Der volle Inhalt der QuelleThe lymphatic system is a unidirectional vascular network transporting lymph, enabling drainage of interstitial fluids, transport of intestinal lipids, and also immune monitoring and tolerance. Nevertheless, the lymphatic system is involved in many pathologies, and particularly in tumor progression. Indeed, the lymphatic system promotes the metastatic spread, carried by lymphatic vessels to distant organs. More recently, the lymphatic system has been identified as a key regulator of immune responses during tumor development. The immune system is essential for tumor detection and establishment of anti-tumor lymphocyte responses. However, at advanced stages of tumor development, immune escape mechanisms are established in favor of tumor growth. These mechanisms are mediated not only by tumors themselves, but also by various players in the tumor environment. The lymphatic system is one of these players, particularly found in breast tumor environment. Advanced-stage breast adenocarcinomas respond to immunotherapies that target immune checkpoints responsible for immune escape. Indeed, the lymphatic system potentiates tumor response to these immunotherapies, playing a dual role in immunomodulation in the tumor context. Lymphatic vessels are able to recruit T cells to the tumor site to stimulate anti-tumor immune surveillance, but are also able to generate T cell immunosuppressive mechanisms through the expression of immune checkpoints. During my thesis, I therefore studied immunomodulatory mechanisms of the lymphatic system during mammary tumor development. I observed that the lymphatic system controls a switch from immune surveillance to immunosuppression, particularly induced by ligands of TIGIT immune checkpoint. I have shown that activation of tumor lymphatic vessels leads to overexpression of Nectin-2, which inhibits T cells overexpressing TIGIT. This in turn reduces cytotoxic CD8+ T cell responses to promote tumor growth

Der volle Inhalt der QuelleWomen’s nutrition can have long-term effects on mammary development and on the development and the health of the offspring. Leptin may play a major role during these processes. In the present work we show that leptin synthesis in the mammary gland slightly increases during pregnancy, but largely increases during lactation. We also show that, in the rabbit, milk consumption from obesogenic-fed dams promote the later effects of an obesogenic diet and leads to an abnormal mammary development observed in the offspring. We also highlight the synthesis and the mammary secretion of leptin in a heterologous cellular model. We also evaluate the intra-species variability as well as the growth considering two nutritional windows: obesogenic feeding from the puberty or from the birth, in two lineages of mice, FVB/N and C57BL /6.This work shows that the consumption of altered maternal milk has long-term effects by influencing the growth and the mammary development of the offspring, in rabbit

Der volle Inhalt der QuelleNutritional status, mostly during childhood and adolescence, can induce long-term effects in particular on mammary gland development. The mechanisms underlying this phenomenon still remain unknown. We have first studied leptin gene expression inrabbit mammary gland. The real time RT-PCR quantitative analysis showed that the leptin mRNA level rose from the end of pregnancy to reach at mid-lactation, a level equal to that of the adipose tissue, while leptin receptor mRNA concentration was higher during pregnancy as compared to lactation. Cellular localization of leptin reveals an expression in the luminal epithelial cells. These results suggest that leptin, through an autocrine and/or a paracrine role, could participate in the local regulation of mammary gland development. We then analyzed the consequences of adiposity on lactation and on offspring’s mammary gland development in the rabbit. We showed first that the obesogenic diet alters milk composition and second that this altered milk could lead to mammary alterations in the offspring. These results support the hypothesis that maternal milk, which composition can change according to the maternal diet, may have long-term effects on offspring’s mammary gland development

Der volle Inhalt der QuelleStem cells (SC) drive mammary development, giving rise postnatally to an epithelial bilayer composed of luminal and basal myoepithelial cells. The molecular identity of SCs and the factors regulating their function remain poorly defined. We identified the transmembrane protein, Podoplanin (Pdpn), as a specific marker of the basal compartment, including multipotent SCs, and found Pdpn localized at the basal-luminal interface. Embryonic deletion of Pdpn targeted to basal cells diminished basal and luminal SC activity and affected expression of several Wnt/b-catenin (Wnt/b-cat) signaling components. Moreover, Pdpn deletion attenuated mammary tumor formation in a mouse model of b-cat-induced breast cancer, limiting tumor-initiating cell expansion and promoting molecular features associated with mesenchymal-to-epithelial cell transition. In line with the loss-of-function data, we demonstrated that mechanistically, Pdpn enhanced Wnt/b-cat signaling in mammary basal cells. Overall, our study reveals a role for Pdpn in mammary development and tumorigenesis through the control of Wnt/b-cat-responsive SCs

Der volle Inhalt der QuelleControl of husbandry management is essential to produce female goat kids that fully express their milk potential during their career. It involves the determination of key periods during growth, particularly for the mammary gland development. The objective of this thesis was to determinate the effects of early weaning combined with different post-weaning feeding strategies on the performances of alpine goat kids as well as on their mammary gland development. On the one hand, we showed that early weaning at 10 kg of body weight did not affect body development, reproductive parameters or milk production (MP). On the other hand, a high concentrate intake during the rearing period increased body development and the weight of mammary glands.However, this did not impact the development of mammary parenchyma during the pre-pubertal phase or at the beginning of gestation, nor even the proportion of Mammary Epithelial Cells (MEC). The proliferation of MEC was identical regardless of the amount of concentrate ingested. MP was not affected by increasing concentrate intake. Modifying the energy and protein concentration of the concentrate in the pre-pubertal period had no effect on growth, reproductive performance, mammary gland development or mammary parenchyma development. Therefore, goats seem to adapt to changes in feeding strategies without a negative effect of the increase in growth on their ability to produce milk

