In our last article, we compared 2D organ-on-a-chip devices and 3D organoids with respect to their use in drug discovery, highlighting their importance in modeling diseases and evaluating efficacy and safety during drug discovery and development . We also presented the major catch-22 challenge in disease modeling; disease biology is complex and developing a ‘good’ disease model requires a deep understanding of disease mechanisms and pathogenesis, both of which come through gathering Real-World Evidence and modeling the disease. In this article, we take a closer look at some of the most important considerations for choosing an approach to model disease, focusing specifically on 2D...
