Effects of a low-intensity electromagnetic field on fibroblast migration and proliferation. med./bio.

Published in: Electromagn Biol Med 2011; 30 (2): 80-85

Aim of study (acc. to author)

To test if an extremely weak 1 GHz electromagnetic field, known to be in resonance with clusters of water molecules, has biological effects on human fibroblasts.

Main outcome of study (acc. to author)

The data showed that in an in vitro model of wound healing, this electromagnetic field can activate fibroblast migration and cell proliferation. Activation of the gene expression of human fibroblast growth factor 1after exposure showed that molecular wound healing pathways are activated in response to this water-resonant electromagnetic field.
