Objective To measure the inductive effect of kartogenin on matrix metalloproteinase-2 levels during the differentiation of human bone marrow mesenchymal stem cells (hMSCs) into chondrocytes in vitro. Methods In vitro cultured bone marrow hMSCs were grown to the logarithmic phase and then divided into three groups: control group (0 µM kartogenin), 1 µM kartogenin group and 10 µM kartogenin group. After 72 h of culture, cell proliferation and differentiation were observed microscopically. Matrix metalloproteinase-2 (MMP-2) in the cell supernatant and type II collagen levels in the cells were detected by enzyme linked immunosorbent assay and immunofluorescence staining, respectively. Results Kartogenin induced the proliferation and differentiation of hMSCs. With the increase of kartogenin concentration, the level of type II collagen was increased, while the level of MMP-2 decreased. Conclusion These findings indicate that kartogenin can induce hMSCs to differentiate into chondrocytes, and with the increase of kartogenin concentration, degeneration of the cartilage extracellular matrix may be inhibited.

This study analyzed the action of Bone marrow mesenchymal stem cells (BMSCs) transplantation on arthritis rat model. Arthritis rat model was established using bovine type II collagen and CFA. BMSCs phenotype was assessed by flow cytometry and pathological changes was analyzed by H&E staining along with analysis of joint severity by AI score, inflammation by ELISA as well as level of NPY, MMP-2, and MMP-9. The form of passaged BMSCs was spindle shaped with positive expression of CD29 and CD44. The structure of articular cavity in arthritis rats was disordered with infiltration of inflammatory cells which were ameliorated by BMSCs transplantation. In addition, BMSCs treatment also significantly reduced AI value, the level of VEGF, IL-17 and TNF-α as well as decreased RANK/RANKL expression and increased OPG level. In conclusion, BMSCs transplantation ameliorates inflammation and severity in arthritis rats possibly through regulation of RANK/OPG, indicating that it might be used for the treatment of arthritis patients.

Abstract Background Bone marrow mesenchymal stem cells (BM-MSCs) can dampen inflammation in animal models of inflammatory rheumatisms and human osteoarthritis. They are expected to be a solution for numerous human conditions. However, in rheumatoid arthritis (RA) and spondyloarthritis (SpA), subsets of subchondral BM-MSCs might conversely fuel synovitis and enthesitis. Main text Abnormal behaviour of BM-MSCs and/or their progeny has been found in RA and SpA. BM-MSCs also contribute to the ossifying processes observed in ankylosing spondylitis. Some synovial fibroblastic stem cells probably derive from BM-MSCs, but some stem cells can also migrate through the bare zone area of joints, not covered by cartilage, into the synovium. BM-MSCs can also migrate in the synovium over tendons. Sub-populations of bone marrow stem cells also invade the soft tissue side of enthesis via small holes in the bone cortex. The present review aims (1) to make a focus on these two aspects and (2) to put forward the hypothesis that lasting epigenetic changes of some BM-MSCs, induced by transient infections of the bone marrow close to the synovium and/or entheses (i.e. trained immunity of BM-MSCs and/or their progeny), contribute to the pathogenesis of inflammatory rheumatisms. Such hypothesis would fit with (1) the uneven distribution and/or flares of arthritis and enthesitis observed at the individual level in RA and SpA (reminiscent of what is observed following reactive arthritis and/or in Whipple’s disease); (2) the subchondral bone marrow oedema and erosions occurring in many RA patients, in the bare zone area; and (3) the frequent relapses of RA and SpA despite bone marrow transplantation, whereas most BM-MSCs resist graft preconditioning. Conclusion Some BM-MSCs might be more the problem than the solution in inflammatory rheumatisms. Subchondral bone marrow BM-MSCs and their progeny trafficking through the bare zone area of joints or holes in the bone cortex of entheses should be thoroughly studied in RA and SpA respectively. This may be done first in animal models. Mini-arthroscopy of joints could also be used in humans to specifically sample tissues close to the bare zone and/or enthesis areas.

Abstract Background Arctium lappa L. root (burdock root) has long been recommended for the treatment of different diseases in traditional Chinese medicine. Burdock root possesses anti-oxidative, anti-inflammatory, anti-cancer, and anti-microbial activities. The aim of the study was to elucidate whether aqueous extract of burdock root regulates mesenchymal stem cell proliferation and differentiation. Methods Human bone marrow-derived mesenchymal stem cells in 2D high density culture and in 3D micromass pellets were treated with chondrogenic induction medium and chondral basal medium in the absence or presence of aqueous extract of burdock root. The chondrogenic differentiation was accessed by staining glucosaminoglycans, immunostaining SOX9 and type II collagen and immuonblotting of SOX9, aggrecan and type II collagen. Results Treatment of aqueous extract of burdock root increased the cell proliferation of hMSCs. It did not have significant effect on osteogenic and adipogenic differentiation, but significantly enhanced chondrogenic induction medium-induced chondrogenesis. The increment was dose dependent, as examined by staining glucosaminoglycans, SOX9, and type II collagen and immunobloting of SOX9, aggrecan and type II collagen in 2D and 3D cultures. In the presence of supplemental materials, burdock root aqueous extract showed equivalent chondrogenic induction capability to that of TGF-β. Conclusions The results demonstrate that aqueous extract of Arctium lappa L. root promotes chondrogenic medium-induced chondrogenic differentiation. The aqueous extract of burdock root can even be used alone to stimulate chondrogenic differentiation. The study suggests that the aqueous extract of burdock root can be used as an alternative strategy for treatment purposes.
