Review: epigenetic clock resetting and senescence strategies in intervertebral disc degeneration
This review describes how epigenetic dysregulation and senescent disc cells drive intervertebral disc degeneration, and evaluates proposed clock-reversal strategies plus a proposed 'clear, prime, then seed' roadmap. [1]
Automatic summary · not editorially reviewed
The key findings
The review states that current clinical treatments for disc degeneration are only palliative and cannot reverse programmed cellular senescence driven by epigenetic dysregulation. [1]
The review synthesizes how heterogeneous senescent cell populations and their secretory phenotype orchestrate a destructive vicious cycle in disc degeneration. [1]
The authors propose a synergistic "clear, prime, then seed" roadmap that sequentially combines the evaluated interventions for optimal regeneration. [1]

Senescent cells and the disc microenvironment
The review states that intervertebral disc degeneration is the leading pathological cause of low back pain and that current clinical treatments are only palliative and cannot reverse programmed cellular senescence driven by epigenetic dysregulation. This process is characterized by progressive loss of nucleus pulposus cell identity and a self-amplifying senescence-associated microenvironment. The authors synthesize how heterogeneous senescent cell populations and their secretory phenotype (SASP) orchestrate a destructive vicious cycle in disc degeneration.

Epigenetic aging clock and proposed reversal strategies
The review dissects the synergistic interplay among DNA methylation, histone modifications and non-coding RNAs that constitutes the "epigenetic aging clock" and drives premature cellular aging within the disc. It evaluates emerging therapeutic strategies aimed at clock reversal: senolytic clearance of senescent cells, epigenetic remodeling using small-molecule inhibitors or CRISPR-dCas9 editing, and cellular reprogramming approaches ranging from iPSC differentiation to direct lineage conversion.

Proposed roadmap and theoretical framework
The authors propose a synergistic "clear, prime, then seed" roadmap that sequentially combines these interventions for optimal regeneration. They describe the work as providing a systematic theoretical framework for the clinical translation of epigenetic-targeted therapy for disc degeneration and as breaking through the cognitive limitation of traditional mechanical wear theory. These are proposals and a framework, not validated treatments.
