Fig. 3From: Effect of lentivirus-mediated growth and differentiation factor-5 transfection on differentiation of rabbit nucleus pulposus mesenchymal stem cellsFCM cell transfection rate. A GDF5 positive rate (%) in the normal group; B GDF5 positive rate (%) in the transfection group; C GDF5 positive rate (%) of the control group; D The GDF5 positive rate (%) of the transfection group was significantly higher than that of either the normal or control groups (P < 0.01)Back to article page
