Association between miR-146a-5p expression and the protein levels of CXCR4 and Col II. Chondrocytes were separately transfected with miR-146a-5p mimics, miR-146a-5p inhibitors and NC for 48 h using Lipofectamine® 3000. Following stimulation with 100 ng/ml SDF-1 for 2 days, cells were harvested to evaluate the protein levels of CXCR4 and Col II. (A) Represent western blot showing the protein levels of CXCR4 and Col II. (B and C) Summary data from 3 independent western blot analysis experiments on the protein levels of (B) CXCR4 and (C) Col II. **P<0.01 and ***P<0.001 vs. the corresponding control group. miRNA, miRNA; Col II, type II collagen; CXCR4, C-X-C chemokine receptor type 4; SDF-1, stromal cell-derived factor 1; NC, negative control.
