Since scant information is available about the side effects of this type of energy on body tissues, the aim of present study was to assess the possible effects of electromagnetic field (EMF) on undifferentiated tissues.Materials and Methods: The undifferentiated tissues obtained from 10-day fetal mesenchymal cells of mouse were divided into two groups, each included 10. The tissues were exposed to the EMF (50 Hz, 80 G) for 8 hours. After a 24 hour incubation, the samples were fixed, processed, sectioned (5 µm thickness) and stained with hematoxiline and eosin method. Then, they were studied using light microscopy. Results: Our findings indicated that while the undifferentiated tissues were converted to cartilage in the EMF exposed group they left unchanged in the control group.Conclusion: The EMF may induce the differentiation of tissues in undifferentiated cells.
