Повний текст джерелаDiabetes mellitus (DM) or the so called disease of the century is a life threatening dysfunction that affects the endocrine system. The mechanisms underlying the break in the feedback loop that regulates the metabolism and the consequent diabetes induction are not fully known. Understanding the mechanisms of insulin action is therefore crucial for the further development of effective therapeutic strategies to combat DM. Accordingly, it is imperative to find a robust and reliable model for diabetes research able to overcome the limitations of traditional 2D in vitro cell culture and animal experimentation. The aim of this thesis is to develop a new liver‐pancreas co‐culture model using advanced microphysiological systems (MPs) to tackle more effectively the mechanism involving the hepatic and pancreatic endocrine regulation. This work highlights the power of multi organ‐on‐chip systems that combines the advanced 3D‐cell compartmentalization, microfluidics and induced pluripotent stem cells (iPSC) technology to achieve a high biological complexity and functions that are rarely reproduced by only one of these tissue engineering technologies

Повний текст джерелаToday, one of the challenges for the pharmaceutical industry is to develop accurate in vitro liver models to improve the predictability of preclinical studies, in particular the study of the toxicity and efficacy of drug candidates. In recent years, tissue engineering, a multidisciplinary approach to develop tissues, has led to the development of new cell culture methods. Among them, cell cultures in 3D or in perfusion allowed to obtain hepatic activities similar to those observed in vivo. The objective of this thesis is to combine these two cell culture methods to create an even more accurate in vitro liver model. To do so, we are seeking to develop an alginate cryogel integrated into a microchip with mechanical properties adaptable to those of the liver depending on the physiological state to be reproduced (healthy or pathological liver).In the first part, we develop and characterize the alginate cryogel at the microscopic and macroscopic level, outside (cylindrical samples) and then inside the biochip. Three parameters are studied here: the cryopolymerization temperature, the alginate concentration and the quantity of cross-linking agents. Mechanical properties, porosity, absorption, pore interconnectivity and flow resistance are analyzed. The second part aims to culture liver cells within this new device. For this feasibility study the HepG2/C3A cell line is used. The results show viable and functional cells (albumin production, APAP transformation). In addition, we observe a 3D tissue structure, which is maintained after removal of the alginate cryogel. The last part aims to complexify the hepatic model, in particular by co-cultures. To get closer to the sinusoid structure, liver cells are cultured with endothelial cells (HUVEC) according to two approaches. In addition, the possibility to follow circulating tumor cells (MDA-MB-231) in the system is studied

Повний текст джерелаThe cancer metastatic process and its understanding have been a major topic of interest for researchers in the past. Using in-vitro models in both standard culture conditions and in microfluidic devices, we investigated the feasibility of such models in the representation of the physiological in-vivo situation. We developed a hierarchical coculture model in PDMS plates, composed of hepatocytes, pericytes and endothelial cells. In different culture conditions, the influence of the different cells composing the model on the adhesion of cancer cells and promyeloblastic cells was investigated as well as the influence on the inflammatory state of the culture. To reproduce the in-vivo blood flow and shear stress to which the endothelial cells and the adhering cells are subjected, the model was then transferred into a microfluidic biochip. The device was composed of three channels, separated by micropillars and which could be filled independently one from another. Pericytes embedded in a hydrogel, hepatocytes, endothelial cells and finally pancreatic cancer cells could be inserted successively to reproduce the in-vivo hierarchical situation. Cells were found to viable after the culture and markers related to the liver and inflammation to be expressed. The influence of the presence of hepatocytes and pericytes was investigated by varying the culture conditions. It was found that pancreatic cancer cells were attracted by the cells in other channels in coculture. The established models lay the bases for more complex and relevant systems that could complement their in-vivo counterparts in the drug discovery process

The liver regulates a myriad of vital functions including bile acid synthesis, hepatobiliary circulation, cholesterol homeostasis, drug metabolism, etc. This thesis focuses on the use of a 3D in vitro model of liver to study the effects of compounds and culture conditions on hepatobiliary transport and bile acid synthesis. In order to achieve this goal, protocols were developed to perform hepatic transport studies of bile acids in perfused 3D primary rat hepatocyte cultures. An established 2D sandwich culture model was used as a foundation for evaluation of variations in protocol parameters including culture medium composition and assay incubation times. In 2D sandwich cultures, dexamethasone (DEX) was essential for the formation of canalicular networks, whereas epidermal growth factor (EGF) disrupted the formation of these networks. Strikingly, EGF promotes cellular re-polarization and canalicular network formation in perfused 3D cultures, in contrast to its effect on 2D cultures. Perfused 3D cultures were found to have greater bile acid transport capabilities and closer to in vivo expression of certain liver transporters than 2D sandwich cultures on day 7. Perfused 3D cultures also had greater bile acid synthesis on day 7 than 2D cultures, however this was inhibited by EGF in both cultures. A numerical model was also developed for the reduction of experimental measurements necessary to determine pharmacokinetic parameters of hepatic transport, thus allowing for quantitative comparison of the effects of different culture conditions and culture platforms on transporter activity. The result of this thesis is the adaptation of a system for the study of hepatic transport and bile acid synthesis to 3D cultures. This system has also been previously shown to maintain other liver functions such as drug metabolism, and the work of this thesis thus allows for the concerted study of all these functions and potentially others.

