Harmony in chaos: understanding cancer through the lenses of developmental biology.

Abstract

When we think about cancer, the link to development might not immediately spring to mind. Yet, many foundational concepts in cancer biology trace their roots back to developmental processes. Several defining traits of cancer were indeed initially observed and studied within developing embryos. As our comprehension of embryonic mechanisms deepens, it not only illuminates how and why cancer cells hijack these processes but also spearheads the emergence of innovative technologies for modeling and comprehending tumor biology. Among these technologies are stem cell-based models, made feasible through our grasp of fundamental mechanisms related to embryonic development. The intersection between cancer and stem cell research is evolving into a tangible synergy that extends beyond the concepts of cancer stem cells and cell-of-origin, offering novel tools to unravel the mechanisms of cancer initiation and progression.
