The Use of Collagen-Based Materials in Bone Tissue Engineering

Area of Science:

• Biomaterials Science
• Orthopedic Research
• Tissue Engineering

Background:

• Synthetic bone substitute materials (BSMs) are increasingly replacing autologous grafting in bone tissue engineering (BTE).
• Collagen type I, a primary bone matrix component, is crucial for developing ideal synthetic BSMs.
• Despite advancements in collagen research and material preparation, challenges like poor mechanical properties and fast degradation hinder clinical translation.

Purpose of the Study:

• To review the latest applications of collagen-based materials in bone regeneration.
• To highlight the potential of collagen-based biomimetic BSMs in BTE.
• To identify future development directions for collagen-based materials in BTE over the next decade.

Main Methods:

• Literature review of approved collagen-based bone substitute materials on the market.
• Analysis of current research trends in collagen-based biomimetic BSMs.
• Synthesis of information on collagen types, preparation techniques, and modification technologies.

Main Results:

• Collagen-based materials are central to developing synthetic BSMs for BTE.
• Current collagen-based materials face limitations in mechanical strength, degradation rate, and osteoconductive activity.
• Combinations with inorganic materials and bioactive substances are explored to enhance BSM performance.

Conclusions:

• Collagen-based materials are vital for bone regeneration, but require further optimization for clinical application.
• Future research should focus on overcoming current limitations to improve the efficacy of collagen-based BSMs in BTE.
• The review provides insights into the evolving landscape and future potential of collagen in bone tissue engineering.
