Roughness and dynamics of proliferating cell fronts as a probe of cell–cell interactions

Abstract Juxtacellular interactions play an essential but still not fully understood role in both normal tissue development and tumour invasion. Using proliferating cell fronts as a model system, we explore the effects of cell–cell interactions on the geometry and dynamics of these one-dimensional b...
