Full textReprogramming of a nuclear activity through nuclear transfer (NT) into enucleated oocytes gives rises to living animals although the developmental rate is very low. In the mouse the foetal development of clones is always accompanied by placental hypertrophy. The aim of our study is to understand the primary causes of cellular and molecular abnormalities at the origin of these trophoblast development problems. For this we have taken advantage of the possibility to derive trophoblast stem cells (TS) in vitro. We have derived and characterised TS cell lines from fertilised (TS) and cloned (ntTS) embryos. We have shown that ntTS cells are derived more efficiently and more rapidly than control TS cells. Our results show that ntTS cells are less dependent upon the embryonic factors essential for their self-renewal, FGF4 and Activin A highlighted in particular by the maintenance of self-renewal when the supply of these growth factors is reduced. Nevertheless, FGF4 and Activin pathways seem not to be directly altered in ntTS lines. We are facing a new phenomenon where ntTS cells display some properties close to cancerous cells while still being under control of their environment. Moreover our transcriptomic analyses show that the expression abnormalities observed in ntTS lines are well correlated with the early phenotypes of modified growth in ntTS cells, but could also give some clues about the implantation failures and the later placental defects exhibited by cloned foetuses. To conclude, the model of ntTS cells is particularly pertinent for studying the making-up of the placenta after cloning

Full textThe aim of this doctoral research project is the development of reliable and reproducible methodological approaches enabling the genetic characterization of circulating rare cells (CRC) isolated by ISET® filtration (Rarecells®, France). The first application developed consists in detecting mutations of the VHL (Von Hippel Lindau) tumor suppressor gene in single CRC isolated from the blood of 30 patients patients with clear cell renal cell carcinoma (ccRCC), assessed according to the results obtained by cytopathological analysis. In parallel, genetic analysis of VHL mutations was conducted in the corresponding tumor tissues. Results revealed a potential complementarity of the molecular genetic approach targeted to single cells with the reference method of cytopathological analysis and suggested that combining both strategies could improve the sensitivity of circulating cancer cells’ detection in patients with ccRCC. A second application consisted in the development of an innovative approach for non-invasive prenatal diagnosis of recessive genetic diseases by analysis of rare trophoblastic cells collected from the cervix. Finally, further developments allowed to optimize high-throughput sequencing analyses and to apply them to single CRC isolated by ISET®. This approach, combined with the isolation of living CRC, enabled us to obtain broader genetic data from the whole exome and should foster innovative applications to both predictive oncology and non-invasive prenatal diagnosis

Full textEmbryo implantation and placental formation are two essential steps in the beginning of a pregnancy. The extra-villous trophoblast and the cytotrophoblast differenciate during the first steps of placentation. The syncytiotrophoblast is the endocrine cell of the placenta. The role of the invasive extra-villous trophoblast is to anchor the placenta in the endometrium. During the implantation the placenta and the endometrium produce several hormones and cytokines that regulate the formation of these two cell types that are essential for placental functions. Adiponectin as an adipocytokine produced by the adipose tissue and circulating at high concentrations in human blood. The major role of adiponectin is to regulate the energy homeostasis. Moreover, in many other tissues, adiponectin exerts anti-proliferative, proinvasive and pro-differenciating actions. Adiponectin and its receptors AdipoR1 and AdipoR2 are present at the foeto-maternal interface. Thus, the placenta could be sensible to adiponectin. We aimed to determine the direct effects of adiponectin on placental functions. In the first part of this work, we demonstrated that adiponectin in vitro reduces proliferation of BeWo and JEG-3 cell lines. Secondly, we showed that adiponectin stimulates syncytiotrophoblast differentiation from villous trophoblast. Moreover, adiponectin upregulates the secretion of placental hormones as hCG and Leptin and the expression of the fusogenic protein syncytin-2. Finally, we showed that adiponectin stimulates extravillous trophoblast invasion by modulating the MMP/TIMP balance. This work thus shows for the first time that adiponectin is a new positive regulator of trophoblastic functions. Indead, adiponectine promotes the formation of a functionnal placenta with secretory capacities from the syncytiotrophoblast and anchoring capacities from the extra-villous trophoblasts

