The genes involved in cartilage degradation in the pathogenesis of osteoarthritis ( OA) are the Nuclear Factor Kappa Beta (NFĸβ) gene, which plays a vital role in modulating cartilage damage involving activation of pro-inflammatory cytokines, including prostaglandin E2 (PGE2). This pure experimental research aimed at analyzing the relationship between the expression of NFĸβ genes after administration of mesenchymal stem cells in osteoarthritis synoviocytes in vitro from Wharton's Jelly (WJ-MSCs). The samples were isolated from synovial tissues of patients with osteoarthritis who underwent Total Knee Replacement (TKR) surgery and then divided into six treatment groups, each with four replicates. Groups I and II were the synoviocyte-control classes of 24h and 48h (synoviocytes, incubated for 24 and 48 hours respectively). Groups III and IV were control groups of 24h and 48h WJ-MSCs (mesenchymal stem cells derived from the Wharton's Jelly, incubated for 24 and 48 hours respectively). Finally, Groups V and VI were the 24-hour and 48-hour co-cultural treatment groups (synoviocyte co-culture and WJ-MSCs, Incubated, for 24 and 48 hours respectively). Using qPCR, PGE2 gene and NF NFκβ gene expressions were observed in each population. Tests showed 0.61 and 0.61, respectively, after the administration of WJ-MSCs, the expressions of the NFκβ-p65 and PGE2 genes in the 24h classes. In the 48h group, meanwhile, both numbers fell to 0.15 and 0.47, respectively. These indicate a strong correlation between the NFκβ-p65 gene and PGE2 gene expressions in OA synovial cells after the administration of MSC-WJ (r = 0.903).
