AbstractAdipose-derived mesenchymal stem cells (ADSCs) are promising candidate for regenerative medicine to repair non-healing bone defects due to their high and easy availability. However, the limited osteogenic differentiation potential greatly hinders the clinical application of ADSCs in bone repair. Accumulating evidences demonstrate that circular RNAs (circRNAs) are involved in stem/progenitor cell fate determination, but their specific role in stem/progenitor cell osteogenesis, remains mostly undescribed. Here, we show that circRNA-vgll3 originating from the vgll3 locus markedly enhances osteogenic differentiation of ADSCs; nevertheless, silencing of circRNA-vgll3 dramatically attenuates ADSC osteogenesis. Furthermore, we validate that circRNA-vgll3 functions in ADSC osteogenesis through a circRNA-vgll3/miR-326-5p/integrin α5 (Itga5) pathway. Itga5 promotes ADSC osteogenic differentiation and miR-326-5p suppresses Itga5 translation. CircRNA-vgll3 directly sequesters miR-326-5p in the cytoplasm and inhibits its activity to promote osteogenic differentiation. Moreover, the therapeutic potential of circRNA-vgll3-modified ADSCs with calcium phosphate cement (CPC) scaffolds was systematically evaluated in a critical-sized defect model in rats. Our results demonstrate that circRNA-vgll3 markedly enhances new bone formation with upregulated bone mineral density, bone volume/tissue volume, trabeculae number, and increased new bone generation. This study reveals the important role of circRNA-vgll3 during new bone biogenesis. Thus, circRNA-vgll3 engineered ADSCs may be effective potential therapeutic targets for bone regenerative medicine.

AbstractMesenchymal stem cells (MSCs) are important in regenerative medicine because of their potential for multi-differentiation. Bone marrow, chorion and placenta have all been suggested as potential sources for clinical application. However, the osteogenic differentiation potential of MSCs derived from chorion or placenta is not very efficient. Bone morphogenetic protein-2 (BMP-2) plays an important role in bone development. Its effect on osteogenic augmentation has been addressed in several studies. Recent studies have also shown a relationship between miRNAs and osteogenesis. We hypothesized that miRNAs targeted to Runt-related transcription factor 2 (Runx-2), a major transcription factor of osteogenesis, are responsible for regulating the differentiation of MSCs into osteoblasts. This study examines the effect of BMP-2 on the osteogenic differentiation of MSCs isolated from chorion and placenta in comparison to bone marrow-derived MSCs and investigates the role of miRNAs in the osteogenic differentiation of MSCs from these sources. MSCs were isolated from human bone marrow, chorion and placenta. The osteogenic differentiation potential after BMP-2 treatment was examined using ALP staining, ALP activity assay, and osteogenic gene expression. Candidate miRNAs were selected and their expression levels during osteoblastic differentiation were examined using real-time RT-PCR. The role of these miRNAs in osteogenesis was investigated by transfection with specific miRNA inhibitors. The level of osteogenic differentiation was monitored after anti-miRNA treatment. MSCs isolated from chorion and placenta exhibited self-renewal capacity and multi-lineage differentiation potential similar to MSCs isolated from bone marrow. BMP-2 treated MSCs showed higher ALP levels and osteogenic gene expression compared to untreated MSCs. All investigated miRNAs (miR-31, miR-106a and miR148) were consistently downregulated during the process of osteogenic differentiation. After treatment with miRNA inhibitors, ALP activity and osteogenic gene expression increased over the time of osteogenic differentiation. BMP-2 has a positive effect on osteogenic differentiation of chorion- and placenta-derived MSCs. The inhibition of specific miRNAs enhanced the osteogenic differentiation capacity of various MSCs in culture and this strategy might be used to promote bone regeneration. However, further in vivo experiments are required to assess the validity of this approach.

Potential Applicability

Thanks to stem cells’ capability to differentiate into multiple cell types, damaged human tissues and organs can be rapidly well-repaired. Therefore, their applicability in the emerging field of regenerative medicine can be further expanded, serving as a promising multifunctional tool for tissue engineering, treatments for various diseases, and other biomedical applications as well. However, the differentiation and survival of the stem cells into specific lineages is crucial to be exclusively controlled. In this frame, growth factors and chemical agents are utilized to stimulate and adjust proliferation and differentiation of the stem cells, although challenges related with degradation, side effects, and high cost should be overcome. Owing to their unique physicochemical and biological properties, graphene-based nanomaterials have been widely used as scaffolds to manipulate stem cell growth and differentiation potential. Herein, we provide the most recent research progress in mesenchymal stem cells (MSCs) growth, differentiation and function utilizing graphene derivatives as extracellular scaffolds. The interaction of graphene derivatives in human and rat MSCs has been also evaluated. Graphene-based nanomaterials are biocompatible, exhibiting a great potential applicability in stem-cell-mediated regenerative medicine as they may promote the behaviour control of the stem cells. Finally, the challenges, prospects and future trends in the field are discussed.

AbstractMultipotent porcine mesenchymal stem cells (pMSC) are indispensable for research and therapeutic use. Derivation and culture media might affect the selection of MSC subpopulation and thus the differentiation potential of cells. In this study we evaluated the effects of αMEM, aDMEM, M199, αMEM/M199, aDMEM/M199 and αMEM/aDMEM media on porcine bone marrow MSC derivation; pre-differentiation expression of ALP, COL1A1, SPP1 and BGLAP osteogenic marker genes at passage 5 and 10 pMSC; and differentiation potential of passage 5 pMSC. Morphological changes and matrix formation in osteogenic cells were evaluated by microscopical examination and calcium deposit in osteocytes was confirmed by Alizarin Red S staining. Results indicated media independent selection of different bone marrow MSC subpopulations with different surface marker gene expressions. Many pMSC subpopulations in different media had CD14+ expressing cells. We also observed basal media dependent changes in osteogenic markers expression and differentiation potential of pMSC. The αMEM/aDMEM media grown pMSC showed best osteogenic differentiation potential. We thus recommended the testing of αMEM/aDMEM mixed media in other species for pre-differentiation MSC culture that are intended for better osteogenic differentiation.SummaryPre-differentiation basal media influence osteogenic differentiation potential of mesenchymal stem cells (MSC). Among the tested media, αMEM/aDMEM was the best for pre-differentiation porcine MSC culture intending to use in osteogenesis.

