Cell Form and Function: Interpreting and Controlling the Shape of Adherent Cells

Abstract

Beautiful images of animal cells cultured on surfaces are ubiquitous in biological research, but these shapes also carry valuable information about the cells and the organism that they came from. Cell morphology is an emergent property of the cellular phenotype as well as of the physiological and signaling state of the cell. Many functional changes in cells cause stereotypical changes in cellular morphology, and some changes in shape can also cause characteristic changes in cellular phenotype. Thus, controlling cell shape through substrate engineering may emerge as another mechanism to modulate cell function for human health. This review summarizes current understanding of the morphology-phenotype connection, and surveys progress in the effort to interpret and control cell morphology.
