Outline of Final Research Achievements

The present study demonstrated that chondrogenic differentiation of Mesenchymal stem cells (MSCs) was modulated by parathyroid hormone (PTH). The results revealed that PTH has opposite effects on chondrogenesis when administered at different concentrations. Namely, low to moderate concentrations of PTH promoted chondrogenic differentiation of MSCs, whereas chondrogenesis of MSCs was inhibited and not stimulated by a higher concentration of PTH. Based on clinical experience with the efficacy and safety of PTH for bone metabolism, PTH may also be useful clinically for cartilage repair.
