Background:

Chronic low back pain (CLBP) affects a significant portion of adults, leading to disability and economic burden.
Identifying the structural source of CLBP is crucial for effective treatment, with intervertebral discs common in younger adults and facet/sacroiliac joints in older adults.
Current treatments for painful discs and joints are limited, representing an unmet clinical need for restorative interventions.

Purpose of the Study:

To explore cellular supplementation as a treatment strategy for CLBP originating from structural damage.
To review the potential of exogenous cells in promoting extracellular matrix production and alleviating pain and disability.
To highlight the progression from animal studies to human trials for diskogenic CLBP.

Main Methods:

Review of contemporary literature on CLBP sources and treatment strategies.
Analysis of the pathophysiology of annular injury and its impact on disc restoration.
Examination of cellular supplementation as a therapeutic approach, including data from animal studies.

Main Results:

Annular injury can lead to a catabolic state in intervertebral discs, impairing self-repair and causing cell loss.
Cellular supplementation shows promise in preclinical studies for enhancing repair and reducing pain in diskogenic CLBP.
Human trials regulated by the Food and Drug Administration are underway, primarily focusing on diskogenic CLBP.

Conclusions:

Cellular supplementation is a viable strategy for addressing CLBP by initiating repair in injured lumbosacral structures.
Further research is needed to address questions regarding cell viability and nutrient support in vivo.
While promising for diskogenic CLBP, research on cellular therapies for facet and sacroiliac joint pain is less developed.
