Figure 2

Effect of PSP on D-galactose-induced myocardial aging in mice. (a) Representative images of β-galactosidase staining and p21 immunohistochemistry in the myocardium, and the β-galactosidase staining-positive cells were indicated by arrows (magnification, ×400 for β-galactosidase staining and ×200 for p21 IHC). (b, c) The protein expressions of p21 and p53 in the myocardium. Data are ; . vs. Con; # and ## vs. D-gal.
