使用荧光和生物发光的体内光学成像在时空分辨率和特异性方面上级其他方法,并且代表了以侵入性较小的方式全面研究活生物体的新技术。如今,它是研究癌症生物学许多方面(包括动态侵袭和转移)不可或缺的技术。在活体中的荧光或生物发光信号的观察中,由诸如吸收和散射的光学特性引起各种问题,因此,难以观察深部组织。最近在活体动物深层组织观察技术方面的发展克服了这一困难,改进了生物发光蛋白、荧光蛋白和荧光染料,以及双光子激发显微镜等检测技术。本文介绍了生物发光和荧光成像的技术发展及其在体内的应用,并对体内光学成像技术在癌症研究中的应用前景进行了展望。
In vivo optical imaging using fluorescence and bioluminescence is superior to other methods in terms of spatiotemporal resolution and specificity, and represents a new technology for comprehensively studying living organisms in a less invasive way. Nowadays, it is an indispensable technology for studying many aspects of cancer biology, including dynamic invasion and metastasis. In observations of fluorescence or bioluminescence signals in a living body, various problems were caused by optical characteristics such as absorption and scattering and, therefore, observation of deep tissue was difficult. Recent developments in techniques for observation of the deep tissues of living animals overcame this difficulty by improving bioluminescent proteins, fluorescent proteins, and fluorescent dyes, as well as detection technologies such as two‐photon excitation microscopy. In the present review, we introduce these technological developments and in vivo application of bioluminescence and fluorescence imaging, and discuss future perspectives on the use of in vivo optical imaging technology in cancer research.
