The researchers noticed that electricity enabled the former to heal three times faster than the latter. “We were able to show that the old hypothesis about electric stimulation can be used to make wounds heal significantly faster,” said Asplund.
According to the study authors, an electric field act as a guide to skin cells. In the absence of current, the cells move randomly, and therefore, the process of healing is slow. However, when cells are electrically stimulated, they all align in one direction and migrate fast toward the damaged site, eventually making a wound heal more quickly.
Moreover, no side effects were noticed on the cultured wounded cells due to the electric stimulation.
