Radiation therapy is one of the most effective and indispensable treatment modalities for cancer patients. Known tissue complications caused by radiation-induced stem cell depletion, may result in structural and functional alterations of the surrounding matrix. Although, studies have demonstrated that ionizing radiation can induce apoptosis and senescence, little is known about the effects of therapeutic irradiation concerning the commitment of mesenchymal stem cells to the os...

Astronauts on exploratory space missions will experience a complex environment that includes microgravity and radiation. While the deleterious effects of unloading on bone are well established, fewer studies have focused on the effects of radiation. Space radiation produces distinct biological damages which, up to now, little is known about the correlation between radiation exposure and bone tissue. In our study we used osteoblastic precursor cells to investigate the radiation...
