Proposed three-part framework for senescent cells
The review describes cellular senescence as long considered irreversible, but says partial reprogramming work shows senescent cells stay in a metastable state that can be reset. It outlines a systemic framework for anti-aging interventions across three dimensions: raising nicotinamide adenine dinucleotide (NAD) levels for energy and coenzyme support; spatiotemporally controlled epigenetic resetting via Oct4-Sox2-Klf4-c-Myc (OSKM) factors or small molecules to restore youthful transcriptional programs without losing cellular identity; and restoring proteostasis through the autophagy-lysosome and ubiquitin-proteasome systems to clear damaged material and fold new proteins.

Open challenges named for safe reprogramming
Despite these advances, the review states the field still faces major challenges: no clearly defined therapeutic window for safe reprogramming, limited efficiency of tissue-specific delivery, and insufficient evidence on the long-term safety of therapeutic interventions. These are described as gaps, not resolved results.

Future directions: single-cell omics, methylation clocks, delivery platforms
Future studies, the review suggests, should integrate single-cell omics, DNA methylation clocks and artificial intelligence-assisted analyses to build precision metrics for evaluating cellular rejuvenation. It also calls for next-generation delivery platforms such as lipid nanoparticles (LNPs) and engineered exosomes to enable precision regulation of multi-level synergistic interventions. The review frames anti-aging medicine as moving from single-pathway interventions toward systemic reprogramming driven by synergy of metabolism, epigenetics and proteostasis.
