Development and Optimization of Resorbable Biomaterials and Advanced 3D Scaffold Fabrication Techniques for Tissue...

Tissue engineering has advanced significantly, driven by innovations in resorbable biomaterials and 3D scaffolds that serve as critical frameworks for tissue regeneration. This review highlights the integration of natural and synthetic polymers into scaffold design, emphasizing their capacity to mimic the extracellular matrix (ECM) and support cell adhesion, proliferation, and differentiation. The incorporation of advanced fabrication techniques such as 3D printing, nanotechnology, and electrospinning has enhanced scaffold functionality and precision, enabling the creation of patient-specific constructs. Significant challenges include balancing scaffold degradation rates with mechanical strength, managing immune responses, and optimizing biofabrication methods for clinical translation. Emerging materials, including bioactive polymers, nanogels, and graphene-based scaffolds, along with advancements in biofabrication such as 4D printing, demonstrate significant potential for addressing these limitations. This review emphasizes the importance of interdisciplinary collaboration, regulatory adaptation, and continuous research to transform scaffold technologies from experimental models into practical applications. This progress is crucial for improving clinical outcomes in regenerative medicine and for addressing complex tissue engineering challenges.
