a–c Representative micrographs of senescence-associated β-galactosidase (SA-β-gal)-positive cells (senescent cells) in EPCs derived from beagles at baseline, 48 h and 6 weeks after DHMC treatment, respectively, are shown. d The number of blue cells was counted manually from a total of 200 cells. Data are mean ± SD. *p < 0.05 versus baseline, ^#p < 0.05 versus 48 h
