Cell cultures
MurineMC3T3-E1 cells were purchased from the Center Laboratory
for Tissue Engineering, College of Stomatology, Fourth Military Medical
University, Xi'an, China [29,30]. The cellswere cultured in α-MEMusing
10% heat-inactivated FBS and 100 U/ml penicillin and 100 mg/ml streptomycin
in a condition of 5% CO2 and 37 °C. H2O2 acted as exogenous
ROS treatment, whereas N-acetyl-L-cysteine (NAC) acted as an ROS
cleaner. When the cells reached confluence, the serum-free medium
containing Rb2 was dissolved in distilled water and cultured for 24 h before
the administration of 0.3 mM H2O2 for 24 h. For each experiment,
Rb2 administration continued after the pretreatment. All of the experiments
were performed in duplicate wells and repeated three times.
