Abstract: BACKGROUND: The role of cellular senescence in tissue repair has received increasing attention. The accumulation of senescent cells not only affects normal physiological functions but may also exacerbate inflammation and fibrosis, thereby accelerating the aging process. In recent years, the potential therapeutic value of clearing senescent cells in tissue repair has become a research hotspot.
OBJECTIVE: To discuss the dual role of cellular senescence in tissue repair and explore the potential application of senescent cell clearance strategies in delaying the aging process and promoting tissue repair.
METHODS: The authors conducted a search in the PubMed database using the keywords “Senolytics, aging, senescence, treatment, clearance, tissue injury” for literature published prior to May 2025. Relevant articles were initially selected by screening the titles and abstracts to exclude those with irrelevant content, outdated viewpoints, or repetitive studies. A total of 137 relevant articles were finally selected for in-depth analysis through a combination of careful and broad reading.
RESULTS AND CONCLUSION: Cellular senescence is one of the key markers of aging. Senescent cells secrete senescence-associated secretory phenotype factors that contribute to local tissue repair and regeneration. The clearance of senescent cells can alleviate chronic inflammation, promote tissue function restoration, and delay the onset of age-related diseases. Current strategies for senescent cell clearance include both non-targeted and targeted approaches. The former delays aging through lifestyle changes, while the latter selectively eliminates senescent cells using drugs, transgenic techniques, gene editing, reprogramming technologies, and immunotherapies, thereby slowing the aging process.
