摘要:

背景:目前放疗治疗脑胶质瘤效果不理想,可能因素有很多。
目的:探讨脑胶质瘤中肿瘤干细胞的体外放射敏感性。
方法:取脑胶质瘤细胞,接种于含生长因子的无血清培养基中培养,取细胞活力最强的位点扩增3-5代的肿瘤球细胞,给予不同X射线剂量照射,检测其细胞活力,以确定最适的放疗剂量。
结果与结论:胶质瘤中不同部位的肿瘤细胞增殖活力有差异;8 Gy以上X射线剂量对脑肿瘤干细胞具有显著的杀伤作用。说明脑胶质瘤具有异质性,部位不同,脑肿瘤干细胞增殖活力不同;不同的放疗剂量对脑肿瘤干细胞有不同的影响。

Abstract:

BACKGROUND: Radiotherapy effect on of brain glioma is not ideal, and there are various possible factors that influence the therapeutic effect.
OBJECTIVE: To investigate the in vitro radiosensitivity of brain cancer stem cells in brain glioma.
METHODS: Glioma cells were isolated and seeded into the serum-free medium containing growth factors for culture. Glioma cells from the most active cell site were subcultured to 3-5 generations. Glioma cell vitality was assessed to determine the optimal dose of X-ray radiation.
RESULTS AND CONCLUSION: Distinct difference in activities of proliferation could be found among cancer stem cells from different sites of glioma. X-ray dosages above 8 Gy had notable killing effect on brain cancer stem cells. Different irradiation dosage had different influence on cancer stem cells.
