Fig. 3From: Effects of dynamic radial tensile stress on fibrocartilage differentiation of bone marrow mesenchymal stem cellsWestern blot protein analysis. The bands represent protein expression for each group (a). The amount of Col I significantly increased at 5% tensile strength, and the signal for α-SMA obviously increased at 10%. The synthesis of Col II gradually decreased and was significantly reduced at 10% (b). *P < 0.05Back to article page
