell were separated and subject to electrophysiological examination for Kv currents; (B) Cell currents are normalized with cell size to yield current density and plotted against voltages. Results are Inline graphic from 31−36 cells. *, significantly different (P<0.05) from control.