Повний текст джерелаNanoparticles are defined as spherical structures with a maximum diameter of 100 nanometers. The application fields of nanoparticles including food and pharmaceutical industries are extremely broad. Human can be exposed daily to nanoparticles through various administration routes (oral, intravenous, pulmonary and cutaneous). Due to their size at the nanoscale, nanoparticles have unique physicochemical, inducing strong interactions with the biological environment. These features were widely exploited for the conception of nanomedicines for the diagnosis and the therapy. However, issues relative to their biological toxicity were addressed in the same time. This thesis work aims to investigate the potential toxicity of nanoparticles. Toxicological evaluation was performed using cell models adapted for the systemic and the oral routes. Mechanisms involved in the nanotoxicity were studied to identify toxicity factors. The first part of the work focused on the in vitro and in vivo hepatic toxicity of PLGA and silica nanoparticles. PLGA nanoparticles are used as drug carriers while silica nanoparticles play the role of anticaking agent in food industry and of pharmaceutical excipients. Their effects on the liver function and especially on the cytochrome P450 activity were investigated. The second part of the work consisted to study the impact of silica nanoparticles on the intestinal barrier, especially on the paracellular permeability and the integrity of the barrier. By emphasizing interspecies differences or the protective role of mucus, this project demonstrated that the choice of toxicological tools was crucial for a predictive nanotoxicity evaluation. Size, surface properties and composition were identified as major toxicity factors

This work is about the development of a physiologically relevant model of the human airway. Various factors such as the cell model, physiochemical factors such as the cell substrate properties including its stiffness, shear stress, stretch, the air-liquid interface and the biochemical factors in the medium influence the biology of the cells. The aim of this work is to closely approximate conditions in an in vivo situation by engineering the above conditions in to the in vitro platform. An assay to introduce the cell substrate properties was developed in a glass bottomed petri dish type culture as well as a microfluidic device culture. The influence of the cell substrate on airway epithelial cell monolayer formation was investigated in detail by changing the stiffness of the substrate independently by changing the gel concentration, the gel formation pH and the height of the gel from a hard substrate. Further, we found that biochemical growth factors have a huge role in cell monolayer formation. A real-time measurement of monolayer integrity using electrical resistance measurements was developed. A shear stress application platform was developed and a stretch application platform was designed. The applications of such a platform with the inclusion of various physiologically relevant factors include the study of physiologic evolution of microbes such as the influenza virus.

Повний текст джерелаIncludes bibliographical references.
The lack of correlation between in vitro and in vivo gene delivery experiments presents a significant obstacle in the progress of gene therapy studies by preventing the extrapolation of successful cell culture results into animals. This phenomenon has also been documented in the specific case of liver where standard hepatocyte culture systems fail to reliably predict the in vivo performance of gene delivery vectors. This is possibly a consequence of the loss of differentiated phenotype that these cells undergo when they are dissociated from their in vivo environment and cultured in vitro. This problem underscores the necessity for better in vitro models that can mimic the physiological environment and responses of in vivo liver tissue. This thesis aimed at developing an alternative in vitro gene delivery assay based on the Tissue-Engineered Liver Microreactor, a culture system designed to facilitate the morphogenesis of three-dimensional tissue-like structures from isolated liver cells under continuous perfusion, maintain cell viability and hepatic functionality for long-term culture periods and enable repeated in situ observation with microscopy. We developed experimental assays to non-invasively detect and quantify gene delivery efficiency in the 3D environment of the microreactor culture based on the application of 2-photon microscopy and spectroscopy.
(cont.) These techniques provide a convenient platform for comparative analysis of different vectors. Our main objective was to compare the gene delivery efficiency of an adenoviral vector (Ad5-CMV-EGFP) in the microreactor system and 2D hepatocyte monolayer culture. Quantitative assays were developed based on Real-Time PCR and RT-PCR to measure the levels of Ad vector uptake and transgene expression. The Ad mass transport in both systems was mathematically modeled to estimate the Ad uptake constant as a basis for comparison of delivery efficiency. This parameter was found to be significantly higher in the microreactor system, suggesting a more efficient mechanism of Ad internalization. Moreover, gene expression was measured in terms of transgene mRNA levels; the ratio of gene expression relative to Ad uptake was estimated as the basis for comparison of vector transcription efficiency. No significant difference was found between the 2 systems. These results provide some evidence that a more physiological culture system can yield different information (potentially more relevant to the in vivo situation) compared to standard in vitro culture.
