Abstract:

The SmN protein is a component of small nuclear ribonucleoprotein particles and is closely related to the ubiquitous SmB and B' splicing proteins. It is expressed in a limited range of tissues and cell types, including several undifferentiated embryonal carcinoma cell lines and undifferentiated embryonic stem cells. The protein declines to undetectable levels when embryonal carcinoma or embryonic stem cells are induced to differentiate, producing primitive endoderm or parietal endoderm or yielding embryonal bodies. This decline is due to a corresponding decrease in the level of the SmN mRNA. The potential role of SmN in the regulation of alternative splicing in embryonic cell lines and early embryos is discussed.

Abstract:

Somatic embryogenesis (SE) is a developmental process in which somatic cells undergo dedifferentiation to become plant stem cells, and redifferentiation to become a whole embryo. SE is a prerequisite for molecular breeding and is an excellent platform to study cell development in the majority of plant species. However, the molecular mechanism involved in M. sativa somatic embryonic induction, embryonic and maturation is unclear. This study was designed to examine the differentially expressed genes (DEGs) and miRNA roles during somatic embryonic induction, embryonic and maturation. The cut cotyledon (ICE), non-embryogenic callus (NEC), embryogenic callus (EC) and cotyledon embryo (CE) were selected for transcriptome and small RNA sequencing. The results showed that 17,251 DEGs, and 177 known and 110 novel miRNAs families were involved in embryonic induction (ICE to NEC), embryonic (NEC to EC), and maturation (EC to CE). Expression patterns and functional classification analysis showed several novel genes and miRNAs involved in SE. Moreover, embryonic induction is an active process of molecular regulation, and hormonal signal transduction related to pathways involved in the whole SE. Finally, a miRNA–target interaction network was proposed during M. sativa SE. This study provides novel perspectives to comprehend the molecular mechanisms in M. sativa SE.

Abstract:

Embryonal rhabdomyosarcoma is one of the major defined histologic variants of rhabdomyosarcoma that is mainly reported in children. The histologic appearance of this neoplastic entity recapitulates normal myogenesis. The tumor cells variably exhibit the different cellular phases of myogenesis ranging from undifferentiated mesenchymal cells to elongated myoblasts, multinucleated myotubes and differentiated muscle fibers. The carefully orchestrated embryonic signaling pathways that are involved in myogenesis, conceivably also result in the genesis of rhabdomyosarcoma; albeit as a corollary to an imbalance. We have attempted to review the pathogenesis of embryonal rhabdomyosarcoma in an endeavor to understand better, how closely it is linked to normal myogenesis in terms of its molecular dynamics and histologic presentation.

Abstract:

Embryonic stem cells, derived from the inner cell mass of murine blastocysts, can be maintained in a totipotent state in vitro. In appropriate conditions embryonic stem cells have been shown to differentiate in vitro into various derivatives of all three primary germ layers. We describe in this paper conditions to induce differentiation of embryonic stem cells reliably and at high efficiency into adipocytes. A prerequisite is to treat early developing embryonic stem cell-derived embryoid bodies with retinoic acid for a precise period of time. Retinoic acid could not be substituted by adipogenic hormones nor by potent activators of peroxisome proliferator-activated receptors. Treatment with retinoic acid resulted in the subsequent appearance of large clusters of mature adipocytes in embryoid body outgrowths. Lipogenic and lipolytic activities as well as high level expression of adipocyte specific genes could be detected in these cultures. Analysis of expression of potential adipogenic genes, such as peroxisome proliferator-activated receptors gamma and delta and CCAAT/enhancer binding protein beta, during differentiation of retinoic acid-treated embryoid bodies has been performed. The temporal pattern of expression of genes encoding these nuclear factors resembled that found during mouse embryogenesis. The differentiation of embryonic stem cells into adipocytes will provide an invaluable model for the characterisation of the role of genes expressed during the adipocyte development programme and for the identification of new adipogenic regulatory genes.

Abstract:

Embryogenic callus was obtained from the leaf explants of jojoba (Simmondsia chinensis (Link) Schneider cultured on MS containing 0.5 mg/l NAA and 0.5 mg/l Kn. Growth of embryonic callus increased in 0.5 mg/l Kn + 6% sucrose. In order to improve oil content, the embryonic callus was exposed to different doses (5, 10 and 15 Kr) of gamma radiation. It was found that oil content of embryonic callus of jojoba increased 1.41% by exposing to 5 Kr gamma radiation. Also, size of oil bodies in embryonic callus irradiated with 5 Kr increased compared to control. Furthermore, production of the fatty acids was enhanced by gamma irradiation. The highest percentage of total fixed oil (1.41) was recorded in 5 Kr radiation. However, the highest content of total fatty acids (98.612) was obtained when embryonic callus were exposed to 10 Kr of gamma radiation.

