title: The biology of boundary conditions: cellular reconstitution in one, two, and three dimensions.
abstract: Reconstituting cellular behavior outside the complex environment of the cell allows the study of biological processes in simplified and controlled settings. Making the leap from cells to test tubes, however, carries the inevitable risk of removing too much context and therefore sacrificing the important biochemical, mechanical, or geometrical constraints that guide the system's behavior. In response to this challenge, reconstitution experiments have recently begun to focus not only on including the right molecules but also on faithfully recapitulating the constraints that are present within a cell. By setting the appropriate biological boundary conditions, these experiments are uncovering how dimensional constraints within the cellular environment guide biological processes.
