Following publication of the original article [1], due to mistakes, the flow chart of miR-21 overexpression, miR-21 inhibitor and miR-21 mimic NC in Fig. 3, and the corresponding histogram need to be replaced. The senescent behavior of miR-21 mimic and miR-21 inhibitor in Fig. 4 will be replaced, accompanying the relative histogram.
Fig. 3.
Effect of miR-21-5p on OA chondrocytes (a). CCK-8 assay was to quantify viable cells (b). the cells were subjected to FACS analysis to determine the cell apoptosis rate. *P < 0.05 compared with the normal group. #P < 0.05 compared with the OA group
Fig. 4.
To identify senescent cells, chondrocytes were stained with SA β-gal, and observed under a light microscope (magnification × 100). Values represent the mean ± SD from three independent replicate experiments.*P < 0.05 compared with the normal group. #P < 0.05 compared with the OA group
