The Billion Cell Construct: Will Three-Dimensional Printing Get Us There?

Abstract

How structure relates to function-across spatial scales, from the single molecule to the whole organism-is a central theme in biology. Bioengineers, however, wrestle with the converse question: will function follow form? That is, we struggle to approximate the architecture of living tissues experimentally, hoping that the structure we create will lead to the function we desire. A new means to explore the relationship between form and function in living tissue has arrived with three-dimensional printing, but the technology is not without limitations. © 2014 Jordan S.
