Epithelial progenitor cells with mutant p53, but not wild-type p53, were immortalized, and telomerase was upregulated, by exposure to resveratrol.

Resveratrol dose dependently prevented the onset of endothelial progenitor cells (EPCs) senescence and increased their proliferation and migration. Resveratrol significantly increased telomerase activity in these cells.