Abstract:

The in vitro developmental potential of mouse blastocyst-derived embryonic stem cell lines has been investigated. From 3 to 8 days of suspension culture the cells form complex embryoid bodies with endoderm, basal lamina, mesoderm and ectoderm. Many are morphologically similar to embryos of the 6- to 8-day egg-cylinder stage. From 8 to 10 days of culture about half of the embryoid bodies expand into large cystic structures containing alphafoetoprotein and transferrin, thus being analagous to the visceral yolk sac of the postimplantation embryo. Approximately one third of the cystic embryoid bodies develop myocardium and when cultured in the presence of human cord serum, 30 % develop blood islands, thereby exhibiting a high level of organized development at a very high frequency. Furthermore, most embryonic stem cell lines observed exhibit similar characteristics. The in vitro developmental potential of embryonic stem cell lines and the consistency with which the cells express this potential are presented as aspects which open up new approaches to the investigation of embryogenesis.

Abstract:

Embryonic stem (ES) cells are cells derived from the early embryo that can be propagated indefinitely in the primitive undifferentiated state while remaining pluripotent; they share these properties with embryonic germ (EG) cells. Candidate ES and EG cell lines from the human blastocyst and embryonic gonad can differentiate into multiple types of somatic cell. The phenotype of the blastocyst-derived cell lines is very similar to that of monkey ES cells and pluripotent human embryonal carcinoma cells, but differs from that of mouse ES cells or the human germ-cell-derived stem cells. Although our understanding of the control of growth and differentiation of human ES cells is quite limited, it is clear that the development of these cell lines will have a widespread impact on biomedical research.

Abstract:

The formation of the embryonic vasculature is essential for life. The components driving this process are well conserved across vertebrate species. At the core of vascular development is the specification of endothelial precursor cells from nascent mesoderm. Transcription factors of the ETS family are important regulators of endothelial specification. In this document we characterize the role of the ETS transcription factors, ETV2, during embryonic vascular development.Expression analysis shows that Etv2 is highly expressed in hematopoietic and endothelial precursor cells in the Xenopus embryo. In gain-of-function experiments, ETV2 is sufficient to activate ectopic expression of vascular endothelial markers. In addition, ETV2 activated expression of hematopoietic genes representing the myeloid but not the erythroid lineage. Loss-of-function studies indicate that ETV2 is required for expression of all endothelial markers examined. However, knockdown of ETV2 has no detectable effects on expression of either myeloid or erythroid markers. This contrasts with studies in mouse and zebrafish where ETV2 is required for development of the myeloid lineage. Our studies confirm an essential role for ETV2 in endothelial development, but also reveal important differences in hematopoietic development between organisms.Although ETV2 is a pivotal molecule in development it remains unidentified in the chicken genome. We hypothesize that chicken Etv2 is expressed in the early Gallus embryo, and is necessary for endothelial specification consistent with its role in other species. To test this hypothesis we attempted to amplify Etv2 transcripts from Gallus embryos using degenerate PCR. Disappointingly this strategy did not reveal a putative Etv2 candidate. However, some important findings were uncovered, including the cloning of a previously uncharacterized Gallus ETS protein, SPDEF. Additionally the identification of an annotation error mis-identifying Ets gene "Erf" as "Etv3" (also an Ets gene) provided details on gene arrangement previously unknown. The workflow described could be used in future studies for the identification of other members of gene families that exhibit gaps, keeping in mind the goal of the study and the limitations of each technology.

