Abstract
Most of preclinical cancer studies use xenograft models established from human cell lines or patient-derived cancer cells subcutaneously implanted into the flank of immunocompromised mice. These models are often assumed to represent the original diseases and are valuable tools, at least to some extent, for understanding both the basic biology of cancer and for proof-of-concept studies of molecularly targeted therapies. However, analyzing the cellular behavior of individual components within xenografts, including tumor cells, stromal cells, immune cells, and blood vessels, is challenging. In particular, it has been difficult and urgently required to trace the whole process of heterogeneous tumor microenvironment formation mediated by various components described above. Here we demonstrate a method for monitoring this process using a window device system that we have recently developed and a subcutaneous xenograft model that accurately recapitulates the histology of human lung adenocarcinoma. Use of our imaging window device and a multiphoton laser scanning microscope provides a powerful tool for investigating tumor heterogeneity and responses to drug treatments in an in vivo live imaging system.
