Three-dimensional in vivo imaging of tumors expressing red fluorescent proteins

3D imaging of genetically-engineered fluorescent tumors enables quantitative monitoring of tumor growth/regression, metastatic processes, including during anticancer therapy in real-time.Fluorescent tumor models for 3D imaging require stable expression of genetically encoded fluorescent proteins and maintenance of the properties of tumor cell line including growth rate, morphology, and immunophenotype.In this chapter, the protocol for 3D imaging of tumors expressing red fluorescent protein are described in detail.
