Full textUpon removal of a portion of the esophagus, the restoration of the digestive continuity involves the surgical creation of an intrathoracic esophagogastric anastomosis. However, postoperative complications such as lung impairments, fistulas, strictures, graft necrosis, and gastroesophageal reflux are reported. The enhancement of surgical procedures for esophageal replacement has made promising progress by the development of a substitute through tissue engineering that utilizes a decellularized biological esophageal matrix (DEM). The primary objective of this study was to optimize the design of porcine DEM and characterize its biological and mechanical properties. The secondary objective was to cellularize DEM using readily available immune-privileged human mesenchymal stromal cells derived from Wharton's jelly (hMSCs-WJ).Esophageal decellularization was performed according to a protocol based on the dynamic perfusion of chemical and enzymatic solutions through the organ lumen. Histological analysis and residual DNA quantification of the DEM were conducted to determine the efficiency of the decellularization protocol. The ultrastructure of the DEM was analyzed using immunohistochemical (IHC) labeling, and the composition of the extracellular matrix (ECM) protein content was described by mass spectrometry. In-vitro cytotoxicity tests of DEM were conducted following ISO 10993-5 standards. The evaluation of suture retention strength, tensile strength, and bursting pressure of DEM aimed to describe the mechanical behavior of the substitute for clinical use.hMSCs-WJ used for DEM cellularization were extracted from human umbilical cords, and their flow cytometry profiling confirmed the purity of the cell population. The immune response of hMSCs-WJ was quantified after co-culture with peripheral blood mononuclear cells (PBMCs). PBMCs phenotyping assessed the expression of immune markers in contact with hMSCs-WJ, while enzyme-linked immunosorbent assay (ELISA) quantified cytokine release. The proposed DEM cellularization strategy involved the development of cell sheets from hMSCs-WJ. The validation of the cell sheet production protocol involved the characterization of the cellular phenotype by IHC analysis, and the mechanical study of the sheets measured their resistance to perforation.The absence of cellular content and residual DNA quantification in DEM confirmed the efficacy of decellularization according to current validation criteria. The ultrastructure and biological components of the ECM were preserved, and proteomic analysis highlighted protein complexity. Decellularization treatment did not induce DEM toxicity, and the mechanical behavior of DEM was suitable for its use as an esophageal substitute.Culturing hMSCs-WJ as cell sheets promoted the cellularization of the DEM. Once seeded, the sheets retained their cellular phenotype and immune-privileged characteristics. In-vitro tissue remodeling was visible, along with the formation of a new ECM produced by hMSCs-WJ.Characterization of the obtained DEM offered biological complexity and favorable mechanical behavior for its use as an esophageal substitute. DEM was cellularizable with hMSCs-WJ cell sheets, potentially promoting tissue integration and remodeling

Full textWe showed that keratocytes extracted from the perilimbic higher half of the corneal stroma have the maximum proliferative capacity, of which 70% express CD34. We optimized a medium for proliferation allowing to preserve CD34 positive phenotype. We highlighted 3 interactions of the components of the medium having an effect on differentiation. We carried out a stroma reconstruction and an hemicornea in which the diameter and the spacing of collagen fibres are close to those of the human cornea. Hemicornea was characterized and the interactions between the epithelial cells and the keratocytes bring a more physiological model in research and pharmacotoxicology. Its presentation inside culture inserts makes it possible to facilitate the application of products to be tested

Full textTears of the anterior cruciate ligament (ACL) are frequent. In absence of spontaneous healing, it is necessary to perform an autologous graft. In spite of clinical good results, some limitations remain. Within the framework of this project, we developed an new kind of tissue-engineered implant. The first part deals with the characterization of the cells extracted from the disrupted ACL. Then we present two models of ligament made of “small intestinal submucosa” (SIS), an acellular material of animal origin. The use of various cellular populations and several versions of SIS is discussed in the third part. Our results show that the cells of the disrupted ACL behave in vitro like those of the intact ACL. In addition, a hydrated form of SIS makes it possible to obtain a model with a morphology close to that of the ACL. The fourth part is devoted to an animal test which aimed to validate for the ACL a new protocole of implantation allowing a quicker integretion of the implant

