Abstract:
Permeability involves the passage of fluids, ions, molecules, particulate matter and bacteria into and through a substance or tissue under different and varying conditions. The permeability of the dentin is essential to support the physiology and reaction patterns of the pulp-dentin organ. Nutrients and impulses are transported from the pulp via the odontoblast process and the contents of its tubules maintain the dentin as a vital tissue. However, the main interest of this paper focuses on penetration from the outside towards the pulp rather than from the pulp towards the outside. The present overview centers on the dentinal tubules; how they are formed and how they change as a result of normal and abnormal function, age, and pathological processes and the effect of these processes on the permeability of dentin. Particular attention is focused on the patency of the dentinal tubules.This overview is largely based on the author’s own research, clinical insights and active participation in continuing dental education over the last 50 years. It is not a review of the literature related to the permeability of dentin. Rather it presents interpretation of results related to the permeability of dentin based on experience and opinions acquired over a lifetime in dental research.

Abstract:
Insight into the interrelation between the structure and mechanical properties of dentin of a tooth is crucial for prevention and treatment of oral cavity diseases. The study of the structure of dental dentin is important for understanding the pathogenetic mechanisms of the spread of cariogenic microflora in progressive dental caries to the pulp and periodontium, as well as for the interpretation of the results of studies of dental dentin-adhesive materials. The in vitro research presented here involved the examination of coronal dentin in 46 intact teeth from rats, cats, dogs, and humans at various distances from the pulp chamber, with a focus on the quantity and diameter of dentinal tubules. The calculations were based on the analysis of 155 scanning electron microscope photographs of the enamel surface and pulp chamber wall. The researchers calculated the quantity and diameter of dentinal tubules per unit area, which they measured at various distances from the pulp chamber. It was found that dentinal tubules are the widest near the pulp chamber wall, where the average diameter ranged from 1.7 to 2.8 µm. The highest values were found in premolars of young humans and the lowest - in the incisors of rats. In the middle portion of the dentin, the diameter of dentinal tubules ranged from 1.0 to 13.3 µm, while at the periphery, it was 0.6–0.9 µm. The highest density of dentinal tubules per unit area was found closest to the pulp horn, and the lowest was in the enamel region. Near the pulp chamber wall, the average density of dentinal tubules ranged from 50 000 to 90 000/mm², in the middle of the dentin, it ranged from 37 000 to 50 000/mm², and at the periphery, it ranged from 10 000 to 25 000/mm². All examined teeth exhibited straight dentinal tubules, except for the rats’ incisors, which showed local irregularities. A comparison was made based on the quantity and width of dentinal tubules in the examined animals and humans.

Abstract:
AbstractElemental distribution maps by wavelength-dispersive electron microprobe of enamel and dentine in modern crocodile teeth illustrate variations in both minor and major elements. Mg has the largest difference between the enamel and dentine, being enriched in the dentine. Mg, Ca and P are not homogeneously distributed in the dentine, but their distribution reflects changes during growth of the teeth. These variations in compositional differences of teeth from modern samples potentially can assist in establishing growth rates in fossil teeth samples, and thereby provide information on the physiology of extant species.

Abstract:
Odontoblasts, the main cell type in teeth pulp tissue, are not cultivable and they are responsible for the first line of response after dental restauration. Studies on dental materials cytotoxicity and odontoblast cells physiology require large quantity of homogenous cells retaining most of the phenotype characteristics. Odontoblast-like cells (OLC) were differentiated from human dental pulp stem cells using differentiation medium (containing TGF-β1), and OLC expanded after trypsinization (EXP-21) were evaluated and compared. Despite a slower cell growth curve, EXP-21 cells express similarly the odontoblast markers dentinal sialophosphoprotein and dentin matrix protein-1 concomitantly with RUNX2 transcripts and low alkaline phosphatase activity as expected. Both OLC and EXP-21 cells showed similar mineral deposition activity evidenced by alizarin red and von Kossa staining. These results pointed out minor changes in phenotype of subcultured EXP-21 regarding the primarily differentiated OLC, making the subcultivation of these cells a useful strategy to obtain odontoblasts for biocompatibility or cell physiology studies in dentistry.

