该方案的目标是将动态对比增强磁共振成像 (DCE-MRI) 应用于小鼠的原位胰腺肿瘤异种移植物。DCE-MRI 是一种分析目标组织中微血管系统的非侵入性方法,可用于评估新疗法后肿瘤的血管反应。
该程序的总体目标是将动态对比增强磁共振成像或 D-C-E-M-R-I 应用于小鼠的原位胰腺肿瘤异种移植物。这是通过首先从腹部取出胰腺,然后将人胰腺癌细胞缓慢注入胰尾来实现的。然后胰腺返回腹部,当肿瘤直径为 5 到 7 毫米时,将塑料板和表面线圈放置在组织块 humas 的顶部。
最终,肿瘤异种移植物的微血管可以通过 D-C-E-M-R-I 可视化。与皮下肿瘤异种移植物的 D-C-M-R-I 等传统方法相比,该技术的主要优点是原位胰腺肿瘤模型允许评估原发性肿瘤微环境,包括新生血管形成血液供应和肿瘤细胞侵袭。该程序将由我们实验室的研究助理 Sharon Samuel 和研究技术员 Marie Warren 进行演示。
