Fig. 3. Inhibition of ecto-ATPases significantly enhanced galvanotaxis of hTCEpi cells. (A) Directedness and migration speed of cells treated with 100 ÁM of ARL 67156 at the EF strength of 30 mV/mm. (B) Black and red lines indicate trajectories of cells that migrated toward the cathode and the anode side, respectively. n=50 cells for each group. Statistical analysis was performed. Data represented as mean ▒ SEM. *p< 0.05.
