Abstract

Overview

Biological systems are subjected to electromagnetic fields (EMFs) from both natural sources and technological devices. This study investigates the effects of static weak magnetic fields (WMFs) on biological systems, specifically looking at their impact on stem cell behavior and growth.

Findings

• WMFs, even those weaker than 1 mT, can influence biological outcomes.
• The research utilized the planarian regeneration model to show how WMFs affect stem cell proliferation and differentiation.
• The study highlights the role of reactive oxygen species (ROS) accumulation and the expression of heat shock protein 70 (Hsp70) in mediating these effects.
• Depending on the field strength, WMF exposure can either promote or inhibit new tissue formation in vivo.

Conclusion

This study suggests the potential of using WMFs as therapeutic tools to control mitotic activity in clinical applications, highlighting the significant yet nuanced role of weak magnetic fields in biological processes and their potential implications on health.
