Abstract:

Ionizing radiation is widely used in X-ray imaging, radiotherapy and nuclear power, which would cause serious damage to normal tissue. Although some drugs can be used for the treatment of the injury, the effect is not satisfactory. Mesenchymal stem cells (MSC) have the ability to migrate to position of disease to promote the repair of damaged tissues, and have great applicational prospects in the treatment of many different types of ionizing radiation injuries. Mesenchymal stem cell exosomes have similar functions to MSC, such as repairing tissue damage, suppressing inflammatory responses and regulating the immune system. Therefore, they can be used to treat ionizing radiation injury instead of MSC. In this paper, the latest research progress on the biological effects of ionizing radiation, the biological functions and the repair of ionizing radiation damage of MSC and exosomes are reviewed.

Key words: Ionizing radiation, Mesenchymal stem cells, Exosome
