Texto completoScientists have explored various surface functionalization strategies to improve the biocompatibility of materials used in implantable devices, particularly in tissue engineering. For example, polydimethylsiloxane (PDMS), although used in many fields, has surface properties that are unfavorable for cell adhesion. Functionalization with extracellular matrix (ECM) proteins or synthetic peptides derived from ECM components improves cell adhesion. While these approaches offer some solutions, challenges such as production cost and control over 3D presentation limit their use. To overcome these challenges, we developed virus-like particles (VLPs) displaying bioactive peptides on their surface. The coat protein CP3, derived from the RNA bacteriophage AP205, was genetically modified at both its N- and C-termini to produce VLPs displaying adhesion peptides (RGD and YIGSR) and an osteogenic peptide (BMP2). The bioactivity of the VLPs was tested on PDMS with C2C12 myoblast cells, demonstrating enhanced cell adhesion, migration, proliferation, and differentiation. Heteromeric VLPs co-expressing RGD and YIGSR or BMP2 peptides showed combined bioactivity. By comparing focal adhesions formed by RGD VLPs and those formed by fibronectin, we elucidate both the similarities and the differences in cell interactions. These results demonstrate that AP205 VLPs can be used as nanoscale signaling platforms to stimulate multiple cell functions, with promising applications in nanomedicine and biomaterials

Texto completoDue to its interface position between the body and the environment, the lung is permanently agressed. Thus, repair process are essential part of lung homeostasis. Our hypothesis is that re-epithelialization by type II pneumocytes is a crucial phase of lung repair, which depend on extracellular matrix remodelling proceedings by extracellular matrix proteases, i. E. Metallo and serine proteases. We demonstrated that proteolytic cleavage of type I collagen by collagenaes, and induction of fibronectin and PAI-l by KGF, enhanced wound closure of lung alveolar epithelial in vitro, by increasing cell motility functions. Altogether, these works demonstrated the crucial functions of extracellular matrix rentodelling and extracellular matrix proteaees during proceedings of lung epithelial repair

Texto completoActually, it is well-established that maintaining the stemness character of stem cells or eliciting their lineage-specific differentiation is closely related to the nature of their microenvironment, known as stem cell niche. The extracellular matrix (ECM), a key component of stem cell niche, not only provides a support function for stem cells but also dictates their fate decision. From a rational point of view, a biomaterial intended to replace a damaged tissue should mimic the natural ECM in all its aspects, including its biochemistry, 3D structure, topography, porosity, rigidity…. etc. Unfortunately, the design of biomaterials that fully mimic the natural ECM is still a big challenge, due to its high structural and functional complexity. Towards the development of finely-tuned biomaterials, it seems important to start by deconstructing and then reconstructing the complexity of the ECM. In this context, the thesis project, herein, seeks to evaluate both the individual and the synergistic effect of different properties inherent to the natural ECM on human mesenchymal stem cells (hMSCs) osteogenic differentiation. Indeed, we investigated whether the biochemical composition of the ECM and the spatial distribution of its components modulate hMSCs osteogenesis. This was achieved by creating different artificial ECMs, in vitro, containing RGD and/or BMP-2 mimetic peptides, distributed randomly or as specific micropatterns on the surface of a model material

Texto completoIn order to achieve complex shapes during development, multicellular organisms need to coordinate cellular behaviors to form complex and functional organs. Identifying genes that are expressed in patterns that correlate with cellular processes is therefore primordial. Using the dorsal epithelium (the notum) of drosophila pupa as a model, my thesis aimed at uncovering the molecular mechanisms which control the spatial regulation of morphogenesis at the cell and tissue scale. First, I developed spatial transcriptomics which enabled the identification of new expression patterns involved in notum morphogenesis. Second, I developed, in collaboration with the imaging platform of Institut Curie, Rotating Sample Confocal Microscopy. Using this technique, I was able to simultaneously observe the morphogenesis of the notum, hinge and wing blade. This enabled the discovery of a new morphogenetic movement in the notum between 45-50hAPF. My results suggest that this extensive folding and elongation of the notum is independent of folding in the wing. Furthermore, I demonstrated that the expression of serine proteases regulate the attachment of the tissue to the cuticle which triggers the onset of the folding and determines the final shape of the tissue. Overall, this work increases our understanding of the spatial regulation of morphogenesis and contributes to the knowledge on how the extracellular matrix can regulate tissue shape

Texto completoBacillus subtilis is a ubiquitous gram-positive bacterium that lives in different terrestrial and aquatic environments. Various extracellular polymers involved in the composition of the B. subtilis biofilm matrix have been described. Polysaccharides are the basis of these mechanical properties, the viscoelasticity being modulated by the content of the biofilm in different extracellular polymers such as amyloid proteins and extracellular DNA.The aim of this work was to study the role of exopolymers in B. subtilis biofilms using the type CIP52.65T strain and various other wild, clinical and mutant strains. The composition of the matrix varies according to the presence of sucrose in the culture medium, so the effects of supplementation of the medium Trypticase Soy (TS) sucrose (20% w/v) were studied on the planktonic growth, matrix polymer production and biofilm formation for all these B. subtilis strains. Finally, among the proteins in the matrix, B. subtilis produces an amyloid-forming protein called TasA. Its exact role in the biofilm remains poorly understood. The purpose of this second study was to better understand the self-assembly mechanism of TasA and to understand its role in the matrix. By grouping all the characterizations carried out on the biofilms and the amyloid peptides, the biomimetic matrix design made it possible to carry out a first approach on the mechanical properties of this one, by reproducing artificial matrices based on exopolysaccharides (levan), amyloid peptides and DNA

Texto completoNeoangiogenesis, the formation of new blood capillaries from preexisting vessels, plays an important role in a number of physiological and pathological processes, particularly in tumor growth and metastasis. Extracellular proteolysis by matrix metalloproteinases or other neutral proteinases is an absolute requirement for initiating tumor invasion and angiogenesis. Cryptic segments or preexisting domains within larger proteins, most of them belonging to the extracellular matrix, can be exposed by conformational changes and/or generated by partial enzymatic hydrolysis. They can positively or negatively regulate important functions of endothelial cells including adhesion, migration, proliferation, cell survival and cell-to-cell interactions. Such regulations by cryptic segments and proteolytic fragments led to the concept of matricryptins and matrikines, respectively. Matrix metalloproteinases and matrikines in conjunction with other pro -or anti- angiogenic factors might act in concert at any step of the angiogenesis process. A number of matrikines have been identified as potent anti-angiogenic factors, which could provide a new alternative to anti-proteolytic strategies for the development of anti-angiogenic therapeutic molecules aimed at inhibiting tumor growth and metastasis. Some of them are currently being investigated in clinical trials
