Abstract:
The increasing use of microwave devices over recent years has meant the bioeffects of microwave exposure have been widely investigated and reported. However the exact biological fate of bone marrow MSCs (BM-MSCs) after microwave radiation remains unknown. In this study, the potential cytotoxicity on MSC proliferation, apoptosis, cell cycle, and in vitro differentiation were assayed following 2.856 GHz microwave exposure at a specific absorption rate (SAR) of 4 W/kg. Importantly, our findings indicated no significant changes in cell viability, cell division and apoptosis after microwave treatment. Furthermore, we detected no significant effects on the differentiation ability of these cells in vitro, with the exception of reduction in mRNA expression levels of osteopontin (OPN) and osteocalcin (OCN). These findings suggest that microwave treatment at a SAR of 4 W/kg has undefined adverse effects on BM-MSCs. However, the reduced-expression of proteins related to osteogenic differentiation suggests that microwave can the influence at the mRNA expression genetic level.
Insights
Microwave radiation at 4 W/kg did not significantly affect bone marrow mesenchymal stem cells (BM-MSCs) viability or apoptosis. However, it reduced mRNA expression for osteogenic differentiation markers, suggesting potential genetic-level impacts.
Area of Science:
- Biophysics
- Cell Biology
- Biotechnology
Background:
- Microwave device usage is increasing, necessitating research into biological effects.
- The impact of microwave radiation on bone marrow mesenchymal stem cells (BM-MSCs) remains unclear.
Purpose of the Study:
- To investigate the cytotoxicity of 2.856 GHz microwave exposure on BM-MSCs.
- To assess effects on proliferation, apoptosis, cell cycle, and in vitro differentiation.
Main Methods:
- Exposed BM-MSCs to 2.856 GHz microwave radiation at a specific absorption rate (SAR) of 4 W/kg.
- Assayed cell viability, proliferation, apoptosis, cell cycle, and in vitro osteogenic differentiation.
- Measured mRNA expression levels of key differentiation markers.
Main Results:
- No significant changes were observed in BM-MSC viability, cell division, or apoptosis.
- In vitro differentiation potential remained largely unaffected.
- A notable reduction in mRNA expression for osteopontin (OPN) and osteocalcin (OCN) was detected.
Conclusions:
- Microwave treatment at 4 W/kg SAR shows no overt adverse effects on BM-MSC viability or apoptosis.
- Reduced mRNA expression of osteogenic markers suggests microwave exposure may influence genetic expression related to differentiation.
