Tumor microenvironment models: ex vivo, in vitro and in silico approaches to address targeted therapies

Abstract

"Cancer is the second leading cause of mortality worldwide, despite the extraordinary advances in the last two decades due to the development of targeted therapies. These target particular molecules required for cell growth and tumorigenesis; nonetheless, de novo or acquired resistance to therapy often lead to patient relapse and disease progression. There is cumulating evidence supporting the importance of tumor microenvironment (TME)-driven mechanisms in cancer progression and drug resistance. Therefore, there is a need for cancer models in which critical components of the TME, such as the non-malignant cell types and the extracellular matrix (ECM), are represented and tissue architecture is maintained.
