This in vitro study tested a specific extremely low frequency electromagnetic field (ELF-EMF) on three human osteosarcoma cell lines grown in 2D and 3D spheroid models. The abstract reports that ELF-EMF exposure inhibited proliferation and altered mitochondrial metabolism in the cancer models. It also reports…

This in vitro study exposed three ccRCC cell lines and a healthy kidney cell line (HEK293) to 50 Hz ELF-EMF at 4.5 mT for 30 minutes daily over 5 days. The authors report exposure-associated changes in expression of several genes (names not fully visible in the abstract), with differences between primary…

This in vitro study exposed B16-BL6 melanoma cells to a time-varying EMF modeled after intercellular calcium-wave firing patterns. The abstract reports a 50.3% reduction in viable cells after a single 40-minute exposure and microscopy findings consistent with apoptosis and nuclear fragmentation versus control. The…

This in vitro study characterized spinning oscillating magnetic field (sOMF) stimulation patterns that the authors report can induce cytotoxicity in two types of human glioma cells. The reported effect was linked to a critical rise in superoxide, and was reversed by the antioxidant Trolox, suggesting ROS involvement.…

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…

This in vitro study exposed dental pulp mesenchymal stem cells to 50 Hz pulsed electromagnetic fields at 0.5 or 1 mT for 20 or 40 minutes per day over seven days. Cell survival/proliferation was generally higher than control across exposure groups, except for the 40 minutes/day at 1 mT condition. DMP1 expression was…

This in vitro study describes a microfluidic device integrated with a radiofrequency exposure system to enable on-chip monitoring of cellular responses under a 1.8 GHz field. Using human amniotic epithelial cells, the authors report field-intensity-associated increases in protrusions/filopodia, changes in…

This in vitro study compared continuous versus intermittent 16 Hz ELF-PEMF exposure strategies in osteoprogenitor (SCP-1) cells. Intermittent exposure (10 min every 8 h) was reported to enhance cell numbers and osteogenic function relative to continuous daily exposure (30 min every 24 h). The authors report increased…

This in vitro study assessed 50 Hz, 100 G extremely low-frequency EMF in combination with temozolomide and radiation in T98 glioblastoma cells grown as monolayers and spheroids. Radiation plus EMF increased apoptosis-related gene expression, while temozolomide plus EMF increased autophagy marker expression compared…

This in vitro study exposed two human breast cancer cell lines to a 50 Hz ELF-EMF (20 mT) for 3 hours/day for up to four days. The authors report reduced viability and apoptosis-related findings in MDA-MB-231 cells, with no significant viability change in MCF-7 cells. Cell-cycle effects differed by cell line,…

This in vitro study examined whether 96-hour exposure to 50 Hz ELF-EMF affects expression of human endogenous retroviruses (HERV-H, HERV-K, HERV-W) in SK-MEL-37 human melanoma cells. Cells were continuously exposed at 1.5 or 3 mT and HERV env mRNA levels were measured by qPCR. The authors report significant…

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…

This in vitro study examined how a 20 mT static magnetic field and a 20 mT 50 Hz electromagnetic field affect mesenchymal stem cells under conditions involving ROS and acidic pH. The authors report increased ROS and antioxidant-response markers (Nrf2, SOD2, GST) across SMF, EMF, and combined exposures, with…

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.…

This in vitro study exposed human adipose-derived mesenchymal stem progenitor cells to an alternating EMF generated by the IteraCoil device at 0.05 and 1 kHz. The authors report that EMF exposure was associated with osteoblastic differentiation in the absence of exogenous pro-osteogenic supplements, assessed by…

This in vitro study examined how low-frequency electromagnetic fields (LF-EMF) at different magnetic flux densities influence skeletal myogenesis in C2C12 cells. The authors report that 2.0 mT LF-EMF activated cells and increased PAX7, while 1.5 mT increased MyoD and myogenin expression. They conclude that different…

This in vitro study evaluated short-term extremely low frequency electromagnetic field (ELF-EMF) exposure and silver nanoparticles (AgNPs), alone and combined, for antibacterial effects and apoptosis induction in MCF-7 breast cancer cells. The authors report time-dependent reductions in bacterial viable counts, with…
