Figure 7
No difference of senescence-associated β-Gal activity and telomere length in ASC derived from different age groups. Representative pictures (A) and the quantitative measurement (B) of senescence-associated (SA) β-Gal staining in ASC derived from three age groups (n = 5 each) at two different passages are showed. *P < 0.05. (C) Relative lengths of telomere, as expressed as telomere/single-copy-gene (T/S) ratios, are showed (n = 10 each in 30-39 y and 40-49 y groups, n = 7 in 50-60 y group).