Abstract:
Objectives: The aim of the study was to evaluate the clinical success of mineral trioxide aggregate (MTA) partial pulpotomy as a definitive procedure in deeply carious permanent posterior teeth using 0.12% chlorhexidine (CHX) gluconate or normal saline as hemostatic agents. Materials and Methods: A pilot randomized control clinical trial was conducted on subjects with a deep carious lesion on 20 immature posterior teeth of subjects (10.8 ± 2.62 years). Caries and the superficial layer of exposed pulp were removed and then flushed with 0.12% CHX or saline solution. Gray MTA was placed, followed by resin-modified glass ionomer and composite. Results: 12 months follow-up showed 100% clinical and 90% radiographical success in both groups. Dentine Bridge was formed 90% in both the study and control group, which showed MTA partial pulpotomy is an effective procedure (P = 0.000). Conclusion: MTA partial pulpotomy using 0.12% CHX gluconate as a hemostatic agent for the treatment of deeply carious immature permanent posterior teeth appears to increase the radiographic rate of formation of dentin bridge as compared to the normal saline.

Abstract:
Les gènes du développement ont d'abord été mis en évidence chez la drosophile en 1950 (gène HOM), puis chez la souris en 1970 (gènes Hox). Ces gènes codent pour la mise en place de « champs », puis de populations cellulaires, puis de « systèmes composites ». Au cours de l'évolution, le cerveau et les cellules des crêtes neurales sont responsables, par l'intermédiaire de ces gènes et de leurs protéines du développement des divers systèmes composites du crâne et de la face et de leurs fonctions. Nous isolerons le système dentaire, le système musculaire, avec le système squelettique comme soutien avant intégration. Par des exemples cliniques différents nous proposerons une analyse génétique et fonctionnelle.

Abstract:
Objectives: To determine serum PTH and serum calcium levels among children with delayed eruption of permanent teeth, attending the dental OPD at LUMHS. Methodology: A cross-sectional study was conducted with the assistance of the Physiology Department, LUMHS, in collaboration with the Clinical Ward, Pediatric and Dental Wards, and D-R Lab, LUMHS, from March to August 2022. Children up to 18 years old, corresponding to the period of active odontogenesis and growth, diagnosed with odontogenesis stunting characterized by delayed or disrupted tooth development, as confirmed by clinical examination and radiographic imaging, visiting the dental outpatient department (OPD) were included. Blood samples for PTH and serum calcium levels were obtained with the informed consent of parents. Parathyroid Hormone was considered normal from 10 to 55 picograms/ml. Results: A total of 250 children were studied, with an overall mean age of 12.24 ± 12.0 years. Males comprised 60.4%, and females were 39.6%. Most cases (28.4%) had dentine score 0, 24.8% had dentine score I, 24.8% had dentine score II, 18.8% had dentine score IV, while only 3.2% had dentine score II. Mean parathyroid hormone levels were significantly associated with higher dentine scores (p < 0.05). Although mean parathyroid hormone levels were statistically insignificant according to children's age (p < 0.05). Conclusion: A decrease in levels of parathyroid hormones and calcium has been observed to contribute to the delay in the eruption of primary teeth. Additionally, factors such as stunted growth and deficiencies in parathyroid hormones and calcium levels further exacerbate this delay, highlighting the importance of adequate nutrition in dental development.

