Extracellular matrix matters: matrix-based bioscaffolds in advancing translational cancer research and targeted therapy

The onset, development, and progression of cancer are greatly influenced by the microenvironmental cues originating from diverse elements within the tumor niche. Extracellular matrix (ECM), the complex and dynamic macromolecular three-dimensional network (3-D), governs cell functionality and plays key roles in tumor growth and spreading. This article highlights the significance of ECM-based bioscaffolds in providing a relevant microenvironment not only for studying tumor behavior and drug efficacy but also for narrowing the gap between translational cancer research and targeted cancer treatment. The development of novel and user-friendly platforms that resemble the human tumor microenvironment in early and advanced cancer stages, may help to predict treatment response, thus facilitating the development and testing of new drugs, bridging the gap between in vitro and in vivo models. In addition, we present innovative strategies leveraging ECM bioscaffolds for personalized cancer treatment, including drug delivery systems and tissue engineering approaches. Specific case studies as well as ethical concerns related to the use of ECM bioscaffolds in research and therapy are also presented and critically discussed. By elucidating the intricate interplay between ECM and cancer biology, this article underscores the potential of ECM bioscaffolds as novel platforms for shaping future therapeutic interventions and advancing precision oncology.
