Figure 2From: TGF-β1 induces senescence of bone marrow mesenchymal stem cells via increase of mitochondrial ROS productionDose–response of β-galactosidase activity in bone marrow mesenchymal stem cells (bmMSCs) after exposure to 0, 1, 5 and 10 ng/ mL recombinant mouse transforming growth factor β1 ( TGF-β1) for 24 hours. Bar graphs represent mean ± SD (4 independent experiments/group). *P < 0.05 vs. control.Back to article page
