| Study Title | Endo- and Exometabolome Crosstalk in Mesenchymal Stem Cells Undergoing Osteogenic Differentiation (Lipid Samples) |
| Study Summary | 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. |

| Project Title: | A Metabolomics-guided Bioreactor for Improved Engineered Bone Implants (BioImplant) |
| Project Type: | NMR-based untargeted metabolomics |
| Project Summary: | In an “omic” era, metabolomics offers exquisite insight into the complex metabolic network of living organisms and their adaptation mechanisms towards disease, therapy and environment. Metabolic markers (sets of metabolites) are emerging as new means of diagnostics, personalized follow-up and prediction of patient health status. Here, metabolomics is used for the first time to guide the development of a stem cell (SC) bioreactor to produce improved quality bone tissue for implantation. 3D porous scaffolds will be produced using biodegradable polymer poly-L-lactic acid (PLLA), both bare and collagen-coated to improve cell adhesion. These scaffolds will be 3D-printed with controlled architectures (both internally and externally), namely with struts alignment of 90o, with and without offset, expected to trigger distinct biological behaviors, particularly under mechanical cues. Scaffolds will be tested in a bioreactor for growth and differentiation of human mesenchymal SCs (hMSCs) into osteogenic lineage. hMSCs obtained from adipose tissue or bone marrow will be compared, as they have shown secretome differences and possible different potentials for osteogenic differentiation. The bioreactor will allow the application of controlled compression, to help mimic bone physiological conditions, and scaffold piezoelectricity will be studied in the same context. Scaffolds and physical cues will be tested in vitro (in osteogenic media) and monitored by biological measurements (proliferation, viability, differentiation indicators) and, for the first time, by cell metabolomics to identify the impact of each variable (scaffold composition, morphology, piezoelectricity and compression) on hMSC metabolism and define metabolic markers of hMSC function. Untargeted Nuclear Magnetic Resonance (NMR) metabolomics of cell extracts will identify dynamic metabolic cellular profiles associated to i) hMSC self-renewal and differentiation mechanisms, and their adaptations to ii) scaffold characteristics and iii) physical cues (compression and/or piezoelectricity). Statistical correlation of metabolic profiles with scaffold/bioreactor features and biological parameters will unveil metabolic markers of bioreactor performance and novel knowledge on SC osteogenic metabolism. Key metabolites will be identified as potentially osteogenesis-inducing, a role to be demonstrated using metabolite-tailored cell media to potentially substitute osteogenic growth factors and, thus, tackle related implantation challenges. Putative hypotheses of responsive hMSCs metabolic pathways will be validated through pathway network analysis, isotope-labeled tracers (NMR) and specific protein and genetic measurements. To our knowledge, this project proposes the first use of metabolomics to guide in vitro bone tissue engineering, building on recent proposals to exploit “omics” to understand, monitor and guide SC behavior for effective tissue engineering and implantation. |
