First Identification of the Effects of Low Frequency Electromagnetic Field on the Micromolecular Changes in Adipose Tissue-Derived Mesenchymal Stem Cells by Fourier Transform Infrared Spectroscopy.
This in vitro study exposed adipose tissue-derived mesenchymal stem cells to a continuous 50 Hz electromagnetic field at 1.5 mT for 24, 48, or 72 hours and assessed micromolecular changes using FTIR spectroscopy. The authors report the largest FTIR spectral differences versus control in nucleic acids and proteins after 24 and 48 hours. After 72 hours, they report no significant FTIR differences compared with control, and conclude the EMF was not neutral for these stem cells, particularly early in exposure.
Key points
- AT-MSCs were exposed to a continuous sinusoidal 50 Hz EMF at 1.5 mT.
- FTIR spectroscopy was used to assess micromolecular structure changes after 24, 48, and 72 hours.
- The largest reported spectral differences occurred after 24 and 48 hours of exposure.
- Reported differences were mainly in the fingerprint region associated with nucleic acids and proteins.
- After 72 hours, the study reports no significant FTIR spectral differences versus control.
- The authors interpret FTIR changes as preceding morphological manifestations.
