| Summary: | The vascular system is primarily responsible for orchestrating the underlying healing processes to achieve tissue regeneration, thus the promotion of angiogenic events could be a useful strategy to repair injured tissues. Among several approaches to stimulate tissue regeneration, non-invasive devices are currently widely diffused. Complex Magnetic Fields (CMFs) are innovative pulsed multifrequency electromagnetic fields used for their promising results in clinical applications, such as diabetic foot treatment or edema resorption. Nevertheless, few papers are available demonstrating the biological mechanisms involved. In this paper, in order to understand CMFs’ capability to promote angiogenic events, Regenerative Tissue Program (RTP) was applied to an in vitro Endothelial Cells (ECs) model. ECs were stimulated with (I) 2 RTP consecutive cycles, (II) with an interval of 8 h (T0 + T8), or (III) 24 h (T0 + T24) from one cycle to another. Results demonstrate that (I) extracellular matrix degradation is promoted through matrix metalloproteinases 2 and 9 modulation, leading to an increased cell migratory capability; (II) CMFs support EC growth, activating Integrin β1-Erk-Cdk2 pathway and sustaining G1/S transition; (III) vessel morphogenesis is promoted when CMFs are applied. In conclusion, the promising clinical results are supported by in vitro analyses which evidence that main angiogenic events are stimulated by CMFs. |
