Percentage of SA-β Gal positive cells in HFF strains ± Gy irradiation. Young HFF strains (PD20) were subjected to no and 20 Gy of gamma irradiation (0, 20 Gy) and the percentage of SA-β gal positive cells were measured at different time points after irradiation treatment. Between 80 and 100 cells were analyzed for each data point. The bars indicate the mean ±S.D. Values statistically different from their controls (0 Gy irradiation) are indicated with an asterix (t-test): *p < 0.05, ***p < 0.001. n = 3 in all cases
