Pioglitazone Protects Compression-Mediated Apoptosis in Nucleus Pulposus Mesenchymal Stem Cells by Suppressing Oxidative Stress

Figure 2

Effects of pioglitazone on NP-MSCs viability and proliferation. (a) The CCK-8 assay was used to evaluate the cell viability with various concentrations of pioglitazone (0, 10, 20, 50, and 100 μM) on NP-MSCs. (b) The CCK-8 assay was used to evaluate the effect of pioglitazone on compression-mediated NP-MSCs viability. Con served as a control group. Data are presented as the of three independent experiments. versus the control group; # versus the compression group. (c) Representative micrographs of EdU staining by fluorescence microscopy. The red fluorescence indicates EdU-positive cells (200x).
