en 32695280 <p>Background: Osteoarthritis (OA) is a chronic disease that attacks joints and bones which can be caused by trauma or other joint diseases. Stem cell and Conditioned Medium (CM) of stem cells are developed for OA therapy, which is minimally invasive. It can decrease inflammation and be a replacement for knee surgery.&nbsp; This study aimed to utilize human Wharton&rsquo;s Jelly-Mesenchymal Stem Cells (hWJMSCs) as an alternative OA therapy.</p> <p>Methods: CM from hWJMSCs induced by IGF1 was collected. The OA cells model (IL1&beta;-CHON002) culture was treated as follows: 1) with hWJMSCs-CM 15% (v/v); 2) with hWJMSCs-CM&nbsp; 30% (v/v); 3) with IGF1-hWJMSCs (IGF1-hWJMSCs-CM) 15% (v/v); 4) with IGF1-hWJMSCs-CM 30% (v/v). Parameters including inflammatory cytokines (IL10 and TNF&alpha;), extracellular matrix degradation (MMP3 expression), and chondrogenic marker (<em>COL2</em> expression) were determined.</p> <p>Results: The most significant increase in <em>COL2</em> chondrogenic markers was found in IL1&beta;-CHON002 treatment using 15% CM of hWJMSCs induced with IGF1. CM of hWJMSCs can reduce inflammatory cytokines (TNF&alpha; and IL10) and matrix degradation mediator MMP3. Better result was gained from IGF1-induced hWJMSCs-CM.</p> <p>Conclusion: CM of IGF1-hWJMSCs reduce inflammation while repairing injured joint in the human chondrocyte OA model.</p> Chondrocyte, IGF1, Osteoarthritis, Proinflammatory, Wharton’s jelly 172 178 https://www.ajmb.org/En/Article.aspx?id=30429 https://www.ajmb.org/PDF/En/FullText/30429.pdf HannaSari Widya KusumaBiomolecular and Biomedical Research Center, Aretha Medika, Utama, Bandung,, West Java, Indonesia41600WahyuWidowati41601RimontaFebby GunanegaraFaculty of Medicine, Maranatha Christian University, Bandung, West Java, Indonesia41602BerryJuliandiDepartment of Biology, Faculty of Mathematics and Natural Sciences, Bogor Agricultural University, IPB Darmaga Campus, Bogor, West Java, Indonesia41603NyomanEhrich ListerUniversitas Prima Indonesia, Medan North Sumatera, Indonesia41604SeilaArumwardanaBiomolecular and Biomedical Research Center, Aretha Medika, Utama, Bandung, West Java, Indonesia41605DewaniTediana YusepanyBiomolecular and Biomedical Research Center, Aretha Medika, Utama, Bandung, West Java, Indonesia41606DwiSurya ArtieBiomolecular and Biomedical Research Center, Aretha Medika, Utama, Bandung, West Java, Indonesia41607EndenDea Nataya Biomolecular and Biomedical Research Center, Aretha Medika, Utama, Bandung, West Java, Indonesia41608KamilaYashfa GunawanBiomolecular and Biomedical Research Center, Aretha Medika, Utama, Bandung, West Java, Indonesia41609IkaAdhani SholihahBiomolecular and Biomedical Research Center, Aretha Medika, Utama, Bandung, West Java, Indonesia41610ErmiGirsangUniversitas Prima Indonesia, Medan North Sumatera, Indonesia41611ChrismisNovalinda GintingUniversitas Prima Indonesia, Medan North Sumatera, Indonesia41612IndraBachtiarStem Cell and Cancer Institute, Jakarta, Indonesia41613HarryMurtiStem Cell and Cancer Institute, Jakarta, Indonesia41614
