Two Dimensional Modeling and Fractal Characterization of Tumor Vascular Network

Tumor networks display percolation like scaling, representing the first evidence for a biological growth process whose key determinants are local substrate properties. In this paper we present a full characterization of a recently proposed model which reproduces the main features of the biological system, focusing on its dynamical properties, on the fractal properties of patterns, and on the percolative phase transition. We propose a simple model which reproduces many features of the biological system.
