Abstract (original English)

The field of tissue engineering has witnessed significant advancements with the advent of 3D printing technologies, especially in wound healing. Innovative 3D-printed scaffolds incorporating decellularized biomaterials offer a promising approach to enhance the regenerative process. Decellularized biomaterials, derived from natural tissues, retain the extracellular matrix (ECM) components crucial for cell adhesion, migration, and tissue regeneration. These biomaterials are processed to remove cellular material, minimizing immune rejection and ensuring biocompatibility. When combined with the precision of 3D printing, these scaffolds can be tailored to match the specific needs of different wound types, promoting effective tissue integration and accelerated healing. This approach provides a platform for the creation of personalized, patient-specific treatments, addressing the limitations of traditional wound care strategies. Furthermore, the ability to print scaffolds with complex structures allows for the optimization of mechanical properties and porosity, facilitating nutrient exchange and cellular infiltration. This paper explores the potential of 3D-printed decellularized biomaterial scaffolds in revolutionizing wound healing, emphasizing their role in improving regenerative outcomes and reducing the risks of complications.
