Abstract | INTRODUCTION: Intervertebral disc degeneration is associated with low back
pain. Mesenchymal stem cells (MSCs) have been used to halt
the progression or regenerate the disc with hopes to prevent
or treat discogenic back pain. However, the safety and efficacy
of the use of MSCs for such treatment in animal and human
models at short- and long-term assessment (i.e., greater than
48 weeks) have not been systematically addressed. Therefore,
the aim of this study was to perform a systematic review of
comparative controlled studies addressing the use of MSCs to
that of no treatment/saline for the treatment of disc
degeneration.
MATERIALS AND METHODS:
Online databases PubMed, PubMed Central, EMBASE, BIOSIS,
and MEDLINE were searched. Controlled trials in animal
models and humans were eligible for inclusion. Trial design,
MSC characteristics, injection method, disc assessment, outcome
intervals, and complication events were assessed. Validity
of each study was assessed by appropriateness of
randomization, blindness of outcome assessment, and sample
size. Two individuals independently searched the literature,
extracted data parameters, and assessed validity.
RESULTS:
Twenty-four animal studies were included but no controlled
studies in humanswere identified. All three types of MSCs (i.e.,
bone marrow, synovial, and adipose tissue) showed successful
tissue inhibition of disc degeneration. Bone marrow-derived
MSC showed superior quality of disc repair that was marked
with restoration of extracellular matrix in the disc when itwas
compared with other treatments, including TGF-β1, nucleus
pulposus bilaminar coculture, and axial distraction regimen.
However, osteophyte development was reported in two studies
as a potential complication of MSC transplantation. Overall,
the incidence of MSC-related complications was < 0.5%. Metaanalyses
indicated that MSC increased disc space height in the
majority of animal models. Results

CONCLUSIONS:
Based on the first systematic reviewaddressing the safety and
efficacy of the use of MSCs for disc degeneration prevention/
regeneration, the current evidence, based on animal models,
suggests that in the short-term MSC transplantation is safe
and effective in halting disc degeneration; however, additional
and larger studies are needed to assess the long-term
regenerative effects and potential complications. Inconsistency
in methodological design and outcome parameters prevent
any robust conclusions. In addition, randomized controlled
trials in humans are needed to assess the safety and efficacy of
such therapy. |
