杆状病毒—腺相关病毒载体基因修饰骨髓间充质干细胞靶向喉咽癌放射性 131 I治疗研究
发布时间:2021-01-07 08:55
目的:喉咽癌是头颈部常见的恶性肿瘤,预后极差。基于干细胞移植的基因疗法有望改善治疗效果。本研究中,我们明确人骨髓间充质干细胞(BMSCs)是否具有潜在喉咽癌归巢能力,探索杆状病毒-腺相关病毒载体(BV-AAV)介导碘化钠同向转运体(NIS)基因修饰BMSCs靶向喉咽癌放射性131I治疗的应用价值。方法:1.构建含有Luc-P2A-eGFP或NIS序列,侧翼插入AAV来源的反向末端重复序列(ITR)的BV-AAV载体(Bac-CMV-Luc-P2A-eGFP-ITR和Bac-CMV-NIS-ITR)。2.从感染效率,细胞毒性,多基因的正确表达这三个方面评价了BV-AAV在BMSCs中的应用价值。3.体外通过Transwell迁移试验;体内通过生物发光成像(BLI)和微单光子发射计算机断层扫描成像技术(micro-SPET/CT)示踪BMSCs体内生物学分布和肿瘤趋化性。4.利用18F-FDG micro-PET/CT评估治疗后肿瘤糖代谢情况;从肿瘤体积变化和肿瘤组织中细胞增殖标志物表达来评估治疗后肿瘤增殖情况。结果:1.MOI=400,Bac-...
