Construction Strategy and Progress of Whole Intervertebral Disc Tissue Engineering

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Orthopedics

Background:

• Degenerative disc disease (DDD) is a primary cause of low back pain, leading to significant healthcare utilization.
• Current treatments for DDD primarily manage symptoms rather than regenerating damaged intervertebral discs, limiting long-term efficacy.

Purpose of the Study:

• To review current literature on tissue engineering strategies for intervertebral disc regeneration.
• To summarize advancements in seed cells, scaffold materials, and construction methods for tissue-engineered intervertebral discs.
• To identify challenges and future directions in the field.

Main Methods:

• Comprehensive review of published research on intervertebral disc tissue engineering.
• Analysis of data on cell sources, biomaterials, and whole disc construction techniques.
• Evaluation of animal studies and the influence of mechanical factors.

Main Results:

• Significant progress has been made in developing tissue-engineered intervertebral discs.
• Key areas of investigation include seed cell selection, scaffold material properties, and biomechanical considerations.
• No ideal regenerative strategy for DDD has been fully established yet.

Conclusions:

• Tissue engineering presents a promising regenerative strategy for DDD, moving beyond symptomatic treatment.
• Continued research into seed cells, scaffolds, and mechanical loading is crucial for developing effective treatments.
• Intervertebral disc tissue engineering holds the potential for revolutionary advancements in managing DDD.
