Figure 8. BMSCs treated with different concentrations of t-BHP and stained with SA-β-gal (×100). The concentration of t-BHP used to treat BMSCs is 100 μmol/L (A), 200 μmol/L (B), 300 μmol/L (C), 400 μmol/L (D), and 500 μmol/L (E), and 600 μmol/L (F). The aging macaque BMSC model was established by inducing cells with 200 μmol/L t-BHP for 6 h.
