More precisely, our results show that cell colony borders growing under high-pressure conditions have geometrical and dynamical properties that are markedly different from those corresponding to growth under homeostatic, normal pressure conditions. These behaviours are characterized by means of the so-called dynamical exponents of each type of growth. These are shown to correspond to statistical properties of solutions of some stochastic partial differential equations that account for the evolution of the interface between the expanding colony and the surrounding medium.engjournal articlehttps//doi.org/10.1016/j.jtbi.2006.05.020http://www.sciencedirect.com/science/article/pii/S0022519306002177restricted access517.986.6Surface-diffusionInvasive growthSolid tumorsStressDynamicsModelInterfaceSpheroidsStabilityPatternsTumour growthFractal propertiesDynamic scalingCell coloniesAnálisis matemático1202 Análisis y Análisis Funcional
