The effect of down‐regulation of miR‐15a/15b on apoptosis of mesenchymal stem cells under oxygen and glucose deprivation (OGD) condition. A and B, The expression levels of miR‐15a and miR‐15b from Control, OGD 12 hours, OGD 12 hours+miR‐15a/15b inhibitors, and OGD 12 hours+miR‐15a/15b mimics were detected by quantitative reverse transcription–polymerase chain reaction. Data are expressed as median (quartile 1–quartile 3), n=3. **P<0.01 vs Control; ##
P<0.01 vs OGD 12 hour group; &
P<0.05, &&
P<0.01 vs OGD 12 hour group. C‐F, The expression levels of vascular endothelial growth factor receptor 2 (VEGFR2) (C and D) and Bcl‐2 (E and F) from Control, OGD 12 hours, OGD 12 hours+miR‐15a/15b inhibitors, and OGD 12 hours+miR‐15a/15b mimics were detected by Western blotting assay. Data are expressed as median (quartile 1–quartile 3), n=3. **P<0.01 vs Control; ##
