A free textbook on Economic Principles in Cell Biology

How can a cell maintain itself as a living being? Living cells, shaped by billions of years of evolution, have developed many ways to adapt to their environment, e.g. by regulation of gene expression. But the rules of physics and chemistry enforce certain boundaries on what cells can achieve and how they can allocate their own resources. Our goal is to uncover some of these governing principles. Shaped by evolution, cells "do certain things right", and computational models of cells often assume that this "doing something right" can be described by evoking optimality principles.

In our open textbook - to which anyone can contribute - we intend to give an overview of established approaches to "cellular economics", from descriptions of simple metabolic systems to cell growth, variability, and dynamic behaviour. For more information about our book project, please see our website for (actual and potential) authors and this poster.
