[Bioluminescent imaging to monitor tumor progression and metastasis in live animal].

Abstract

Animal models allowing more sensitive and early detection of tumorigenesis and metastasis are instrumental in the fight for developing effective therapies against aggressive forms of cancer. In the present chapter, the advantages and limitations of the bioluminescent imaging (BLI) approach are discussed. Although BLI provides rapid, highly sensitive, noninvasive and quantitative detection of small tumors and micrometastases, several issues like the low anatomic resolution or the attenuation of the luminescent signal with tissue depth must be considered when using this technology.
