This chapter presents a stepwise optimization of a Matrigel®-based in vitro angiogenesis assay using human umbilical vein endothelial cells (HUVECs) to achieve reproducible and quantifiable tube formation. Critical parameters-including culture surface, matrix composition and thickness, coating temperature and incubation time, growth factor-defined serum-free medium, and cell seeding density-were systematically evaluated. Optimal conditions were identified as 3 mg/mL Matrigel (100 μL/well), polymerized at 22 °C for 90 min, with HUVECs seeded at 20,000 cells/cm2 and cultured in a defined growth factor cocktail. Standardized imaging and ImageJ-based analysis enabled robust quantification of network features. This protocol improves consistency, stability, and comparability across angiogenesis studies.
