Figure 5. Sensitivity analysis of chemotactic signal strength.

Figure 5

Sensitivity of morphometric parameters to relative strength of bound (Inline graphic) and soluble (Inline graphic) VEGF. Red points (lacunae) and blue points (nodes) show averages of measured quantities in simulations (n = 3), half-transparent regions represent standard deviations. Insets show portions of networks (200×200Inline graphic) where the relative signalling strength (Inline graphic) is set to soluble-VEGF-only (Inline graphic, left), bound-VEGF-only (Inline graphic, right) and equal strengths (Inline graphic, center). Arrowhead indicates the reference value.
