Supplementary Material

Supplementary Figure 1 compares the nuclei size and proliferation rate of HUVEC cultures at passage 3 and 10. Supplementary Figure 2 compares the phenotype and the behavior of human fibroblasts at early and late passages. Supplementary Figure 3 describes the gene expression analysis (for the P16 and P21 mRNAs) performed in human fibroblasts at early and late passages. Supplementary Figure 4 shows the proliferation analysis using Ki67 as a marker for proliferation. Supplementary Figure 5 shows the effect of a chronic vitamin E supplementation in human fibroblasts during the progression of cellular senescence.
