High-specificity protection against radiation-induced bone loss by a pulsed electromagnetic field.

This study reports a noninvasive pulsed-burst electromagnetic field (PEMF) approach intended to protect against radiotherapy-induced bone loss. A 15 Hz, 2 mT PEMF waveform is described as producing distinctive calcium oscillations in osteoblasts and inhibiting radiation-related bone loss while not affecting other…

[Genic and non-genic regulation of low frequence pulsed electromagnetic fields on osteoblasts differentiation].

This in vitro study exposed rat calvarial osteoblasts to 50 Hz, 0.6 mT pulsed electromagnetic fields for 1.5 hours and measured early differentiation-related markers over 0–12 hours. The abstract reports increased ALP activity at 3 hours and time-dependent changes in ALP, Runx2, and OSX transcription and Runx2/OSX…

[Effects of static magnetic field at different times on the proliferation and differentiation of osteoblasts in vitro].

This in vitro study exposed newborn rat calvarial osteoblasts to a 3.9 mT static magnetic field for varying durations (0–4 hours). The authors report increased cell proliferation and markers of osteoblast differentiation and mineralization versus control, including higher ALP activity, calcium content, and…

[Time effect of sinusoidal electromagnetic field on enhancing the maturation and mineralization of osteoblasts in vitro].

This in vitro study exposed newborn rat calvarial osteoblasts to 50 Hz sinusoidal electromagnetic fields at 1.8 mT for different daily exposure times (0.5–3.0 h). The authors report inhibited osteoblast proliferation at longer exposure times, alongside increased differentiation markers (ALP activity) and…
