Correction
After publication of our recent article [1], it was brought to our attention that an inaccurate observation was made in the Results section. We stated that different concentrations of SF have no effect on normal chondrocytes viability. However, Figure 1 demonstrates that SF concentrations 500 and 1000 μmol/L significantly increase chondrocytes viability compared with the control group. The following sentence has now been deleted from the Results section: "All of these results show that different concentrations of SF from 125 to 1,000 μmol/l have no effect on normal chondrocyte viability".
