Glycosaminoglycan (GAG) secretion into 1-ml culture medium over the 3-day period preceding medium collection when mesenchymal stem cells (MSCs) were cultured in chondrogenic differentiation medium in the absence (control) or presence of Link N. The results are shown as mean ± SD of three independent experiments with MSCs from three different donors. *P < 0.05 versus control.
