Summary
This application note demonstrates how LunaX™ ECM, tuned to a physiologically relevant stiffness of 1.5 kPa, supports the development of stable capillary-like networks in HUVEC–pericyte co-cultures. Over seven days, LunaX ECM produced more organised and interconnected vascular structures than Matrigel under the tested conditions.
What you’ll learn
- How to establish a 3D HUVEC–pericyte co-culture model for studying angiogenesis.
- Why physiologically relevant matrix stiffness is important for endothelial network formation.
- How vascular networks develop in LunaX ECM over a seven-day culture period.
- How LunaX ECM and Matrigel compared using CD31, actin and DAPI confocal imaging.
- How this model can support anti-angiogenic drug screening, vascularised tissue research and extracellular-vesicle analysis.
Key findings
- LunaX ECM supported early endothelial network formation by Day 3, followed by progressive branching and increased interconnectivity.
- By Day 7, co-cultures in LunaX ECM formed well-branched, interconnected capillary-like networks with organised cytoskeletal architecture.
- Matrigel cultures produced comparatively sparse and irregular structures, with inconsistent branching across the seven-day experiment.
- The 1.5 kPa LunaX matrix provided a mechanically defined environment within the physiological stiffness range of capillary-associated tissue.
- LunaX ECM’s defined, growth-factor-free composition provides a reproducible baseline for mechanistic angiogenesis studies and drug-response testing.
