Summary
Polymeric biomaterials inspired by nature, particularly polyurethanes, show promise for tissue engineering. This review covers polyurethane scaffolds for regenerating soft and hard tissues.
Area of Science:
- Polymeric biomaterials
- Biomaterials engineering
- Tissue engineering
Background:
- Nature-inspired design is crucial for advanced polymeric biomaterials.
- Polyurethane (PU) implants are increasingly used in tissue engineering due to tunable properties.
- PU's chemical stability, biocompatibility, and low cytotoxicity make them suitable for biomedical applications.
Purpose of the Study:
- To critically review studies on polyurethane scaffolds for tissue regeneration.
- To highlight the potential of biomimetic polyurethanes in mimicking native tissue properties.
- To include non-isocyanate polyurethanes (NIPUs) in the review for soft and hard tissue regeneration.
Main Methods:
- Review of recent scientific literature on polyurethane scaffolds.
- Analysis of studies focusing on biomimetic properties (mechanical, morphological, surface).
- Inclusion of research on both conventional and non-isocyanate polyurethanes.
Main Results:
- Polyurethane building blocks can be modified to create biomimetic structures.
- Advances in manufacturing enable the creation of sophisticated biomimetic materials.
- Polyurethanes show significant potential for regenerating cardiac muscle, blood vessels, skeletal muscle, and bone tissue.
Conclusions:
- Polyurethane scaffolds offer a versatile platform for tissue engineering applications.
- Biomimetic design is key to achieving functional tissue regeneration with PUs.
- Further research into PUs, including NIPUs, is essential for advancing regenerative medicine.
