The effects of ExoBMSC and ExoPTH on inflammatory cytokines in OA chondrocytes were detected by an inflammation array. A Gene-level exploratory analysis and heatmaps of differentially expressed genes in the ExoBMSC and ExoPTH groups; (M1–M4): ExoBMSC group; (M5–M8): ExoPTH group. B KEGG functional enrichment in KEGG pathways was analyzed. C Statistical results of the inflammation array. Data are presented as the mean ± SD, *p < 0.05 (ExoPTH versus ExoBMSC group). ExoBMSC, Exosomes derived from BMSCs; ExoPTH, exosomes derived from PTH-preconditioned BMSCs; BMSCs, bone marrow mesenchymal stem cells
