In an in vitro wound-healing model, exposure to an extremely weak 1 GHz EMF activated human fibroblast migration. The EMF also increased fibroblast proliferation as measured by [3H]thymidine incorporation, and increased HFGF1 expression after exposure.

Abstract

The aim of this study was to test if an extremely weak 1 GHz electromagnetic field (EMF), known to be in resonance with clusters of water molecules, has biological effects on human fibroblasts. We demonstrated that in an in vitro model of wound healing, this EMF can activate fibroblast migration. [(3)H]thymidine incorporation experiments demonstrated that the EMF could also activate fibroblast proliferation. Activation of the expression of human fibroblast growth factor 1 (HFGF1) after EMF exposure showed that molecular wound healing pathways are activated in response to this water-resonant EMF.
