Figure 4. CCK-8 assay. Normal group indicates that neurons were incubated in the same buffer containing glucose at 37°C in a regular CO₂ (5%) incubator. OGD/R had a detrimental effect on the survival of neurons, and this effect could be diminished by the addition of osteocalcin (*, P<0.05; **, P<0.01).