Abstract:

Depuis la publication par Alan Turing de son article ‘The Chemical Basis of Morphogenesis” en 1952, une révolution moléculaire a eu lieu en biologie et les mathématiciens ont fourni un nombre croissant de cadres théoriques afin de modéliser des motifs observés dans la nature. Cette thèse a pour objectif d’unifier les récentes découvertes dans ces deux domaines en proposant un cadre théorique et des schémas de développement pour l’émergence des motifs cutanés aviaires par l’étude de la dynamique de formation du plumage dorsal. J'ai caractérisé l'apparition des primordiums de plumes dans le dos de plusieurs espèces d'oiseaux : poulets, cailles, faisans, diamants mandarins, émeus et manchots. Chez les quatre premières espèces, la peau est structurée de manière reproductible : de minces domaines de compétence longitudinaux, marqués par la bêta-caténine, déclenchent une vague de rangées formant des plumes qui se propagent latéralement. Le processus est très différent chez les émeus et manchots: les plumes s'individualisent dans des domaines compétents et apparaissent rapidement sur toute la peau, de manière régulière ou irrégulière. J'ai ensuite reproduit les attributs de cette dynamique avec un modèle unifié de réaction-diffusion-chimiotactisme, avec un terme de prolifération logistique. En ajustant les conditions initiales, ce modèle récapitule les différentes dynamiques de patterning observées, et prédit que la prolifération cellulaire contrôle la synchronisation du processus de configuration. Ce modèle étude ouvre des perspectives concernant l'évolution des motifs cutanés et discute les origines de propriétés de ces motifs tels que leur régularité et leur directionalité<br>Since Alan Turing’s milestone paper ‘The Chemical Basis of Morphogenesis” in 1952, a molecular revolution has taken place in biology and mathematicians have provided an increasing number of theoretical models that are able to generate many of the patterns observed in nature. This thesis aimed at unifying the extensive findings in both fields to propose theoretical frameworks and developmental schemes for the emergence of avian skin patterns, with a particular focus on dorsal plumage dynamics. I characterised the appearance of feather primordia in the dorsum of several bird species, namely chickens, quails, pheasants, zebra finches, emus and penguins. In the first four species, the patterning of the dorsal skin occurs in a highly reproducible manner: thin longitudinal domains of competence, marked by beta-catenin, trigger a wave of feather-forming rows that propagate laterally in a timely fashion, eventually forming feather tracts. In flightless emus and penguins, the process is much different: feathers first individualise within large competent domains, and later appear throughout the whole skin, in a quick and regular or irregular fashion. I then reproduced shared and varying attributes of these dynamics with a unified reaction-diffusion-chemotaxis model with logistic cell proliferation, which I used in a predictive way. It recapitulates all varying attributes of the patterning processes by tuning initial conditions, and predicts that cell proliferation controls the timing of the patterning process. Our framework opens up evolutionary perspectives, and the origins of pattern attributes such as regularity and directionality are discussed

Abstract:

Successful mammalian development to term requires that embryonic and extra-embryonic tissues communicate and grow in coordination, to form the body. After implanting into the uterus, the mouse embryo is comprised of three cell lineages: first, the embryonic epiblast (EPI) that forms the embryo proper, second, the extra-embryonic ectoderm (ExE) which contributes to the foetal portion of the placenta, and third, the visceral endoderm (VE) that contributes to the yolk sac. These three tissues form a characteristic ‘egg-cylinder’ structure, which allows signals to be exchanged between them and sets the stage for body axis establishment and subsequent tissue patterning. The mechanisms underlying this process are difficult to study in vivo because a different genetically manipulated mouse line must be generated to investigate each factor involved. This difficulty has prompted efforts to model mammalian embryogenesis in vitro, using cell lines, which are more amenable to genetic manipulation. The pluripotent state of the EPI can be captured in vitro as mammalian embryonic stem cells (ESCs). Although mouse ESCs have been shown to contribute to all adult tissues in chimeric embryos, they cannot undertake embryogenesis when allowed to differentiate in culture. Previous studies have shown that ESCs formed into three-dimensional (3D) aggregates, called embryoid bodies, can become patterned and express genes associated with early tissue differentiation. However, embryoid bodies cannot recapitulate embryonic architecture and therefore may not accurately reflect what happens in the embryo. In this study, a new technique was developed to model early mouse development which is more faithful to the embryo. ESCs were co-cultured with stem cells derived from the ExE, termed trophoblast stem cells (TSCs), embedded within extracellular matrix (ECM). These culture conditions lead to the self-assembly of embryo-like structures with similar architecture to the mouse egg cylinder. They were comprised of an embryonic compartment derived from ESCs abutting an extra-embryonic compartment derived from TSCs, and hence were named ‘ETS-embryos’. These structures developed a continuous cavity at their centre, which formed via a similar sequence of events to those that lead to pro-amniotic cavity formation in the mouse embryo, and required active Nodal/Activin signalling. After cavitation, ‘ETS-embryos’ developed regionalised mesodermal tissue and primordial germ cell-like cells originating at the boundary between embryonic and extra-embryonic compartments. Inhibitor studies revealed that this occurred in response to endogenous Wnt and BMP signalling, pathways which also govern these tissue specification events in the early mouse embryo. To demonstrate that ‘ETS-embryos’ were comparable to mouse embryos at the global transcriptional level, RNA-sequencing was then performed on different tissue regions of ‘ETS-embryos’ and the resulting transcriptomes were compared to datasets from mouse embryos. These data showed that ‘ETS-embryos’ were highly similar to mouse embryos at post-implantation stages in their overall gene expression patterns. Taken together, these results indicate that ‘ETS-embryos’ are an accurate in vitro model of mammalian embryogenesis, which can be used to complement studies undertaken in vivo to investigate early development.

