Summary
Spinal pathology, common in aging, causes disability and pain, often from degenerative disc disease. Regenerative cellular therapies offer promising alternatives to surgery for treating this condition.
Area of Science:
- Biomedical science
- Regenerative medicine
- Orthopedics
Context:
- Spinal pathology significantly impacts quality of life and leads to disability.
- Prevalence increases with age, presenting diverse symptoms.
- Low back pain, often due to degenerative disc disease (DDD), is a common syndrome.
Purpose:
- To analyze principles of regenerative cellular therapy and cell replacement therapy for DDD.
- To compare various cell types used in cellular therapy for DDD.
Summary:
- Degenerative disc disease (DDD) involves irreversible intervertebral disc alterations.
- Current surgical treatments for DDD are symptomatic.
- Regenerative medicine offers potential alternative therapeutic strategies.
Impact:
- Highlights the need for novel treatments for DDD.
- Provides a comparative overview of cell types for regenerative therapy.
- Informs future research in spinal regenerative medicine.

Degenerative 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...
Degenerative 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...
Herniated 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...
