Improved osteogenic differentiation by extremely low electromagnetic field exposure: possible application for bone engineering.
This in vitro study examined intermittent extremely low-frequency electromagnetic field (ELF-EMF) exposure (6 h/day) in human periodontal ligament mesenchymal stem cells during osteogenic differentiation. After 10 days, ELF-EMF-exposed cells showed increased proliferation and calcium deposition versus sham. Osteogenic markers (COL1A1, RUNX-2, OPN) were reported as upregulated with or without osteogenic medium, suggesting earlier and more efficient osteogenic differentiation under these conditions.
Key points
- The model system was human periodontal ligament mesenchymal stem cells (hPDLSCs).
- Cells received intermittent ELF-EMF exposure for 6 hours per day for 10 days and also across a 28-day differentiation period.
- Compared with sham, ELF-EMF exposure increased cell proliferation after 10 days.
- Compared with sham, ELF-EMF exposure increased de novo calcium deposition after 10 days.
- COL1A1 and RUNX-2 gene expression was reported as upregulated after ELF-EMF exposure.
- COL1A1, RUNX-2, and OPN protein expression was reported as upregulated after ELF-EMF exposure.
- The authors interpret the results as indicating earlier induction and enhanced osteogenic differentiation with ELF-EMF exposure.
