Progress of Gene-Functionalized Regenerative Material Repair Intervertebral Disc Degeneration

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Gene Therapy

Background:

• Intervertebral disc degeneration (IDD) is a major cause of chronic low back pain.
• Existing treatments for IDD face challenges, including genetic susceptibility and limitations of traditional gene therapy and regenerative materials.
• Current regenerative materials improve the local environment but do not address the root cause of IDD.

Purpose of the Study:

• To provide an overview of intervertebral disc physiology, pathology, and genetic factors in IDD.
• To discuss current treatment options for IDD and their limitations.
• To propose gene-functionalized regenerative materials (GRM) as a significant advancement for IDD treatment.

Main Methods:

• Constructing GRM by incorporating genes (pDNA, siRNA, mRNA, miRNA) into regenerative materials via physical embedding or chemical bonding.
• Reviewing the physiological and pathological features of intervertebral discs (IVD).
• Analyzing genetic susceptibility to IDD and existing therapeutic strategies.

Main Results:

• GRM enhances the safety and controllability of gene therapy for IDD.
• GRM effectively repairs IDD by addressing the disease progression at its root.
• GRM overcomes the limitations of simple regenerative materials in reversing IDD.

Conclusions:

• GRM represents a promising therapeutic strategy for intervertebral disc degeneration.
• This approach combines the benefits of regenerative materials and gene therapy for enhanced IDD treatment.
• Future research should focus on the challenges and development of GRM-based therapies for IDD.
