Abstract

Many different pulsed electromagnetic field (PEMF) devises have been clinically used to stimulate healing processes, but many procedures are still without supporting basic research data. The aim of this study was to investigate a new modified pulsed electromagnetic field therapy: electromagnetic transduction therapy (EMTT). EMTT is technically based on high-intensive PEMFs with a magnetic field strength between 80 and 150 mT. The effect of EMTT for a 10-min session three times a week on human bone marrow mesenchymal stem cells (MSCs) was evaluated by assessing cell viability, gene expression of bone regenerative factors and VEGF-A (vascular endothelial growth factor) secretion after 7 and 14 days of treatment. No negative or toxic effects of EMTT on MSCs were observed in the applied test frame. The VEGF-ELISA at day 7 of EMTT treatment with 80 mT showed a significant higher VEGF concentration compared to untreated control group. In conclusion, high-intensive electromagnetic impulses showed no harmful effects on MSC cultures in our study. The enhancement of the proangiogenic factor VEGF in MSCs on day 7 indicates a substantial role in cell-stimulating effect of EMTT. Further and studies should differentiate specific stimulating and regenerating effects of EMTT impulses in soft tissue engineering. Specific electromagnetic characteristics have to be determined to optimize electromagnetic treatment options in orthopedic surgery and traumatology and soft tissue treatment options.

摘要

许多不同的脉冲电磁场(PEMF)设备已在临床上用于刺激愈合过程,但许多程序仍然没有支持基本研究数据。本研究的目的是研究一种新的改良脉冲电磁场治疗方法:电磁转换治疗(EMTT)。EMTT 在技术上基于高强度的 PEMF,磁场强度在 80 至 150 mT 之间。通过评估细胞活力、骨再生因子的基因表达和治疗 7 天和 14 天后 VEGF-A(血管内皮生长因子)的分泌,评估 EMTT 对人骨髓间充质干细胞(MSCs)的 10 分钟/次、每周 3 次的治疗效果。在应用的测试框架中,没有观察到 EMTT 对 MSCs 的负面或毒性影响。在 EMTT 治疗 80 mT 的第 7 天进行的 VEGF-ELISA 显示,VEGF 浓度明显高于未处理的对照组。总之,在本研究中,高强度电磁脉冲对 MSC 培养物没有不良影响。第 7 天 MSCs 中促血管生成因子 VEGF 的增强表明 EMTT 在细胞刺激作用中具有重要作用。进一步的研究应区分 EMTT 脉冲在软组织工程中的特定刺激和再生作用。为了优化矫形外科和创伤学以及软组织治疗方案中的电磁治疗选择,必须确定特定的电磁特性。
