Abstract

Systems and methods are provided for migrating cells implanted or endogenous in tissue. The system may include first and second delivery electrodes configured for insertion in tissue and a direct current (DC) power source operatively coupled to the first and second delivery electrodes. The system further may include a programmable controller operatively coupled to the DC power source, wherein the programmable controller is programmed to direct the DC power source to deliver an electric field between the first delivery electrode and the second delivery electrode at a stimulation to nonstimulation ratio sufficient to cause the cells to migrate within tissue selectively.
