放射性损伤在接受放射治疗的癌症患者中很常见。在这种情况下,辐射引起的损伤可能是难治的,因为受损组织或器官的再生反应没有得到很好的刺激。间充质干细胞已成为管理辐射引起的损伤的理想候选者。此外,越来越多的证据表明,来源于间充质干细胞的外泌体对修复组织损伤具有类似的作用,主要是因为这些外泌体携带各种生物活性物质,如miRNA、蛋白质和脂质,这些物质可以影响免疫调节、血管生成以及细胞存活和增殖。虽然间充质干细胞衍生的外泌体修复辐射损伤的机制尚未完全阐明,但我们打算将其生物学特征转化为辐射损伤模型,旨在为辐射损伤的管理提供新的见解。
Radiation-induced damage is a common occurrence in cancer patients who undergo radiotherapy. In this setting, radiation-induced damage can be refractory because the regeneration responses of injured tissues or organs are not well stimulated. Mesenchymal stem cells have become ideal candidates for managing radiation-induced damage. Moreover, accumulating evidence suggests that exosomes derived from mesenchymal stem cells have a similar effect on repairing tissue damage mainly because these exosomes carry various bioactive substances, such as miRNAs, proteins and lipids, which can affect immunomodulation, angiogenesis, and cell survival and proliferation. Although the mechanisms by which mesenchymal stem cell-derived exosomes repair radiation damage have not been fully elucidated, we intend to translate their biological features into a radiation damage model and aim to provide new insight into the management of radiation damage.
