Evaluation of Magnetic Stimulation on Oral Tissue by Genomic Response

This experimental study describes extremely low magnetic fields (ELMF) of 0.4T and 0.17Hz stimulated mouse osteoblast-like cell proliferation at early stage, and differentiation to mature osteoblasts, whereas fibroblasts did not show significant differences in proliferation by the exposure. These results suggested that osteoblasts have specific response on the magnetic fields, and then bone formation could be accelerated through stimulated osteoblasts by ELMF. Microarray gene analysis revealed that ELMF stimulated genes expressions were extracted.