Full textThe prenatal diagnosis (PND) of genetic diseases is carried out by invasive techniques leading to a pregnancy loss going from 1 to 4 % of the cases. Aiming of carrying out a non-invasive PND, the research was directed towards new methods for obtaining fetal cells from maternal blood and cervical mucus at early stage of the pregnancy. We used a technique for trophoblastic cells isolation (ISET : Isolation by Size of Epithelial Trophoblastic cells). Our study was focused on the development of the non-invasive PND of cystic fibrosis (CF) by ISET method. The molecular strategy developed and applied to 12 couples at risk for the CF made it possible to carry out a correct diagnosis of all the studied cases. We also applied the method ISET to the transcervical cells obtained from cervical channel by cytobrush. We showed that this technique could be applied to the cervical samplings to carry out non-invasive PND

Full textRORyt is a transcription factor expressed by several populations of innate lymphoid cells (ILC), like lymphoid tissue inducer cells and NKR+RORyt+ cells that co-express RORyt and the NK cell receptor, NKp46. Here, we propose a model for RORyt+ ILC differentiation from the common lymphoid progenitor (CLP). Based on clonal assays of fetal liver CLP, we hâve shown that B, T, NK and RORyt+ cells are originating from a common progenitor. CLP lose B and T potential as they express a4b7 and CXCR6 respectively. The acquisition of RORyt occurs in the fetal liver. RORyt+precursors are observed in the blood and in the anlagen of peripheral organs. We have identified two distinct RORyt+ precursors that differentiate into RORyt+CCR6+ and NKR+RORyf cells. These precursors develop independently in the fetal liver. They are also observed in the spleen and the anlagen of mesenteric lymph nodes. We have also established the potential of these precursors in vivo by transfer into immunodeficient mice. The analysis of fate-mapping mice has shown that RORyt+-derived NK cells develop and are maintained in the peripheral organs of young adult mice. In adult mice, the bone marrow does not contain RORyt+ and in vitro cultures of bone marrow progenitors do not give rise to RORyt+ cells. Transfer experiments allowed us to identify the CLP as the progenitor of adult RORyt+ ILC. Populations that display a CLP phénotype are observed in the spleen and the lamina propria of adult mice. These peripheral CLP differentiate into RORyt+cells in vitro, indicating that the adult progenitor of RORyt+ ILC has to migrate to the periphery to receive the signal required for its differentiation

Full textInvariant natural killer cells T (iNKT) constitute a particular population of unconventional LT which expresses a semi-invariant TCRαβ receptor composed of the Vα14-Jα18 chain associated with the Vβ8, -7 or -2 chains in mice and which develops in the thymus. Thus, iNKT cells are able to recognize glycolipid antigens via their TCR presented by a non-polymorphic class I molecule: CD1d. These cells are known to be involved in various immune responses because of their ability to rapidly produce cytokines. However, like conventional SP T CD4+ lymphocytes, iNKT cells can differentiate into three phenotypes: Th1, -2 and -17. The iNKT1 subset also named conventional iNKT cells expresses receptors belonging to the NK lineage, is mainly located in the liver, thymus and spleen and produces mainly IFN-. The iNKT2 subset which until now remains insufficiently described, is localized preferentially in the lungs and produces mainly IL-4 and IL-13. The iNKT17 subset has been characterized in our laboratory as a subset of iNKT cells expressing the RORt transcription factor and capable of secreting IL-17 in response to IL-1 and IL-23 and located mainly in the peripheral lymph nodes and the skin. To date, only the development of conventional iNKT cells is well known while that of iNKT17 cells remains unknown. Thus, having noticed the low distribution of the iNKT17 cells present in the thymus of the C57BL/6 mouse compared to other iNKT cell subset, we were initially interested in explaining the causes of this poor distribution of this subset, as well as to define the acquisition sequence of its markers during its thymic development and peripheral migration. The results show that these cells have no defect of proliferation or response to cytokines of homeostasis that can explain their lower number in the thymus. In contrast, we found a lack of thymic accumulation of these cells that have the ability to migrate peripherally, accompanied by increased sensitivity to death by apoptosis and decreased expression of survival factors such as Bcl-2 which can explain their reduced number. Analyzes of their development at early stages showed a pre-established bias of their low number from the CD44- stage. The study of their ontogeny has shown a sequential acquisition kinetics of CCR6 and CD138 markers to establish for the first time a model of thymic maturation of this iNKT subset which was still unknown
