We propose high order positivity preserving schemes to approximate the marginal tip density by combining an asymptotic reduction with weighted essentially non oscillatory and strong stability preserving time discretization. We capture soliton-like solutions representing blood vessel formation and spread towards hypoxic regions.engjournal article2191-0294https://doi.org/10.1515/ijnsns-2021-0112https://www.degruyter.com/document/doi/10.1515/ijnsns-2021-0112/htmlopen accessAngiogenesisAsymptotic reductionFokker–PlanckHigh order schemesKinetic modelsPositivity preservingAnálisis numéricoBiomatemáticas1206 Análisis Numérico
