Osteogenic effect of electromagnetic fields on stem cells derived from rat bone marrow cultured in osteogenic medium versus conditioned medium in vitro.
This in vitro study tested whether ELF-EMF exposure (50 Hz, 1 mT; 30 min/day) influences osteogenic differentiation markers in rat bone-marrow-derived stem cells cultured in osteogenic medium or in human adipose-stem cell-conditioned medium. The OM + EMF condition showed higher ALP activity and higher Runx2 and Ocn expression at day 21 compared with other groups. The authors conclude that EMF and osteogenic medium together had a synergistic effect on osteogenic gene expression in this cell model.
Key points
- Study design was in vitro using rat bone-marrow-derived stem cells cultured under different media conditions.
- Exposure was extremely low frequency EMF at 50 Hz and 1 mT for 30 minutes per day.
- ALP activity was highest in the osteogenic medium plus EMF group compared with other groups.
- Runx2 expression increased in the conditioned medium plus EMF group versus conditioned medium alone and positive control, and was highest in osteogenic medium plus EMF at day 21.
- Ocn expression was reported as not affected by conditioned medium or EMF alone, but was higher in osteogenic medium plus EMF than positive control at day 21.
- Outcomes included ALP activity, alizarin red staining, and RT-PCR for osteogenic markers.
