A, Images of scratch wound taken after 2, 3 and 5 days of electrical stimulation. By five days of stimulation DC, CC and DW covered the scratch in 48 hours, PEMF in 72 hours and control cells in 130 hours. Total magnification = 100x. B, Rate of movement per 24 hours after 2, 3 and 5 days of stimulation. The rate of movement was significantly greater for DC treated cells compared to the other waveforms after 2 and 3 days of stimulation (p<0.001), although by day 5 DC, DW and CC treated cells showed similar migration rates.
