Percentage of SA-β gal positive cells in MRC-5 fibroblasts ±Gy irradiation. Young MRC-5 strains (PD34) were subjected to different doses of Gamma irradiation (0, 2, 15, 20 Gy) and the percentage of SA-β Gal positive cells were determined at different time points after irradiation treatment. Between 80 and 100 cells were analyzed for each data point. The bars indicate the mean ±SD. Values statistically different from their controls (0 Gy irradiation) are indicated with an asterix (t-test): *p < 0.05, **p < 0.01, ***p < 0.001. n = 3 in all cases
