Figure 1.

Effects of MP and MP supplemented with VK₂ on the proliferation and survival of BMSCs. (A, B) Cell viability staining was performed 144 h after incubation with MP and MP plus 10^-6 M VK₂, in which all living cells were stained blue and dead cells were stained green. (C) After treatment of MP and MP supplemented with different concentrations of VK₂, the proliferation of BMSCs was detected by CCK-8, and the results were expressed as the mean absorbance value (%) ±SD. (D). Images of BMSCs under light microscope at 144 h after cell adherence (*, significant difference versus the MP group, P < 0.05).
