Fig 7. Properties of a glioma formed by the appearance of an over proliferating cell.

(a) Normal (blue circles) and glioma (red circles) cell densities versus the distance to the center of space, for the glioma of Fig 6. Eight graphs corresponding to eight time points are represented from t = 0 (appearance of the first glioma cell, dark red and blue graphs), to t = 336 days (very light red and blue graphs), with a time interval of 42 days. (b) Temporal evolution of the mean radius of the glioma of Fig 6. (c) Temporal evolution of the total cell density, when an over proliferating cell appears at time t = 0. (d) Normal (blue lines) and tumoral (red lines) proliferating (plain curve) and disappearing (dashed curve) cell densities, in a 1 mm³ cube, where an over proliferating cell appears at time t = 0.
