Relative ratio of ACAN (A), COL2A1 (B), and SOX9 (C) gene expression in mesenchymal stem cells (MSCs) cultured in chondrogenic differentiation medium without (control) or with 0.1 or 1.0 μg/ml Link N for 7, 14, and 21 days. The results are shown as mean ± SD of three independent experiments with MSCs from three different donors. *P < 0.05 versus control.
