To examine senescence-associated β-galactosidase (SA β-gal activity), cultured cells were stained using a senescence cell histochemical staining kit (Merck KGaA) according to the manufacturer instructions. Briefly, overconfluent cultures on day 14 were subcultured in 60-mm culture dishes. The cell aggregates after SA β-gal staining were examined using a Biorevo BZ-9000 microscope (Keyence).
