Tendon tissue engineering: progress, challenges, and translation to the clinic.

Area of Science:

• Musculoskeletal tissue engineering
• Biomaterials science
• Regenerative medicine

Background:

• Significant advancements in tissue engineered constructs (TECs) for tendon repair.
• Challenges persist in translating TECs into clinically effective and commercially viable products.
• Understanding normal tendon development and adult healing is crucial for improving engineered tendon repair.

Purpose of the Study:

• To review key issues in engineering tendon repairs.
• To outline strategies for developing clinically successful tendon tissue engineering products.
• To bridge the gap between laboratory research and clinical application.

Main Methods:

• Literature review of current tissue engineering strategies for tendon repair.
• Analysis of challenges in preclinical models and commercialization.
• Synthesis of insights from developmental biology and adult healing processes.

Main Results:

• Current TECs show promise but require more clinically relevant models, including degenerative tendons.
• Translation to larger animal models is necessary to assess clinical implications.
• Commercialization hurdles, stemming from patient uniqueness, need strategic solutions.

Conclusions:

• Advancing validation models for TECs is essential to gain surgeon confidence.
• Addressing both scientific and commercialization challenges is vital for successful tendon tissue engineering.
• A comprehensive approach integrating developmental insights and improved models will drive clinical success.
