Extracellular Matrix-derived Foam Fabrication via Lyophilization: A Procedure to Generate Biological Scaffolds from ECM of Decellularized Tissues

Executive Industry Relevance

ECM-derived foams provide a biologically relevant 3D scaffold system that supports physiologically meaningful cell culture and tissue regeneration studies. By leveraging native extracellular matrix components without chemical crosslinking, this method enhances target validation and mechanistic de-risking in preclinical model development. The approach enables reproducible, scalable production of disease-relevant systems for lead identification and assay development in regenerative medicine pipelines.
