Oxygen-based cell proliferation. (a) Initial stage: time = 0 h, (b) cells begin proliferation: time = 600 h, (c) death of cells in the hypoxic region: time = 870 h and (d) further cell proliferation and growing hypoxic region: time = 1000 h. In figures 7–10, the oxygen concentration is given by its dimensionless values, where C (dimensionless) = C (in mm Hg) multiplied by 0.00225.