Abstract:

Experiments were conducted to determine the currents involved in the pacemaker activity of aggregates and single cells from the embryonic chick heart. Two microelectrode voltage clamp studies of embryonic chick ventricular heart cell aggregates revealed two time-dependent current components in the pacemaker range of potentials ($-$60 to $-$120 mV). Barium (Ba, 5 mM) blocked the more negatively activated time-dependent component unmasking a component which remained inwardly directed for hyperpolarizing steps beyond the potassium equilibrium potential (E$ sb{ rm K}$). This component, which was blocked by cesium (Cs, 2 mM), is consistent with an inward current which activates upon hyperpolarization (the I, model) as proposed by DiFrancesco (1981a,b), for Purkinje fibers.<br>In order to minimize the problems associated with the accumulation/depletion of ions in the extracellular space during voltage clamp experiments, studies were carried out on single ventricular cells or small clusters of ventricular cells.

Abstract:

Neural progenitor cells (NPCs) in the embryonic nervous system generate a large number and variety of neurons in a process known as neurogenesis. NPCs reside in a regulatory ‘niche’ that provides an extensive array of diverse signals, and loss of any one of these signals can deplete the pool of NPCs and therefore impair neural development. These niche signals are most commonly studied in the forebrain, where a complex array of cell divisions yields a set of diverse NPCs. In contrast, little is known on the role of niche signals in regulating the behaviour of NPCs in the hindbrain, the evolutionary oldest part of the brain that is essential for many vital bodily functions. In the adult brain, blood vessels and the vascular growth factor VEGF-A regulate the behaviour of neural stem cells (NSC). However, it is not known whether either also regulates hindbrain neurogenesis. For my PhD research, I have used the mouse embryo hindbrain as a model to examine the role of blood vessels and VEGF-A receptors in developmental neurogenesis. My studies have revealed that NPCs divide most actively during a period of extensive blood vessel growth in the hindbrain, that hindbrain NPCs reside within a well-vascularised germinal zone (GZ) and that they make physical contact with the GZ vasculature. To establish whether VEGF-A receptors or hindbrain blood vessels regulate the behaviour of hindbrain NPCs, I have analysed mouse embryos lacking the neurovascular cell surface receptor NRP1 in either the neural or endothelial lineages. I found that NRP1 regulates the proliferative behaviour of hindbrain NPCs through its role in promoting GZ vascularisation, but not as a receptor for VEGF-A in NPCs. I have further shown that GZ vasculature sustains the size of the NPC pool through the period of hindbrain neurogenesis and may do so by limiting the expression of pro-differentiation signals to set the pace of neurogenesis. Even though blood vessels are best know for their role in tissue oxygenation, my results also show that NRP1-dependent GZ vasculature does not regulate hindbrain NPC behaviour through its role in oxygenating the neuroepithelium. In conclusion, my results identify an essential role for blood vessels in regulating NPC behaviour in the embryonic hindbrain and have increased our understanding of the regulatory niche that orchestrates developmental neurogenesis.

Abstract:

