Summary
Intervertebral disc degeneration (IVDD) treatment requires overcoming the harsh disc environment. Future therapies must combine advanced cell sources with biomaterials and bioengineering for successful disc regeneration.
Area of Science:
- Regenerative Medicine
- Biomedical Engineering
- Orthopedics
Background:
- Low back pain is a global health issue, with intervertebral disc degeneration (IVDD) as a primary cause.
- Current cell-based therapies for IVDD show limited success due to the hostile disc microenvironment.
- Factors like hypoxia, acidity, and inflammation in degenerative discs impede cell function and survival.
Purpose of the Study:
- To review recent advances in cell-based therapies for IVDD, focusing on overcoming microenvironmental challenges.
- To critically evaluate different cell sources and emerging strategies for enhancing regenerative efficacy.
- To identify key components for successful clinical translation of IVDD treatments.
Main Methods:
- Comprehensive literature review of PubMed, Web of Science, and Google Scholar (2020-2026).
- Critical evaluation of studies on cell sources, repair mechanisms, biomaterials, and microenvironment strategies.
- Analysis of translational studies and emerging technologies for IVDD regeneration.
Main Results:
- Successful IVDD regeneration requires addressing both cell source and the degenerative niche.
- Mesenchymal stromal cells, nucleus pulposus cells, and iPSC-derived cells have distinct regenerative potentials.
- Biomaterials, EVs, genetic engineering, and preconditioning enhance cell survival and repair.
Conclusions:
- Integrated strategies combining optimized cell sources, biomaterials, and microenvironment modulation are crucial for IVDD regeneration.
- Precision bioengineering and smart delivery platforms are key to improving therapeutic outcomes.
- Advancing these approaches will enable durable repair and effective clinical treatments for degenerative disc disease.

01:27Degenerative Disc Disease I: Introduction
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...
01:23Degenerative Disc Disease ll: Pathophysiology
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
01:21Stem Cell Therapy for Tissue Regeneration
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.
