The Effects of Naproxen on Chondrogenesis of Human Mesenchymal Stem Cells

Abstract: Currently, there are no established treatments to prevent, stop, or even retard the degeneration of articular cartilage in osteoarthritis (OA). Biological repair of the degenerating articular cartilage would be preferable to surgery. There is no benign site where autologous chondrocytes can be harvested and used as a cell source for cartilage repair, leaving mesenchymal stem cells (MSCs) as an attractive option. However, MSCs from OA patients have been shown to constitutively express collagen type X (COL-X), a… Show more

“…We showed that naproxen can regulate chondrogenic differentiation in normal human MSCs by suppressing the gene expression of Indian hedgehog and parathyroid hormone/parathyroid hormone-related protein (PTH/PTHrP) signaling pathways in a time-dependent manner, suggesting a complex interaction of different signaling pathways 78 , but NSAIDs had a concentrationdependent effect on the differentiation and growth of MSCs, accelerated differentiation and growth at low concentrations, and negatively affected differentiation at high concentrations 79 . NSAIDs may inhibit bone formation via blockage of MSC chondrogenic differentiation, an important intermediate phase in normal endochondral bone formation 80 .…”

“…This gene increases bone resorption by stimulating osteoclastic formation, 28 meaning that a downregulated IL11 could promote osteogenesis. Specific genes for ossification, namely COL10A1 and TIMP3 , 29 were downregulated in Winter vs. Control. TIMP3 decreased in the category Winter vs. Summer.…”

“…The results are in line with our findings as presented in Figure 1. Overall, mixed results are found in the literature on the effect of naproxen on chondrogenic marker expression (COL2A1, SOX9, ACAN, and GAG content) and this might be influenced by the cell model, chondrogenic differentiation induction, time of exposure to naproxen and concentration used in these studies 25,26 . In this study, ATDC5 cells were used, which is a (murine) cell model described to resemble the chondrogenic phase of endochondral ossification 13 .…”

“…PTHrP shares the same receptor as PTH and is also described to influence the chondrogenic differentiation of MSCs 40 . Interestingly, for naproxen it was already described that its effects on hypertrophic differentiation during osteogenic and chondrogenic differentiation of MSCs could be explained via deregulation of the Ihh/PTHrP signaling 25,26 . Amano et al, 41 showed that Ihh regulates expression of Col10a1 directly via binding of the Gli1/2 transcription factors on the Col10a1 promoter, but also indirectly via induction of Runx2 and subsequent transcriptional complex formation of Gli1/2, Runx2, and Smads which are able to induce Col10a1 expression.…”
