Abstract
Nowadays the world is full of some less known species of signals which connect us together. So human beings are continually exposed to electric, magnetic and electromagnetic fields. In order to investigate the effects of magnetic fields on cell survival, bone marrow mesenchymal stem cells were exposed to 15 mT static magnetic field in the presence and the absence of 0.5 gray X-ray. The rate of dead cells didn't show a significant difference when the cells were treated with static magnetic field alone. But after an acute exposure with the ionizing radiation, the field increased the percentage of survived cells significantly and rescued a part of X-ray induced apoptotic cells. These data show that static magnetic field treatment, suppresses apoptosis and promotes survival in bone marrow stem cells of rat. Thus, magnetic fields might act as a co-mutagenic and co-carcinogenic agent with increasing the risk of tumor development by inhibiting apoptosis.
