This invention discloses a method for rejuvenating senescent cells based on osmotic pressure induction. Senescent cells typically exhibit cell volume expansion. This method constructs a hypertonic environment by introducing a biocompatible polymeric solute (such as 2% or 0.5% PEG 300), applying controlled hypertonic pressure to senescent cells to induce cytoplasmic dehydration and counteract volume expansion. Experiments have demonstrated that long-term hypertonic compression intervention (such as 7 days of 0.5% PEG treatment) can effectively reset the mechanical state of senescent cells. After removing the pressure and restoring isotonic culture, some senescent cells can regain their proliferative capacity, as evidenced by negative SA-β-gal staining, strong positivity for Ki67 and EdU proliferation markers, and long-term stable passage. This invention provides a non-genetic, physical means to achieve cell rejuvenation, offering a new pathway for the intervention of age-related diseases.