Branchial arches (BAs) are a series of transient structures that develop on the ventro-lateral surface of the head in vertebrate embryos. BAs initially appear as a series of similar segments; as development proceeds each BA will contribute to different structures. Here, it was investigated the transcriptional mechanisms that instruct the different fates of the BAs in development. Initially, each BA contains a blood vessel, known as aortic arch (AA) artery, that connects the dorsal aorta with the heart. Remodelling of the AAs is crucial to form the adult heart circulation. This process leads to regression of the anterior AAs, running though the first and second BAs (BA1 and BA2), and persistence of the AAs contained in more posterior BAs (PBA). To identify the mechanisms that control remodelling of the AAs, we compared the transcriptomes and epigenomic landscapes of different BAs. Using RNA-seq and H3K27Ac ChIP-seq, we uncovered the activation of a vascular smooth muscle cell (VSMC) differentiation transcriptional program exclusively in the PBAs (and not in BA1/BA2). In support of this finding, we show that VSMC differentiation occurs specifically in the PBAs, but not BA1-2 in mouse embryonic development. Despite the absence of VSMC differentiation in developing BA1-2, cells harvested from these tissues reveal a spontaneous tendency to differentiate towards VSMC fate when grown in vitro, and activate several VSMC-specific genes (Myocd, Acta2, Tagln, Jag1). Together, our results suggest that forming VSMCs is a key process for the persistence of AAs. We also showed that cells derived from all BAs have the potential to differentiate to VSMCs in vitro. However, only cells in the PBAs differentiate to VSMCs in vivo, resulting in the maintenance of posterior AAs. In this study, we also uncovered a novel transcriptional principle that specifies the fate of BA2. Using ChIP-seq, we found that binding of Meis transcription factors establish a ground pattern in the BAs. Hoxa2, which specifies BA2 identity, selects a subset of Meis-bound sites. Meis binding is strongly increased at these sites, which coincide with active enhancers, linked to genes highly expressed in the BA2 and regulated by Hoxa2. Thus, Hoxa2 modifies a ground state binding of Meis to instruct segment-specific transcriptional programs.

Abstract:

Embryonic stem cell derived cardiomyocytes are deemed an attractive treatment option for myocardial infarction. Their clinical efficacy, however, has not been unequivocally demonstrated. There is a need for better understanding and characterization of the cardiogenesis process. A microfluidic platform in vitro is used to dissect and better understand the differentiation process. Through this study, we find that while embryoid bodies (EBs) flatten out in a well plate system, differentiated EBs self-assemble into complex 3D structures. The beating regions of EBs are also different. Most beating areas are observed in a ring pattern on 2D well plates around the center, self-assembled beating large 3D aggregates are found in microfluidic devices. Furthermore, inspired by the natural mechanical environment of the heart, we applied uniaxial cyclic mechanical stretch to EBs. Results suggest that prolonged mechanical stimulation acts as a negative regulator of cardiogenesis. From this study, we conclude that the culture environments can influence differentiation of embryonic stem cells into cardiomycytes, and that the use of microfluidic systems can provide new insights into the differentiation process.

Abstract:

Head fold morphogenesis constitutes the first discernible epithelial folding event in the embryonic development of the chick. It arises at Hamburger and Hamilton (HH) stage 6 (approximately 24 hours into a 21-day incubation period) and establishes the anterior extent of the embryo [1]. At this stage, the embryonic blastoderm is composed of three germ layers (endoderm, mesoderm, and ectoderm), which are organized into a flat layered sheet that overlies the fibrous vitelline membrane (VM). Within this blastodermal sheet, a crescent-shaped head fold develops just anterior to the elongating notochord, spanning across the embryonic midline at the rostral end of neural plate. At the crest of this fold, the bilateral precardiac plates fuse in a cranial to caudal direction and give rise to the primitive heart tube and foregut [2, 3]. An understanding of head fold morphogenesis may thus offer insight into how embryonic tissues are arranged to make ready for proper cardiac formation.

Abstract:

We have examined the developmental changes in composition, amount, and uptake of yolk nutrients (fat, protein, water and carbohydrates) and the expression ofnutrient transporters in the yolk sac membrane (YSM) from embryonic day 11 (Ell) to 21 (E21) and small intestine from embryonic day 15 (E15) to E21 in embryos from young (22-25 wk) and old (45-50 wk) Cobb and Leghorn breeder flocks. The developmental expression profiles for the peptide transporter 1 (PepTl), the amino acid transporters, EAAT3, CAT-1 and BOAT, the sodium glucose transporter (SGLTl), the fructose transporter (GLUT5), the digestive enzymes aminopeptidase N (APN) and sucraseisomaltase (SI) were assayed by the absolute quantification real time PCR method in the YSM and embryonic intestine. Different temporal patterns of expression were observed for these genes. The effect of in ovo injection of peptides (the dipeptide Gly-Sar, purified peptides, trypsin hydrolysate) on transporter gene expression has been examined in the embryonic intestine. Injection of a partial protein hydrolysate resulted in an increase in expression of the peptide transporter PepT2. We have initiated a transcriptome analysis of genes expressed in the YSM at different developmental ages to better understand the function of the YSM.
