Ageing Biology: Cellular Senescence & SASP Biomarkers
“Quantifying the variance between chronological and biological age”
Assessing cellular senescence, metabolic stress, and low-grade inflammation associated with biological ageing. Biological ageing is characterized by the progressive accumulation of senescent cells, mitochondrial inefficiency, and chronic sterile inflammation (inflammaging). Reficio's 4-tier ageing biology panel benchmarks cellular health via SASP cytokines (IL-6, TNF-α), mitochondrial regulator FGF-21, vascular inflammation indices (hs-CRP), and metabolic cofactors.

Ageing Biology & Cellular Senescence Overview
Assessing cellular wear, metabolic stress, and inflammaging hallmarks
Clinical Mechanisms & Biological Insights
- Senescent cells resist apoptosis and secrete toxic SASP factors into neighboring tissues.
- Inflammaging accelerates vascular stiffness and neurodegenerative decline.
