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

Figure 4

Effects of pioglitazone on NP-MSCs apoptosis. (a) Flow cytometric analysis was used to detect cell apoptosis by annexin V/PI staining. (b) Quantitative analysis of the apoptotic NP-MSCs rate. (c) The TUNEL staining was used to investigate apoptotic changes under a fluorescence microscope (100x). (d) Quantitative analysis of TUNEL-positive cells. Data are presented as the of three independent experiments. versus the control group; # versus the compression group.
