Human osteosarcoma cells in response to ELF-MF: Morphological remodeling compared to cell proliferation.
This in vitro study exposed human osteosarcoma (MG-63) cells to 2 mT extremely low-frequency magnetic fields with sinusoidal, triangular, or pulsed waveforms under continuous (3 h) or fractionated (3 days) conditions. The authors report significant decreases in proliferation and shape index in exposed cells versus non-irradiated controls. Fractal dimension increased significantly after fractionated exposure, and the authors propose fractal dimension as a morphological index of ELF-MF–related structural remodeling.
Key points
- The study evaluates ELF-MF effects on human osteosarcoma MG-63 cells using cytoskeleton staining and proliferation assays.
- Exposure used a 2 mT magnetic field with sinusoidal, triangular, and pulsed waveforms.
- Two exposure regimens were tested: continuous 3-hour exposure and fractionated exposure across 3 consecutive days.
- Proliferation significantly decreased in exposed cells compared with non-irradiated controls.
- Cell shape index significantly decreased in exposed cells compared with controls.
- Fractal dimension significantly increased after fractionated exposure over 3 days.
- The authors report similar effects across the different waveforms tested.
