Tissue engineering strategies for treating intervertebral disc degeneration.

Area of Science:

• Regenerative Medicine
• Biomaterials Science
• Orthopedic Surgery

Background:

• Low back pain (LBP) is a prevalent clinical issue, largely driven by intervertebral disc degeneration (IDD).
• IDD involves reduced nucleus pulposus cells and extracellular matrix imbalance within the intervertebral disc (IVD).
• Pathological features of IDD include inflammatory responses and stress stimulation.

Purpose of the Study:

• To systematically review the relationship between LBP and IDD.
• To describe healthy IVD physiology and IDD pathology.
• To evaluate tissue engineering strategies for IVD repair.

Main Methods:

• Literature review focusing on preclinical and clinical studies of IVD tissue engineering.
• Analysis of seed cells, bio-scaffolds, and bioactive factors for IVD repair.
• Examination of current treatment methods and clinical trials for IDD.

Main Results:

• Tissue engineering research shows promise for IVD repair using various components.
• Preclinical and clinical findings highlight the potential of specific cell types, scaffolds, and growth factors.
• A comprehensive therapeutic approach integrating these elements is being explored.

Conclusions:

• Tissue engineering represents a significant research focus for addressing IDD and LBP.
• Further research is needed to overcome obstacles and optimize therapeutic strategies for IVD regeneration.
• Understanding the interplay of cells, scaffolds, and factors is crucial for successful IVD repair.
