Interactions at scaffold interfaces: Effect of surface chemistry, structural attributes and bioaffinity

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Tissue Engineering

Background:

• Effective regenerative medicine depends on the interaction between biomaterial implants and cells.
• Scaffolds are crucial for tissue regeneration, providing sites for cell adhesion, growth, and differentiation.
• Current scaffold fabrication often overlooks crucial interfacial interactions, leading to rejection and treatment failure.

Purpose of the Study:

• To review the role of biointerfaces in regenerative medicine.
• To highlight the importance of scaffold interfacial properties for successful tissue engineering.
• To emphasize the need for understanding microenvironmental interactions for improved clinical applications.

Main Methods:

• Review of existing literature on biomaterial-scaffold-cell interactions.
• Focus on surface chemistry, pore structure, and hydro-affinity of scaffolds.
• Analysis of biointeractions at the scaffold-tissue interface.

Main Results:

• Scaffold interfacial properties significantly influence cellular affinity and tissue regeneration.
• Lack of understanding of interfacial microenvironments leads to poor cell survival and intervention failure.
• Bespoke biocompatibility, optimal pore structure, and cell attachment cues are essential for scaffold success.

Conclusions:

• Understanding scaffold biointerfaces is critical for advancing tissue engineering.
• Tailoring biomaterial properties to specific microenvironments enhances regenerative therapy outcomes.
• Further research into scaffold interfacial properties will drive clinical translation of regenerative medicine.
