Texte intégralOsteoarthritis (OA) is the most common rheumatic disease in the world and represents the first cause of disability in the world. OA results from the loss of balance between degradation and repair inside cartilage, in favor of degradation, with increased activity of catabolic enzymes such as matrix metalloproteinases and decreased production of ECM proteins. Chondrocytes are responsible for the repair and biosynthesis of elements of the extracellular matrix. Experimental findings support the hypothesis that diabetes is an independent risk factors for OA. However, correct molecular mechanisms underlying the diabetes-associated OA phenotype is still largely unknown. Firstly chondrocytes cell growth, ROS levels and apoptosis were analyzed using different glucose concentration. Results shown that chondrocytes prefer 2.5 mM of glucose which was used as normal glucose concentration and 25 mM of glucose was used as high glucose concentration. ROS levels and cell death increase in chondrocytes growth in high glucose environment. Also cytoskeletal network is more disorganized in C28/I2 cells growth at high glucose concentration, this correlates with different RalA-GTP levels which is involved in the regulation of cytoskeletal organization. Experiments were performed even using medium supplemented by ITS (Insulin-transferrin-selenium) to promote chondrocyte differentiation and IL-1β was used to simulate osteoarthritic cartilage environment. Ral A-GTP levels are lower in cells grown in 25 mM of glucose and stimulated with IL1β. Levels of p-ERK1/2 decrease in cells grown at high glucose concentration and in cells stimulated with IL1β. Furthermore, NF-κB, iNOS and LC3II levels were evaluated. Results demonstrate that high glucose media block autophagic process in chondrocytes. Effect of glucose concentration on human primary chondrocytes cells was evaluated after only 24 h to understand which signaling pathways is activated by high glucose environment. Phosphorylation of ERK1/2, p38, Akt and p65 is altered in chondrocytes growth at high glucose concentration and this correlates with an increase secretion of MMP-13. To better analyze the role of ROS levels in the chondrocytes I worked for 6 months in the Dr. Loeser Lab at the School of Medicine in the University of North Carolina at Chapel Hill; one of the best lab in the cartilage biology field. I worked on PRX6 which is involved in the recovery from H2O2. Oxidation state of PRX6 was evaluated in chondrocytes treated with different stimuli, like H2O2, Fn-f, menadione (men) and DMNQ. After this experiment, we wanted to see if PRX6 could impact the MAPK signaling pathways in cells treated with IGF-1, menadione, combination of menadione and IGF-1 and with Fn-f. Localization of PRX6 was analyzed using nuclear and cytoplasm extraction. Then I worked in collaboration with Prof. Laura Cipolla and Prof. Maddalena Collini to develop and characterized a new gelatin-based hydrogel using Diethylsquarate as crosslinker.

Texte intégralTissue engineering aims to replace lost, damaged or failing tissue and organs, starting with cultured proliferating cells and ending with tissue-like structures. The extracellular matrix (ECM) plays a pivotal role in determining cell behavior during tissue remodelling processes leading to complete differentiated structures. Therefore it is desirable to control cell differentiation during tissue regeneration by mimicking the ECM using engineered biomaterials. To modify the biophysical and mechanical properties of these biomaterials can be used as a strategy to elicit specific cellular responses. Moreover, an injectable hydrogel biomaterial, having such capabilities, should have the advantage to be easily engrafted in vivo in order to carry stem cell and/or bioactive molecules to promote tissue renewal. Our research is thus focused on the use of an injectable hydrogel made from polyethylene glycol (PEG) conjugated to Fibrinogen. The PEG-Fibrinogen (PF) is used as scaffold for in vitro muscle reconstruction, seeded and cultured with mesoangioblasts (vessel associated progenitor cells) and freshly isolated muscle satellite cells (SCs). The PF, which can be controlled in terms of its matrix modulus, is tested in vivo as mesoangioblast carrier for muscle regeneration. The PF scaffold used for in vitro 3-D cultures promoted good survival of miogenic precursors and accelerated skeletal muscle differentiation (contractile myotubes) within 24 hours (normally, 2-D cultures take three days to exhibit myotube formation). The confining geometry of the microchannels created with microablation in the PF scaffolds promoted the development of oriented mature muscle fibers. Sub-cutaneous PF/miogenic precursors implants in Rag2 Chain -/- mice were able to form a “muscle organoid”. Finally, in vivo experiments using PF as a cell carrier showed increased transplanted cell survival, ameliorated in situ cellular retention and an overall improvement in cell engraftment. Injectable hydrogel biomaterials can be readily applied for skeletal muscle cell delivery by a simple one-step injection procedure and could have a noteworthy impact in the treatment of muscular dystrophy.
