Cellular senescence, a state of irreversible growth arrest, impairs primitive cell repair functions. This review explores its impact on tissue repair and proposes interventions to counteract senescence in regenerative medicine.
Area of Science:
- Cellular Biology
- Regenerative Medicine
- Tissue Repair Mechanisms
Background:
- Cellular senescence is a stress-induced state characterized by irreversible growth arrest.
- Senescence involves significant changes in gene expression, epigenetics, and secretome.
- These alterations negatively impact the reparative capacity of primitive cells.
Purpose of the Study:
- To review the multifaceted effects of cellular senescence on tissue repair processes.
- To identify and propose potential therapeutic interventions targeting senescence in regenerative medicine.
Main Methods:
- Literature review of studies on cellular senescence and tissue repair.
- Analysis of mechanisms by which senescence affects cellular function and tissue regeneration.
- Exploration of existing and novel strategies to modulate senescence.
Main Results:
- Cellular senescence contributes to impaired tissue repair by altering the cellular microenvironment and reducing regenerative potential.
- Specific senescent cell-associated secretory phenotypes (SASPs) play a critical role in modulating tissue repair.
- Interventions aimed at clearing senescent cells or mitigating their effects show promise.
Conclusions:
- Cellular senescence presents a significant barrier to effective tissue repair and regenerative medicine.
- Targeting cellular senescence offers a promising therapeutic avenue for enhancing tissue regeneration.
- Further research is needed to develop safe and effective senolytic or senomorphic strategies.
