Synergic effects of extremely low-frequency electromagnetic field and betaine on in vitro osteogenic differentiation of human adipose tissue-derived mesenchymal stem cells.
This in vitro study tested 50 Hz, 1 mT ELF-EMF exposure (8 h/day for 21 days) and betaine (10 mM) during osteogenic induction of human adipose-derived mesenchymal stem cells. The authors report ELF-EMF decreased osteogenic differentiation and reduced RUNX2 and OCN gene expression compared with non-EMF conditions. Betaine increased osteogenic differentiation post-induction, and the combined betaine+EMF condition performed better than EMF alone, including higher calcium deposition.
Key points
- Cells were assigned to osteogenic medium alone, osteogenic medium plus betaine, osteogenic medium plus ELF-EMF, osteogenic medium plus betaine and ELF-EMF, and an untreated negative control.
- ELF-EMF exposure was 50 Hz at 1 mT, applied 8 hours daily for 21 days as a sinus wave.
- Osteogenic differentiation was assessed using Alizarin Red staining, alkaline phosphatase activity, calcium deposition, and RT-PCR for RUNX2 and OCN.
- RUNX2 and OCN expression in EMF-treated groups was reported to be significantly reduced versus non-EMF-treated groups.
- Calcium deposition was significantly higher in the betaine+EMF group compared with the other groups.
- Betaine was reported to increase osteogenic differentiation post-induction and partially improve RUNX2 expression relative to EMF alone.
