Human keratinocytes migrate to the negative pole in direct current
We find that keratinocytes migrate randomly on collagen in fields of 5 mV/mm or less, but in larger fields they migrate towards the negative pole of the field, exhibiting galvanotaxis. Since these cells have an average cell length of 50 µm, this implies that they are able to detect a voltage gradient as low as 0.5 mV along their length.
