Jan 1, 2026
This ex vivo 3D hamstring tendon explant culture study exposed samples from nine donors to pulsed electromagnetic fields (PEMF) for 21 days, eight hours per day. The authors report increased expression of tendon-related markers (scleraxis, collagen I and VI) and tenogenic differentiation-related players (c-Fos and…

This animal experimental study exposed chicken embryos (CAM) continuously to 2.4 GHz Wi-Fi at an average power density of 300 μW/m2 for 9 or 14 embryonic days. H&E staining reportedly showed no significant structural differences in large vessel walls versus controls. However, special staining reported decreased…

Jan 1, 2021
This animal and in vitro study evaluated a composite osteochondral scaffold with bone marrow mesenchymal stem cells (BMSCs) combined with low-frequency electromagnetic field (EMF) stimulation. The authors report that EMF promoted BMSC proliferation and chondrogenic differentiation in vitro, partly via PI3K/AKT/mTOR…

Jan 1, 2021
This clinical and histological study evaluated a combined electromagnetic fields and negative pressure treatment (V-EMF) for stretch marks and skin hypotonia. Sixty women aged 25–45 underwent 6 or 8 weekly sessions, with documentation via pictures, patient satisfaction, and biopsies. The authors report histological…
A single-pulsed electromagnetic field enhances collagen synthesis in tendon cells.

Jan 1, 2020
This in vitro study reports that a single pulsed electromagnetic field (0.2 Hz) increased expression of tenogenic genes and reduced expression of a matrix-degradation/inflammatory gene (Mmp1) in tendon cells. After 5 days of exposure (3 min/day), collagen type I and total collagen synthesis protein levels were…
Efficacy of pulsed electromagnetic fields and electromagnetic fields tuned to the ion cyclotron resonance frequency of Ca on chondrogenic differentiation.

Jan 1, 2019
This in vitro study compared commonly used pulsed electromagnetic field (PEMF) exposures with electromagnetic fields tuned to satisfy the ion cyclotron resonance (ICR) condition for calcium. After 3 weeks, the calcium ICR condition was associated with increased glycosaminoglycans and type II collagen synthesis and…

Jan 1, 2017
This animal study evaluated whether 50 Hz EMF exposure enhances wound healing after transplantation of human epidermal stem cells (ESC) seeded in collagen sponge scaffolds. Thirty-six nude mice with full-thickness wounds were assigned to control, ESC-only, or ESC+EMF groups (50 Hz, 5 mT, 60 min/day for 20 days). The…
Electromagnetic fields counteract IL-1β activity during chondrogenesis of bovine mesenchymal stem cells.

Jan 1, 2015
This in vitro study examined whether electromagnetic fields (EMFs) influence chondrogenic differentiation of bovine mesenchymal stem cell pellets, with and without the inflammatory cytokine IL-1β. The authors report EMFs had limited effects on chondrogenesis in the absence of inflammation, but in the presence of…
Effects of low frequency electromagnetic fields on the chondrogenic differentiation of human mesenchymal stem cells.

Jan 1, 2011
This in vitro study examined whether extremely low-frequency magnetic fields affect chondrogenic differentiation of human mesenchymal stem cells in pellet culture. Cells exposed for 3 weeks to a homogeneous sinusoidal 5 mT magnetic field showed increased collagen type II expression (significant at passage 6) and…

Jan 1, 2009
This concise review discusses radiofrequency (RF) dermatologic devices used for nonablative skin rejuvenation and related indications. It characterizes RF effects on tissue as primarily thermal, aiming to heat targeted skin layers to trigger collagen changes and subsequent remodeling. The abstract cites preliminary…
Histologic evaluation of thermal capsulorrhaphy of human shoulder joint capsule with monopolar radiofrequency energy during short- to long-term follow-up.
