Metabolic Bone Disorder

Abstract Background: Osteoporosis is a metabolic bone disorder that leads to low bone mass and microstructural deterioration of bone tissue and increases bone fractures. Resveratrol, a natural polyphenol compound, has pleiotropic effects including anti-oxidative, anti-aging, and anti-cancer effects. Resveratrol also has roles in increasing osteogenesis and in up-regulating mitochondrial biogenesis of bone marrow-derived mesenchymal stem cells (BM-MSCs). However, it is still unclear that resveratrol can enhance osteogenic differentiation or mitochondrial biogenesis of periosteum-derived MSCs (PO-MSCs), which play key roles in bone tissue maintenance and fracture healing. Thus, in order to test a possible preventive or therapeutic effect of resveratrol on osteoporosis, this study investigated effects of resveratrol treatments on osteogenic differentiation and mitochondrial biogenesis of PO-MSCs.Methods: The optimal doses of resveratrol treatment on PO-MSCs were determined by cell proliferation and viability assays. Osteogenic differentiation of PO-MSCs under resveratrol treatment was assessed by alkaline phosphatase activities (ALP, an early biomarker of osteogenesis) as well as by extracellular calcium deposit levels (a late biomarker). Mitochondrial biogenesis during osteogenic differentiation of PO-MSCs was measured by quantifying both mitochondrial mass and mitochondrial DNA (mtDNA) contents.Results: Resveratrol treatments above 10 µM seem to have negative effects on cell proliferation and viability of PO-MSCs. Resveratrol treatment (at 5 µM) on PO-MSCs during osteogenic differentiation increased both ALP activities and calcium deposits compared to untreated control groups, demonstrating an enhancing effect of resveratrol on osteogenesis. In addition, resveratrol treatment (at 5 µM) during osteogenic differentiation of PO-MSCs increased both mitochondrial mass and mtDNA copy numbers, indicating that resveratrol can bolster mitochondrial biogenesis in the process of PO-MSC osteogenic differentiation.Conclusion: Taken together, the findings of this study describe roles of resveratrol in promoting osteogenesis and mitochondrial biogenesis of human PO-MSCs suggesting a possible application of resveratrol as a supplement for osteoporosis and/or osteoporotic fractures.

Bone tissue engineering has developed significantly in recent years as there has been increasing demand for bone substitutes due to trauma, cancer, arthritis, and infections. The scaffolds for bone regeneration need to be mechanically stable and have a 3D architecture with interconnected pores. With the advances in additive manufacturing technology, these requirements can be fulfilled by 3D printing scaffolds with controlled geometry and porosity using a low-cost multistep process. The scaffolds, however, must also be bioactive to promote the environment for the cells to regenerate into bone tissue. To determine if a low-cost 3D printing method for bespoke SiOC(N) porous structures can regenerate bone, these structures were tested for osteointegration potential by using human mesenchymal stem cells (hMSCs). This includes checking the general biocompatibilities under the osteogenic differentiation environment (cell proliferation and metabolism). Moreover, cell morphology was observed by confocal microscopy, and gene expressions on typical osteogenic markers at different stages for bone formation were determined by real-time PCR. The results of the study showed the pore size of the scaffolds had a significant impact on differentiation. A certain range of pore size could stimulate osteogenic differentiation, thus promoting bone regrowth and regeneration.

The α-calcitonin gene-related peptide (α-CGRP) regulates bone metabolism and has potential applications in enhancing bone remodeling in vivo. However, α-CGRP's role in bone marrow mesenchymal stem cells (BMSCs) osteogenic differentiation remain unclear. Rat BMSCs were separated into control group, α-CGRP group and α-CGRP siRNA group, in which BMSCs were transfected with α-CGRP plasmid and α-CGRP siRNA respectively followed by analysis of α-CGRP level by real time PCR and ELISA, cell proliferation by MTT assay, Caspase 3 activity, ALP activity, formation of calcified nodules by alizarin red staining, Smad1 and Smad7 level by Western blot and Runx2 by real time PCR. αCGRP transfection into BMSCs significantly up-regulated CGRP, which could promote cell proliferation, inhibit Caspase 3 activity, promote ALP activity, increase calcified nodules formation and upregulate Smad1, Smad7 and Runx2 compared to control (P < 0.05); transfection of αCGRP siRNA significantly down-regulated CGRP in BMSCs, inhibited cell proliferation, promoted Caspase 3 activity, inhibited ALP activity, inhibited calcified nodules formation and downregulate Smad1, Smad7 and Runx2 (P < 0.05). αCGRP overexpression promotes the Smad/Runx2 signaling, which in turn promotes BMSCs proliferation and osteogenesis. Decreased αCGRP level inhibits Smad/Runx2 signaling, promotes BMSCs apoptosis, inhibits proliferation and osteogenic differentiation.