Full textArticular cartilage is a highly specialized connective tissue that covers the end of bone and forms the smooth surface of joints. Articular cartilage is an avascular, alymphatic, aneural tissue that has limited self-healing capabilities. Cartilage can be altered by traumatic injuries, inflammatory or degenerative diseases. Current surgical treatments for cartilaginous defects only allow to obtain short-term satisfactory results. Therefore strategies for long-term cartilage repair have been developed. These tissue engineering strategies are based on the use of chondrogenic cells, biomaterials and morphogens. In this context, we investigated the combined use of stem cells from human adipose tissue (hATSC) and a silated cellulose-based injectable self-setting hydrogel (Si-HPMC). First we have shown that hATSC exhibit stem cells features. We have then demonstrated that hATSC cultured within a 3D environment provided by Si-HPMC and in the presence of inductive medium, express a chondrocytic phenotype and are able to form a cartilaginous tissue in vivo. In order to optimize the chondrogenic differentiation of hATSC, we were finally interested in deciphering the potential roles of hypoxia and a marine polysaccharide GAG-mimetic (GY785 DRS) to improve chondogenic differentiation of hATSC. These two factors have emerged as potential tools to optimize the chondrogenic differentiation for use in regenerative medicine of cartilage

Full textDegenerative hurts of skeletal tissue affect an important part of the population and represent a major stake in health care. However, the therapeutic approaches for the repair of these tissues, suffer from numerous limitations. In this context, a multidisciplinary efforts has been done to develop alternative therapeutic solutions, leading to a new discipline; tissue engineering. This discipline has for objective to develop biological substitutes, by developing hybrid constructs associating three-dimensional matrices with cells. The goal of this thesis was to estimate the potential of two exopolysaccharides (EPS) from marine origin HE800 and GY785 in skeletal tissue engineering. During a first study, we set up a sterilization method adapted to marine EPS. Then, toward the development of physically and biologically competent 3 D matrices, we demonstrated in the second study that the association of EPS to a sililated hydroxypropyl methylcellulose (Si-HPMC) increases the mechanical properties of the scaffold. The third study deepened on the biological properties of the GY785/Si-HPMC scaffold on cartilage tissue engineering with rabbit articular chondrocytes (RAC). Results indicate the ability of this scaffold to maintain and to recover a chondrocytic phenotype as well as the production of cartilage-like extracellular matrix. The results of these works show the interest of marine EPS in tissue engineering and more particularly, the significance of GY785 EPS in cartilage tissue engineering

Full textCartilage can be altered by traumatic injuries, inflammatory or degenerative diseases. To address this clinical issue, cartilage tissue engineering strategies combining cells, biomaterials and morphogenic factors are promising. Our strategy associates adipose stem cells (ASC) with an injectable and self-setting hydrogel. The aim of the present study was to determine the optimal culture conditions to promote the chondrogenic differentiation of ASC and therefore the formation of a cartilaginous matrix in vitro and in vivo. Our approach was based on the use of morphogenic factors mimicking the articular cartilage environment. Thus, we were interested in deciphering the effects of the dimensionality, oxygen tension and glycosaminoglycanesmimetics on the chondrogenesis of ASC for their future use in cartilage engineering

Full textTissue Engineering aims to fabricate bio-prostheses by regenerating or culture, in vivo or in vitro, tissues or organs. In the in vitro strategy, developing new tools such as bioréactors which allow the culture of cells or tissues under their specific mechanical solicitations is a huge point. Moreover, the last advances of this discipline in regeneration of tissues require new mechanical model allowing their evaluation and comparison to native tissue under physiological loading. Indeed, in order to obtain a good evaluation of their mechanical quality, it is important to be able to applied mechanical solicitations linked to physiological ones. As a first step, a bioreactor of ligament allowing the culture of cells under mechanical solicitations of cyclic traction-torsion was designed and developed. This bioreactor was sized to potentially obtain a bio-prosthesis comparable to native tissue in term of size (4 to 5 cm long). In a second time, a mechanical model was elaborated based on a thermodynamic formalism developed in our laboratory and the observation made on rabbit Achilles tendons. The goals of this model are to improve our knowledge on the mayor structures involved into the mechanical quality of theses tissues and to evaluate and optimise the scaffolds and neo-tissues of substitution
