Development of a novel bone-adapting injectable smart hydrogel for bone tissue engineering

Defects that weaken bone tissue are a major challenge in orthopedic surgery as they can lead to fractures, significant morbidity, and reduced quality of life. Existing treatments do not provide the necessary mechanical strength, adaptability to dynamic bone remodeling, and osteoinductive properties required for effective bone regeneration. The BONEGEL project addresses this gap by proposing an injectable, self-healing hydrogel specifically designed to treat bone defects in non-weight-bearing bone. The BONEGEL approach includes several key innovations: a dextran-based hydrogel that utilizes the host-guest interactions of cyclodextrins to create a dynamic hydrogel that can adapt to irregular bone defects; the incorporation of laponite, a nanosilicate that improves the mechanical strength and osteoinductive properties of the hydrogel; and an effective and safe release of dexamethasone to accelerate bone regeneration. In addition, the project will optimize an ex vivo model for testing injectable materials for bone tissue engineering to ensure the efficacy and safety of the hydrogel prior to clinical application. This interdisciplinary project brings together expertise in materials science, tissue engineering and regenerative medicine to provide a safer and more efficient alternative to current treatments for bone defects and expedite its clinical application. By overcoming the limitations of existing therapies, BONEGEL has the potential to improve patient outcomes and shorten recovery times. This aligns with the EU's priorities for innovation and sustainability in healthcare, ultimately promoting a healthier population and better quality of life for patients. Beyond the scientific, societal and economic impact, this project will advance my career by providing me with the critical knowledge and experience I need to position myself as a leader in the biomaterials and tissue engineering fields and open doors to future academic collaborations and industry partnerships.
