Publication protocol

The senescent cells were detected with senescence β-galactosidase staining kit (Cell Signaling, Beverly, MA, USA) according to manufacturer’s protocol. The growth media was removed and the cells were once rinsed with PBS. Next, a fixative solution containing 2% formaldehyde and 0.2% glutaraldehyde was added to the cells. Then, again the cells were rinsed with PBS two times and incubated with a staining solution containing 5-bromo-4-chloro-3-indolyl-D-galactopyranoside, citric acid/sodium phosphate (pH 6.0), 1.5 M NaCl, 20 mM MgCl2, potassium ferrocyanide and potassium ferricyanide. After 11 to 14 hr, light microscopy was applied to identify the senescent cells which can be visualized as blue cells. Thirty fields were randomly selected to calculate the percentage of SA-β-gal cells.
