title: Bioelectric Field Enhancement: The Influence on Membrane Potential and Cell MigrationIn Vitro.
abstract: Objective:The extracellular matrix consists of critical components that affect fibroblast polarization and migration. The existence of both intrinsic and extrinsic electrical signals that play essential roles in the development, physiology, regeneration, and pathology of cells was discovered over a century ago. In this study, we study how the Bioelectric Field Enhancement (BEFE) device and its generated electromagnetic field (EMF) by continuous direct current (DC) significantly affect the membrane potential and cell migration of fibroblastsin vitro.Approach:This is an experimental analysis of membrane potential and cell migration of murine fibroblasts when grown in treated media that has been reconstituted with an aqueous solution that has been exposed to an EMF, which is generated by this device versus fibroblasts grown in identically prepared control media that has not been exposed to the EMF.Results:The growth of fibroblasts in the treated media shows a strong percent change in polarization of the plasma membrane and significant increase in cell migration compared to control groups.Innovation:These experiments show the potential for an adjunct wound care therapy using a continuous DC EMF application through a medium of water.Conclusion:Growth media that was reconstituted with an aqueous solution that had been exposed to this DC derived EMF shows significant changes in cell polarity and cell migration of fibroblastsin vitro. The BEFE device has shown enhanced chronic wound healing in anecdotal reports from patients globally for decades when used as a footbath/bath and could lead to a novel EMF application in wound healing.