Bone marrow mesenchymal stem cells (BMSCs) have self-renewal potential with multi-directional differentiation. Progranulin prevents bone degradation, inhibits inflammation and protects bone tissue. However, the role of Progranulin in osteoporotic BMSCs is unclear. Osteoporosis (OP) rat models were prepared by ovarian removal and treated with different doses (5 and 10 μM) of Progranulin followed by analysis of BMP-2 level by ELISA, bone mineral density and ALP activity. OP rat BMSCs were isolated and assigned into control group and Progranulin group followed by analysis of Progranulin level by ELISA, cell proliferation by MTT assay, RUNX2 and COL1A1 mRNA level by Real time PCR, and PI3K/Akt/PPARγ signaling protein level by Western blot. Progranulin treatment of OP rats dose-dependently increased BMP-2 expression, bone density and ALP activity. Compared with OP group, there were significant differences (P <0.05). Progranulin expression and BMSCs proliferation was increased, and RUNX2 and COL1A1 mRNA expression was elevated in Progranulin-treated OP group along with increased PI3K/Akt expression and decreased PPARγ protein expression. Compared with OP group, the difference was statistically significant, and the change was more significant with increasing concentration (P <0.05). Progranulin promotes BMSCs osteogenic differentiation and proliferation by regulating PI3K/Akt/PPARγ signaling pathway, which is beneficial for OP rats’ bone synthesis.

We aimed to explore the effects of rat bone marrow mesenchymal stem cells (BMSCs) on osteogenic differentiation via analyzing miR-3148 expression in patients with osteoporosis. Realtime quantitative PCR was conducted for assessing microRNA-3148 expression. BMSCs from SD rats were transfected with microRNA-3148 mimics and microRNA-3148 inhibitor via liposomal trans-fection method utilizing Lipo2000, followed by analysis of microRNA-3148 level. After 10-days of osteogenic differentiation induction, alkaline phosphatase (ALP) staining and alizarin red (ARS) staining were done to investigate the osteogenic differentiation potential. Simultaneously, qRT-PCR measured the expression of osteogenesis marker genes (BMP and Runx2) in each group. qRT-PCR analysis revealed a high expression of miR-3148 in the bone tissue and the serum samples from patients with osteoporosis in comparison with healthy individuals. In addition, miRNA-3148 mimics could retard the osteogenic differentiation of BMSCs, while microRNA-3148 inhibitor could prompt the procedure. MicroRNA-3148 was highly expressed in the skeletal tissues and the serum samples from patients with osteoporosis and it could restrain the differentiation of BMSCs into osteoblasts, suggesting that it might be a novel therapeutic target for treating osteoporosis.

ABSTRACTMultipotent porcine mesenchymal stem cells (pMSC) are invaluable for research and therapeutic use in regenerative medicine. Media used for derivation and expansion of pMSC may play an important role for the selection of MSC subpopulation at an early stage and thereby, the specific basal medium may also affect differentiation potential of these cells. The present study was undertaken to evaluate the effects of αMEM, aDMEM, M199, αMEM/M199, aDMEM/M199 and αMEM/aDMEM media on (1) porcine bone marrow MSC derivation; (2) expression of number of osteogenic markers (ALP, COL1A1, SPP1 and BGLAP) at 5th and 10th passage in pMSC before differentiation; and (3) differentiation of pMSC (at 5th passage) to osteogenic lineage. Morphological changes and matrix formation in osteogenic cells were evaluated by microscopic examination. Calcium deposits in osteocytes were confirmed by Alizarin Red S staining. Based on expression of different markers, it was evident that selection of bone marrow pMSC subpopulations was independent of basal media used. However, the differentiation of those pMSCs, specifically to osteogenic lineage, was dependent on the medium used for expansion of pMSC at the pre-differentiation stage. We demonstrated here that the pMSC grown in combined αMEM/aDMEM (1:1) medium expressed number of osteogenic markers and these pMSC underwent osteogenic differentiation most efficiently, in comparison to porcine mesenchymal stem cells grown in other media. In conclusion, osteogenic differentiation potential of pMSC maintained in αMEM/aDMEM medium was observed significantly higher compared to cells cultivated in other media and therefore, the combined medium αMEM/aDMEM (1:1) may preferentially be used for expansion of pMSC, if needed for osteogenic differentiation.

Advantages And Disadvantages

First discovered by Friedenstein in 1976, mesenchymal stem cells (MSCs) are adult stem cells found throughout the body that share a fixed set of characteristics. Discovered initially in the bone marrow, this cell source is considered the gold standard for clinical research, although various other sources—including adipose tissue, dental pulp, mobilised peripheral blood and birth-derived tissues—have since been identified. Although similar, MSCs derived from different sources possess distinct characteristics, advantages and disadvantages, including their differentiation potential and proliferation capacity, which influence their applicability. Hence, they may be used for specific clinical applications in the fields of regenerative medicine and tissue engineering. This review article summarises current knowledge regarding the various sources, characteristics and therapeutic applications of MSCs.Keywords: Mesenchymal Stem Cells; Adult Stem Cells; Regenerative Medicine; Cell Differentiation; Tissue Engineering.
