Tumors are complex bio-systems and cell growth is coupled to the chemical modifications of the extracellular microenvironment. Tumor cells and their
microenvironment, therefore, constitute an evolving cellular ecosystem and a detailed understanding of the underlying dynamics might provide insights into tumor development and resistance to therapy. Here we present a real-life computer program for the simulation of multicell tumor spheroids. Simulation results compare quite well with experimental data and yields unique view of tumor microenvironment.
