项目摘要

Summary It is widely held that energy creation and use strategies employed by tumors may provide important diagnostic and therapeutic opportunities. However, tools to directly and microscopically visualize these strategies do not yet exist because most of the metabolites cannot be labeled for microscopy. This project uses recently developed a coherent Raman imaging method that can rapidly obtain molecular vibration signatures of these unlabeled metabolites, potentially making them visible. If the project is successful, it will yeild a microscope that will allow cancer researchers and clinicians to, for the ﬁrst time, visualize metabolic activity in intact tumors, on a cell-by-cell basis, and should facilitate discovery of new therapies and diagnostics. Developing such an instrument presents signiﬁcant challenges. The project will approach these in our ﬁrst Aim by developing a detailed theoretical model of our imaging approach, and testing it against a simpliﬁed and well-controlled series of experimental tissue mimics. This dual model approach will allow us to discover the most effective path to realizing the necessary instrument sensitivity and reliability. In the second Aim we test the microscope in actual tissues and cell culture that is independently analyzed for content of metabolites measure by BCARS.

概括人们普遍认为，肿瘤所采用的能量产生和使用策略可以提供重要的诊断然而，目前还没有直接和微观可视化这些策略的工具。存在是因为大多数代谢物无法进行显微镜标记，该项目使用最近开发的。一种相干拉曼成像方法，可以快速获得这些未标记的分子振动特征如果该项目成功，它将产生一个可以让它们可见的显微镜。癌症研究人员首次将完整肿瘤中的代谢活动逐个细胞地可视化基础，并应促进新疗法和诊断的发现。开发这样的仪器提出了重大挑战，该项目将首先解决这些问题。目标是开发我们的成像方法的详细理论模型，并根据简化的和这种双重模型方法将使我们能够发现一系列良好控制的实验组织模拟。实现必要的仪器灵敏度和可靠性的最有效途径在第二个目标中，我们测试了。实际组织和细胞培养物中的显微镜，独立分析代谢物的含量由 BCARS 提供。
