Project description:Long non-coding RNAs are emerging as key regulators of development and differentiation. In this study, we profiled TERT-immortalized human mesenchymal stromal cells (hMSC-hTERT20) cells undergoing osteogenic differentiation at 3 time points. We have identified expressed mRNAs and lncRNAs at each stage of differentiation.

Project description:hMSCs (Lonza) were differentiated towards adipocytes with three cycles of adipocyte differentiation induction and maintenance. hMSCs were differentiated towards osteocytes with osteogenic differentiation medium for 3 days and for 7 days. ArrayCGH experiments were performed before differentiation induction, after 2 and 3 cycles of adipogenic differentiation induction and after 3 days and 7 days of osteogenic differentiation induction.

Project description:We have established that BMP6 is an important endogenous regulator of human osteoblast differentiation. Our preliminary experiment showed that 8 hour BMP6 treatment induced early osteoblast markers in hMSC. In this study, we used microarrays to profile the global gene expression program in hMSC induced by BMP6 treatment and further identify the early osteogenic responses to BMP6 stimulation.

Project description:The aim of this study was to describe the gene expression patterns related to the differentiation and mineralization of bone-forming cells, including activation and/or repression of osteogenic or non-osteogenic pathways, remodeling of cell architecture, cell adhesion, cell communication, and assembly of extracellular matrix. The study implied patient selection, tissue collection, isolation and culture of human marrow stromal cells (hMSC) and osteoblasts (hOB), and characterization of bone-forming cells. RNA samples were collected at defined time points, in order to understand the regulation of gene expression during the processes of cell differentiation/mineralization that occur during bone repair. Transcriptome analysis was performed by using the Affymetrix GeneChip microarray technology platform and GeneChip® Human Genome U133 Plus 2.0 Array. Our results help to design a gene expression profile of bone-forming cells during specific steps of osteogenic differentiation. These findings offer an useful tool to monitor the behaviour of osteogenic precursors cultured in presence of exogenous stimuli, i.e. growth factors, or onto 3D scaffolds for bone engineering. Moreover, they can contribute to identify and clarify the role of new genes for a better understanding of the molecular mechanisms regulating osteogenesis. Experiment Overall Design: hMSC were derived from mononuclear cells (MNC) of bone marrow aspirates of four patients. MNC cultures were maintained in differentiation medium containing ascorbic acid-2 phosphate and dexamethasone, and hMSC were collected at different time points. The experimental protocol was specifically devised to mark five steps of hMSC differentiation (MD). The reference sample consisted in MNCs before the addition of differentiation medium (MD1).

Experiment Overall Design: hMSC were obtained from bone marrow aspirates of four patients. hMSC cultures were maintained in mineralization medium containing β-glycerophosphate, and collected at different time points. The experimental protocol was specifically devised to mark three steps of hMSC mineralization (MM). The reference sample consisted in confluent hMSCs before the addition of mineralization medium (MD4).

Project description:Differentiation of human skeletal stem cells (hMSC) into osteoblasts is regulated by a few well described transcription factors. Our study used clustering and gene expression data to identify a novel transcription factor. ZNF25, which we showed is involved in osteoblast differentiation. We used microarrays to study gene expression of hMSC-TERT4 cells during osteoblast differentiation.

Project description:We aimed in this study to identify the differentially regulated genes by Dlk1 in hMSC cells using microarray technology in order to gain a better understanding of Dlk1-mediated signaling pathways during hMSC differentiation. Both control (hMSC-TERT)(not expressing Dlk1) and Dlk1 overexpressing cells (hMSC-Dlk1) were cultured in triplicate at 3×104 cells/cm2 in Petri-dish in standard growth medium. At 90-100% confluence, highly purified total cellular RNA was isolated from each of three independent cultures per cell line using RNeasy Kit (QIAGEN Nordic, West Sussex, UK) according to the manufacturer?s instructions

Project description:The holistic nature of NMR enabled the time-course evolution of cholesterol, mono- and polyunsaturated fatty acids (including ω-6 and ω-3 fatty acids), several phospholipids (phosphatidylcholine, phosphatidylethanolamine, sphingomyelins, and plasmalogens), and mono- and triglycerides to be followed. Lipid changes occurred almost exclusively between days 1 and 7, followed by a tendency for lipidome stabilization after day 7. On average, phospholipids and longer and more unsaturated fatty acids increased up to day 7, probably related to plasma membrane fluidity. Articulation of lipidome changes with previously reported polar endometabolome profiling and with exometabolome changes reported here in the same cells, enabled important correlations to be established during hAMSC osteogenic differentiation. Our results supported hypotheses related to the dynamics of membrane remodelling, anti-oxidative mechanisms, protein synthesis, and energy metabolism. Importantly, the observation of specific up-taken or excreted metabolites paves the way for the identification of potential osteoinductive metabolites useful for optimized osteogenic protocols.
