    Area of Science:

    • Biomaterials Science
    • Regenerative Medicine
    • Orthopedics

    Background:

    • Intervertebral disc (IVD) degeneration is a leading cause of low-back pain (LBP), affecting over 80% of the population and imposing a significant socio-economic burden.
    • Current clinical solutions for IVD repair and regeneration remain limited, highlighting the need for innovative therapeutic strategies.

    Purpose of the Study:

    • To review advances in decellularised extracellular matrix (ECM)-based scaffolds for intervertebral disc (IVD) regeneration.
    • To discuss the optimization of decellularization methods, sterilization, recellularization techniques, and biocompatibility testing for IVD tissue engineering.
    • To address the impact of donor profiles and explore clinical perspectives and challenges for decellularised ECM biomaterials in treating disc degeneration and LBP.

    Main Methods:

    • Review of current literature on decellularisation techniques (physical, chemical, enzymatic) for IVD tissue.
    • Analysis of recellularisation strategies using various cell types and assessment of biocompatibility.
    • Evaluation of sterilization procedures and donor selection criteria for therapeutic efficacy.

    Main Results:

    • Optimized decellularisation methods yield cell-free IVD scaffolds that retain native ECM structure, composition, and mechanical properties.
    • Successful recellularisation strategies and biocompatibility tests are crucial for driving effective IVD regeneration.
    • Donor profile significantly influences the therapeutic success of decellularised ECM-based treatments.

    Conclusions:

    • Tissue-engineering strategies utilizing decellularised IVD ECM represent a promising advancement for treating disc degeneration and associated low-back pain.
    • Further research and development are needed to overcome hurdles for the clinical translation of these biomaterials.
    • Decellularised IVD scaffolds offer a potential path towards halting or reversing the degenerative cascade and improving patient quality of life.
