Development of an on-a-chip tumor microenvironment model
-
Context: In cancer research, a widely used model to study tumor growth and anti-tumor drugs/ therapies is the human tumor xenograft model. It consists in transplanting human cancer cells in immunodeficient mice. However, the tumor takes days to months to develop, when the graft does not fail. Moreover, although costly small animal imaging techniques can be used, this model is limited in the information that can be obtained regarding the interactions between the tumor and its environment. From another hand, the need for animal model alternatives is constantly increasing and is supported by the guiding principles known as the 3Rs (Replacement, Reduction, Refinement). Bio-MEMS that include engineered-tissues are one promising alternative.
Objectives & Methods: This project aims to develop a new in vitro tumor model that include the tumor microenvironment. The new model combines our previous vasculature-on-a-chip model (Fig.1) with cancer spheroids, which mimic tumors at a micrometer-scale (Fig.2). To get closer of in vivo conditions, the vasculature shall connect to a perfusion system in order to undergo shear stress.
Results:This new model will allow us to study tumor-driven angiogenesis [1] as well as the interactions between the cancer cells and the tumor microenvironment. It will also provide a tool for testing and developing candidate anticancer drugs.
