An additional measurement of the potential between the record- ing electrode and the reference in the bath was taken mm away from the surface of the wound. As healing nears completion, most of the potential drop between the subintegumentary region and the bath occurs across the epithelium that covers the wound. vitro, then the normal lateral wound fields that were ob- served here should be of sufficient strength to have an effect on their migration.

A wound ca. mm in diameter was made in the middle hindlimb digit tip. and the transepithelial potential of the skin was measured at 0, , , 1, and 2 mm from the edge of the wound. The slope of the potential difference between the edge of the wound and a point mm away from the wound is taken as the lateral wound potential. In this instance, the lateral wound potential was mV/mm (the negative sign con- veys the fact that the polarity of this field is opposite that of the normal wound potentials)..
