Objective Previously, we demonstrated the importance of transforming growth factor-β (TGFβ)-activated SMAD2/3 signaling in chondrogenesis of bone marrow–derived mesenchymal stem cells (BMSCs). However, TGFβ also signals via the SMAD1/5/9 pathway, which is known to induce terminal differentiation of BMSCs. In this study, we investigated whether other SMAD2/3-activating ligands, Activin and Nodal, can induce chondrogenic differentiation of BMSCs without inducing terminal differentiation. Design Activation of SMAD2/3 signaling and chondrogenesis were evaluated in human BMSCs ( N = 3 donors) stimulated with TGFβ, Activin, or Nodal. SMAD2/3 activation was assessed by determining phosphorylated-SMAD2 (pSMAD2) protein levels and SMAD2/3-target gene expression of SERPINE1. Chondrogenesis was determined by ACAN and COL2A1 transcript analysis and histological examination of proteoglycans and collagen type II. Results Both Activin and TGFβ enhanced pSMAD2 and SERPINE1 expression compared to the control condition without growth factors, demonstrating activated SMAD2/3 signaling. pSMAD2 and SERPINE1 had a higher level of expression following stimulation with TGFβ than with Activin, while Nodal did not activate SMAD2/3 signaling. Of the 3 ligands tested, only TGFβ induced chondrogenic differentiation as shown by strongly increased transcript levels of ACAN and COL2A1 and positive histological staining of proteoglycans and collagen type II. Conclusions Even with concentrations up to 25 times higher than that of TGFβ, Activin and Nodal do not induce chondrogenic differentiation of BMSCs; thus, neither of the 2 ligands is an interesting alternative candidate for TGFβ to induce chondrogenesis without terminal differentiation. To obtain stable cartilage formation by BMSCs, future studies should decipher how TGFβ-induced terminal differentiation can be prevented.

Abstract Aging is associated with the development of various chronic diseases, in which both hypertension and osteoarthritis (OA) are dominant. Currently, there is no effective treatment for OA, whereas hypertension is often treated using L-type voltage-operated calcium channel (VOCC) blocking drugs, nifedipine being among the most classical ones. Although nifedipine together with other VOCC inhibitors plays an important role in people wellbeing, there are unresolved questions on its possible effect on cartilage tissue homeostasis and the development of OA. Due to that, the aim of this study was to analyse the effects of nifedipine on metabolic processes in human chondrocytes and bone marrow mesenchymal stem cells (BMMSCs). To analyze whether those events were mediated specifically through VOCC, agonist BayK8644 was used. Our results demonstrate that nifedipine downregulated chondrocyte proliferation rate as well as mitochondrial respiration and ATP production (Agilent Seahorse) in both cell types. Analysis of cartilage explant histological sections by electron microscopy also suggested that part of mitochondria lose their activity in response to nifedipine.However, switch of energetic metabolic pathway towards glycolytic was observed only in chondrocytes. Stimulation with either nifedipine or BayK8644 resulted in elevated production of collagen type II and proteoglycans in micromass cultures under chondrogenic condition, although the effects of VOCC inhibitor Bay8466 were less expressed. Nitric oxide (NO) activity, as measured by flow cytometry, was upregulated by nifedipine in BMMSCs and particularly chondrocytes, suggesting that NO at least in part may account for the effects of nifedipine on metabolism in both tested cell types.Taken together, we conclude that antihypertensive drug nifedipine inhibits mitochondrial respiration in both chondrocytes and BMMSCs and that these effects may be associated with increased NO accumulation and pro-inflammatory activity. Glycolytic capacity was enhanced only in chondrocytes, suggesting that these cells have the capacity to switch from oxidative phosphorylation to glycolysis and alter their metabolic activity in response to VOCC inhibition. Finally, nifedipine stimulated production of collagen type II and proteoglycans in both cell types, implying its potentially beneficial anabolic effects on articular cartilage. These results highlight a potential link between consumption of antihypertensive drugs and cartilage health

Abstract Background: Due to its low capacity for self-repair, articular cartilage is highly susceptible to damage and deterioration, which leads to the development of degenerative joint diseases such as osteoarthritis. Menstrual blood-derived mesenchymal stem cells (MenSCs) are much less characterized compared to bone marrow mesenchymal stem cells (BMMSCs). However, MenSCs seem an attractive alternative to classical BMMSCs due to ease of access and broader differentiation capacity. The aim of this study was to evaluate chondrogenic differentiation potential of MenSCs and BMMSCs stimulated with transforming growth factor β (TGF-β3) and activin A, member of the TGF-β superfamily of proteins.Methods: MenSCs (n=6) and BMMSCs (n=5) were isolated from different healthy donors. Expression of cell surface markers CD90, CD73, CD105, CD44, CD45, CD14, CD36, CD55, CD54, CD63, CD106, CD34, CD10, Notch1 was analysed by flow cytometry. Cell proliferation capacity was determined using CCK-8 proliferation kit. Adipogenic differentiation capacity was evaluated according to Oil-Red staining, osteogenic differentiation - Alizarin Red staining. Chondrogenic differentiation (Activin A and TGF-β3 stimulation) was induced in vitro and in vivo (subcutaneous scaffolds in nude BALB/c mice) and investigated by histologically and by expression of chondrogenic genes (collagen type II, aggrecan). Activin A protein production was evaluated by ELISA.Results: MenSCs exhibited a higher proliferation rate, as compared to BMMSCs, and a different expression profile of several cell surface markers. Activin A stimulated collagen type II gene expression and glycosaminoglycan synthesis in TGF-β3 treated MenSCs but not in BMMSCs, both in vitro and in vivo, although the effects of TGF-β3 alone were more pronounced in BMMSCs in vitro. Conclusion: These data suggest that activin A exerts differential effects on the induction of chondrogenic differentiation in MenSCs vs. BMMSCs, which implies that different mechanisms of chondrogenic regulation are activated in these cells. Following further optimisation of differentiation protocols and the choice of growth factors, potentially including activin A, MenSCs may turn out to be a promising population of stem cells for the development of cell-based therapies with the capacity to stimulate cartilage repair and regeneration.Trial registration: Not applicable.

Micro Pattern

The mechanical stimulation from extracellular matrix could regulate physiological behavior of cells through the mechanism of mechanotransduction. Previous researches had shown that apoptosis could be regulated by the size of the cell adhesion area.However, the regulation of cell apoptosis by different adhesion shape with the same area is still unclear. This workfocused on the regulation of apoptosis for bone marrow mesenchymal stem cells (MSCs) by different circularity and area of adhesion geometry. We manufactured micro-pattern surface which was suitable for adhesion of MSCs by the technique of micro-contact printing. Three typesof geometry for individual is land of micro-pattern were designed. We adopted terminal-deoxynucleoitidyl transfer as emediated nick end labeling (TUNEL) method to detectcell apoptosis. This research shows that the adhesion geometry which has smaller area and greater circularity will promote apoptosis of MSCs. This indicates that MSCsmay prefer to live on the surface without any restrict. Ourstudies focused on the significantly important problem about interaction between extracellular matrix and physiological behavior of mesenchymal stem cells.