Bone marrow mesenchymal stem cells (BMSCs) can be differentiated into different types of cells. SOX9 involves in the development and progression of various diseases. Our study aims to assess SOX9's effect on osteogenic differentiation of BMSCs and its related regulatory mechanisms. Rat BMSCs were isolated and randomly divided into control group, SOX9 group and SOX9 siRNA group, which was transfected with pcDNA-SOX9 plasmid or SOX9 siRNA respectively followed by analysis of SOX9 expression by Real time PCR, cell proliferation by MTT assay, Caspase3 and ALP activity, GSK-3β expression and Wntβ/Catenin Signaling pathway protein expression by Western blot, and expression of osteogenic genes Runx2 and BMP-2 by Real time PCR. Transfection of pcDNA-SOX9 plasmid into BMSCs significantly inhibited cell proliferation, promoted Caspase3 activity, decreased ALP activity and downregulated Runx2 and BMP-2, increased GSK-3β expression and decreased Wntβ/Catenin expression protein expression (P< 0.05). SOX9 siRNA transfection significantly promoted cell proliferation, inhibited Caspase3 activity, increased ALP activity and upregulated Runx2 and BMP-2, downregulated GSK-3β and increased Wntβ/Catenin expression. SOX9 regulates BMSCs proliferation and osteogenic differentiation through Wntβ/Catenin signaling pathway.

Abstract Background Phosphate is the major ingredient of bone tissue, and is also an important component of commercial bone substitute materials, bone scaffolds, and implant surface coatings. With the dissolution of the bone substitute materials and the degradation by cells, local ion concentrations will change and affect bone tissue reconstruction. Bone marrow -derived mesenchymal stem cells (BM-MSCs) are main autologous cells to repair injured bone. When bone injure occurs, BM-MSCs migrate to the damaged area, differentiate into osteoblasts, and secrete bioactive factors to promote bone tissue repaired. This study aimed to investigate the effect of inorganic phosphate (Pi) at a series of concentration on migration and osteogenic differentiation of human bone marrow -derived mesenchymal stem cells(hBM-MSCs). Methods The culture of hBM-MSCs in mediums with different concentration of Pi from 2 mM to 10 mM were performed. HBM-MSCs migration were examined with transwell assays. HBM-MSCs proliferation were evaluated by cell counting kit-8 colorimetric method. Osteogenic genes expression were analyzed by real-time reverse transcriptase polymerase chain reaction. Mineralized nodules formation were demonstrated by Alizarin red staining. Result 4–10 mM Pi could effectively promote the migration of hBM-MSCs at 12 h and 18 h. There was no significant difference in the migration number of hBM-MSCs in Pi culture mediums at a concentration of 6, 8, and10mM. 2–10 mM Pi could promote the proliferation of hBM-MSCs to varying degrees in the observation period, while 4–10 mM Pi could promote the osteogenic differentiation and mineralization of hBM-MSCs. Conclusion The findings in our study showed 4-10 mM Pi could promote the migration, osteogenic differentiation, and mineralization of hBM-MSCs.

Abstract Background: Human bone marrow-derived mesenchymal stem (MSCs) cells are undifferentiated cells with the self-renewing ability and multi-lineage differentiation beneficial for regenerative medicine. Nano scaffolds are novel materials employed in bone repair and regeneration. Nisin is a prebiotic that can increase stem cells’ life span and proliferation. This study attempted to provide a proper strategy for bone marrow mesenchymal stem cells differentiation into the Osteocytes on a Poly‐L‐lactic‐acid scaffold (PLLA) after pretreating with probiotic Nisin. Methods: MSC osteogenic differentiation was evaluated by measuring Calcium, Alkaline phosphatase, and quantitative tests such as Real-Time PCR, Acridine Orange, Alizarin Red, Von Kossa, and others. Results: The result of the MTT test showed that the optimal dose of Nisin probiotic for the MSCs’ preconditioning was 200 IU/mL on the 1st, 3rd, and 5th days of culture. Real-time PCR data indicated that the expression rate of ALP, Osteonectin, Osteocalcin, and Collagen I have increased in the presence of Nisin, while the RUNX-2 gene expression has decreased. Furthermore, the results of Alizarin Red and Von Kossa tests, as well as Scanning electron microscopy (SEM), revealed that the cell proliferation in the preconditioned samples with Nisin increased significantly. Conclusions: The study concluded that the cell proliferation and differentiation increased in samples pretreated with Nisin on the PLLA Nano scaffolds.
