The effect of FSP diffusion. (A) The activation time of tumor invasion for three values of FSP diffusion coefficient (D_s). (B) The ECM degradation area: the area was estimated by calculating the area of the region where the ECM level is below a threshold $\left(\rho <{\rho }^{\text{th}}=0.8\right)$. (C) TAP activity: the activity was estimated by the area of region where the TAP level is above the threshold $P_t>P_t^{\text{th}}=2.0$ (. (D) The FSP level: the average value of FSP levels was estimated in the localized invasion region [48,52] × [56,58]
