Engineering Intervertebral Disc Regeneration: Biomaterials, Cell Sources and Animal Models

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Orthopedics

Background:

• Intervertebral disc (IVD) degeneration is a common cause of chronic spinal issues like low back pain and herniation.
• Current surgical treatments, such as IVD removal and spinal fusion, can lead to adjacent segment degeneration due to biomechanical disruption.
• The loss of IVD function significantly impacts spinal biomechanics.

Purpose of the Study:

• To review current tissue engineering strategies for IVD regeneration.
• To highlight the use of biomaterials, animal models, and cell sources in IVD repair.
• To discuss future directions and opportunities in the field of IVD regeneration.

Main Methods:

• Review of existing literature on IVD tissue engineering.
• Analysis of biomaterials, cell sources, and animal models employed in IVD regeneration research.
• Discussion of challenges and future prospects in the field.

Main Results:

• Tissue engineering, particularly using bioscaffolds and stem cells, shows significant promise for IVD regeneration.
• Various biomaterials, cell types, and animal models are being investigated for their efficacy.
• Significant progress has been made in developing bioengineering approaches for IVD repair.

Conclusions:

• Tissue engineering represents a promising avenue for regenerating the intervertebral disc.
• Further research into biomaterials, cell sources, and optimized models is crucial for clinical translation.
• Addressing the limitations of current surgical interventions through regenerative approaches is a key future opportunity.
