Abstract

This chapter discusses Mina Bissell's pathbreaking research on cancer. Along with her colleagues and students, Bissell focused her attention on how the causal pathways regulating cell behavior were a two way street. Healthy cells’ and cancer cells’ behavior are both highly context-dependent. The pathway to this insight was not direct. Bissell’s work began with research into cellular metabolism. As a result of this early research, she found that cells can “change their fate” – revert to, or activate, functions not typical of cells in the differentiated state. This had important implications for our understanding of cancer's etiology and treatment. Bissell - among others - emphasized in her research that it was not simply cell intrinsic properties – such as mutations to “oncogenes” and “tumor suppressor” genes – that determine the typical behaviors of cancer cells, but also a variety of extrinsic properties in the surrounding environment: metabolic and other signaling molecules, the extracellular matrix, and tissue architecture.