Der volle Inhalt der QuelleNewborn rabbits (Oryctolagus cuniculus) are dependent of maternal odour cues to localise the nipples and to suck. During a nursing episode, they display a typical behaviour under the mother’s abdomen constitutedby searching movements of the head usually followed by oral grasping movements. Such responses are in particular released by the mammary pheromone (MP) emitted by lactating females. They may also be induced bya novel odorant after it has been learned by association with the MP. In this context, three objectives have beenpursued in the present thesis: the assessment of the impact of the satiation and of the rabbit pup development on 1) the releasing activity of the MP, 2) the reinforcing impact of the MP on an initially neutral odorant; and 3) the evaluation of the long term impact of the releasing and reinforcing functions of the MP during the development of the young rabbit. 1) During the first postnatal days, the ability of the MP to trigger the orocephalic movements of the pups appears independent of the prandial state. Then, a progressive transition from an “automatic” response to the MP to a response regulated by post-ingestive or post-absorptive factors occurs. Indeed, the response to the MP remains very high along the 24-h cycle on d2, but on d5 the MP is highly active only right before the daily nursing. Moreover, an evolution in the morphology of the response to the MP appears between birth and weaning. 2) The potency of the MP to induce odour-learning is affected by the prandial state as soon as d0. Inaddition, this reinforcing function vanishes after d4, suggesting the presence of a sensitive period for the reinforcing activity of the MP. 3) The neonatal learning of a new odorant seems to impact the behaviour of young rabbits (around 30-day-old) tested for their social preferences, but not for their feeding ones. But this retention seems to require a stronger reinforcement (nursing) than that resulting from the exposure to the MP only. These results open perspectives for the study of the mechanisms engaged in the learning of the mammal newborn and of their consequences in the short as the long term, in particular through the action of pheromonal and of multi-sensory reinforcers dependent of the mother that contribute to the adaptation of the young

Der volle Inhalt der QuelleMicroRNA are small non-coding RNA that have been found to play important roles in silencing target genes and that are involved in the regulation of various normal cellular processes. Few studies have described their implication in mammary gland biology, mainly focusing on pathological situations allowing the characterization of microRNA as markers of tumour class in breast cancer. The involvement of microRNA in the regulation of normal mammary gland biology remains to be uncovered. To understand the function of microRNA in the different steps of mammary gland biology we developed three approaches: 1/ Identification of organ- and tissue- (testicles) specific microRNA suggest the existence of specific microRNA in the mammary gland. These microRNA have been investigated by creating a bank of small RNA. Twenty four new microRNA were cloned, of which 6 are specific for the mouse (Sdassi et al. , 2009). The expression profiles of these new microRNA were analysed by qRT-PCR, to allow for better characterization. 2/ Conditional invalidation (system Cre-loxP) of Dicer, one of the key enzymes involved in the microRNA maturation. The inactivation is achieved mainly in the mammary epithelial cells by the use of an MMTV-Cre and WAP-Cre transgenic lines crossed with Dicerfl/fl mice. The heterozygote Dicerfl/+/MMTV-Cre mice present a defect of lactation. Histological observations show a default of mammary gland development detectable from 6 days of gestation onwards. Transcriptomic studies will be conducted to further characterize the affected signaling pathways. The Dicerfl/fl/WAP-Cre KO mice also exhibit a defect of lactation. The histological studies show abnormalities in mammary gland development at 18 days lactation. The genes regulated by microRNA in this model will be characterized by transcriptomic studies. 3/ The characterization of microRNA expression patterns at different physiological stages of the mammary gland development in mice has been described (Silveri et al. , 2006; Sdassi et al. , 2009). The role of one of these microRNA (miR-30b) is currently being analyzed by studying the phenotype of transgenic mice which over express this microRNA in mammary epithelial cells. The females present a defect of lactation associated with a default of this tissue morphology that is observed from the end of gestation onwards. Transcriptomic studies are underway to identify signaling pathways involved in this phenotype as well as the targets of this microRNA in the mammary gland. However, histological analysis did not show any developmental abnormalities associated withdefects of lactation. A remodeling defect of the mammary gland was found in these mice during involution. Transcriptome analysis has identified genes potentially involved in this phenotype. Our results demonstrate for the first time the involvement of microRNA in normal mammary gland biology and have generated animal tools that will help the understanding of microRNA function and targets in this organ

Der volle Inhalt der QuelleMastectomy is one of the most common way to treat breast cancer, it consists in the removal of breast tissue to remove tumor cells. This surgical act causes a consequent loss of tissue and can then be followed by a breast reconstruction operation to fill in the missing volume. Implant based or autologous fat grafting (fat flap or lipofilling) are some of breast reconstruction method, however they all have advantages and drawbacks. Tissue engineering chamber (TEC) using fat flap from the patient’s own tissue could be a promising solution to restore large volume of mature and vascularized adipose tissue and a therapeutic alternative to current breast reconstruction techniques.The main objective of this thesis it to improve TEC by using additive manufacturing and bioabsorbable polymers. The use of bioresorbable thermoplastic polymers eliminates the need for a second surgery, which would consist of removing the implant after breast reconstruction. In addition, using 3D printing to manufacture the TEC will allow patients to be offered tailor-made implants adapted to their morphology and therefore improve the aesthetic aspect of the reconstruction.The study first focused on the choice of an additive manufacturing process and a sterilization method for the development of the implant to minimize the degradation of the selected biomaterials. Fused Filament Fabrication (FFF) as well as ethylene oxide sterilization were chosen as means of producing the final sterile device. An in vitro degradation study was then carried out to determine the resorption profiles of PLGA and PLCL. Finally, an in vivo study was carried out on a rat model which enabled us to validate the concept of 3D-printed bioabsorbable TEC. The two selected polymers were therefore shown to be compatible with the tissue engineering chamber reconstruction process and thus allowed the growth of the fat flap over time within the TEC
