In embryonic development, formation of blood vessels in the retina of the eye is critically dependent on prior establishment of a mesh of astrocytes. Astrocytes emerge from the optic nerve head and then migrate over the retinal surface in a radially symmetric manner and mature through differentiation. We develop a PDE model describing the migration and differentiation of astrocytes and study the appropriateness of the model equation components that combines approximate Bayesian computation (ABC) and sensitivity analysis (SA). Comparing numerical simulations to experimental data, we identify model components that can be removed via model reduction using ABC+SA.
