Figure 5. The contour plot of average radial growth velocities 〈v〉 over 10 trials with with respect to the interactions between two invasive cells β_ii and between two proliferative cells α_pp.

If α_pp is fixed in the range of nearly α_pp < 0.9, v decreases with increasing β_ii but increases again with further increases, and vice visa for β_ii < 0.3. Other parameters are in Table S1. See text for additional detail.
