Figure 8

Glioma grades represented as a plot of cell density for the different cell populations. Simulations of each grade of glioma represented as a plot of cell density for the different cell population (normoxic, hypoxic and necrotic) with respect to the distance from the center of the tumor. Green curve: normoxic cells, blue curve: hypoxic cells, red curve: necrotic cells. (a), (c) and (e): proposed model produced by different diffusion-proliferation pairs, (b), (d) and (f): comparable results of [3].
