Figure 2.

Graphics showing the colocalization rate and relocation of proteins during electrotaxis. The colocalization rates of pNHE3/ß-actin and of NaKA/vinculin with and without EF exposure in cathode (Calvaria)- and anode (SaOS-2)-directed cells (A). The EF-induced relocation of pNHE3, NaKA, ß-actin, and of vinculin to or from the leading edge of a cell during cathode (Calvaria)- and anode (SaOS-2)-directed motility (B). Error bars represent the SEM for 16-31 cells from three separate experiments (*P < 0.05 compared to the control -wothout EF-).
