    Area of Science:

    • Biomaterials Science
    • Tissue Engineering
    • Cell Biology

    Background:

    • Human extracellular matrix (ECM) complexity presents challenges in reverse engineering.
    • Fibroblast-secreted ECM is a promising acellular biomaterial source.
    • Standard culture conditions impart aberrant mechanical cues affecting ECM deposition.

    Approach:

    • Engineered microtissues from primary human fibroblasts in low-adhesion microwells.
    • Optimized culture and decellularization protocols for producing human ECM.
    • Investigated cardiac and lung fibroblasts from healthy and diseased donors.

    Key Points:

    • Characterized gene expression, protein composition, microstructure, and mechanical properties of the decellularized ECM.
    • Demonstrated successful ECM production from both cardiac and lung fibroblasts.
    • Highlighted the ability to capture tissue- and disease-specific ECM characteristics.

    Conclusions:

    • Developed a method for biomanufacturing patient- and tissue-specific ECM.
    • Potential applications include organoid drug screening and implantable scaffolds.
    • This approach enables the generation of personalized ECM for regenerative medicine.