Abstract:
Introduction : en médecine légale, l'identification des restes humains est un problème récurrent. L'estimation de l'âge au décès est l'un des critères à évaluer. Chez les adultes, la hauteur de la transparence de la dentine radiculaire est utilisée. Cependant, dans le matériel archéologique, ce phénomène apparaît inconstant et en lien avec des modifications d'aspect de la dentine sclérotique. Le but de ce travail était d'observer les modifications de la dentine sclérotique à différents délais post-mortem en se concentrant sur la partie minérale qui est le composant principal de ce tissu et qui est susceptible d'avoir des variations plus marquées sur des délais post-mortem longs. Matériel et Méthode : l'étude comprenait deux parties (rétrospective et prospective) avec 21 dents humaines monoradiculées, trois datées du 18ème siècle provenant de fouilles archéologiques et dix-huit issues de dons du corps à la science de la Faculté de médecine de l'Université de Lille conservées dans des conditions équivalentes et analysées à différents délais post-mortem de 0, 1, 2 et 5 ans. Après inclusion en résine, les dents ont été sectionnées et polies, puis analysées au microscope électronique à balayage, complétés par une analyse semi-quantitative du calcium et du phosphore par microanalyse EDS-X, ainsi qu'une détection large d'éléments du tableau périodique. Dans un second temps nous avons réalisé une analyse cristallographique par diffractométrie en rayons X.Résultats : les analyses ont montré l'existence de modifications tubulaires, chimiques et cristallographiques de la dentine sclérotique en fonction du délai post-mortem. Notre étude au microscope électronique à balayage nous a permis d'observer une différence d'aspect des tubules en lien avec l'augmentation du délai post-mortem : perte du col péritubulaire et obstruction de la lumière des tubules par un matériau hyperdense. La microanalyse a mis en évidence des variations des rapports phosphocalciques entre les différents groupes, notamment au niveau de la jonction avec le cément et plus spécifiquement dans la canine qui pourrait être un bon modèle prédictif pour l'évaluation du délai post-mortem. Par diffractométrie, nous avons confirmé que la phase minérale de la dentine sclérotique, quel que soit le délai post mortem, était composée de cristaux d'hydroxyapatite, avec un meilleur niveau de cristallinité dans les dents archéologiques par rapport aux dents de délai post-mortem 5 ans, mais aussi entre les dents de délai post-mortem de 0 et 1 an, par rapport à 2 ans. Discussion : les différences observées pourraient reposer sur des modifications post-mortem de la phase minérale de la dentine sclérotique par des phénomènes de déminéralisation et reminéralisation, à l'origine d'une variation de la taille des cristaux d'hydroxyapatite situés dans la zone intra tubulaire et par la substitution du calcium par d'autres éléments, sous l'influence d'une action chimique et/ou bactérienne et donc une influence de l'environnement de la dent (buccal et extérieur). Ce travail nécessite d'être poursuivi, d'une part par l'utilisation de techniques d'imagerie permettant l'association d'une étude structurale, chimique et cristallographique comme la microscopie électronique à transmission, mais également par l'étude des modifications du collagène et des protéines non collagéniques rendant plus accessible les composants minéraux aux facteurs extérieurs. Il serait également pertinent de réaliser les analyses sur des dents d'intervalles post-mortem de dizaines d'années
Introduction: in forensics fields, the identification of human remains is a recurrent problem. Estimating age at death is one of the criteria to be evaluated. In adults, the height of root dentin transparency is used. However, in archaeological material, this phenomenon appears to be inconsistent and related to changes in the appearance of sclerotic dentine. The aim of this study was to observe the changes in sclerotic dentin at different post-mortem intervals, focusing on the mineral part, which is the main component of this tissue and is likely to have more marked variations over longer post-mortem periods.Material and Method: The study included two parts (retrospective and prospective) with 21 monoradicular human teeth, three dating frome the 18th century from archaeological excavations and eighteen from donations of the body to science from the Faculty of Medicine of the University of Lille preserved in equivalent conditions and analyzed at different post-mortem intervals of 0, 1, 2 and 5 years. After resin embedding, the teeth were sectioned and polished, then analyzed by scanning electron microscope, completed by semi-quantitative analysis of calcium and phosphorus using EDS-X microanalysis, as well as broad detection of elements from the periodic table. We then carried out a crystallographic analysis using X-ray diffractometry.Results: The analysis showed the existence of tubular, chemical and crystallographic changes in the sclerotic dentin as a function of the post-mortem interval. Our scanning electron microscope study revealed a difference in the appearance of the tubules linked to an increase post-mortem interval: loss of the peritubular collar and obstruction of the tubule lumen by a hyperdense material. Microanalysis highlighted variations in phosphocalcic ratios among the different groups, notably at the cementum junction and more specifically in the canine, which could be a good predictive model for assessing post-mortem interval. Using diffractometry, we confirmed that the mineral phase of sclerotic dentin, whatever the post-mortem interval, was composed of hydroxyapatite crystals, with a better level of crystallinity in archaeological teeth compared with teeth with a 5-year post-mortem interval, but also between teeth with a 0 and 1 year post-mortem interval, compared with 2 years. Discussion: the differences observed could be due to post-mortem changes of the mineral phase of sclerotic dentin through demineralization and remineralization phenomena, resulting in variations in the size of hydroxyapatite crystals located in the intra-tubular zone and through the substitution of calcium by other elements, under the influence of chemical and/or bacterial action and therefore an influence of the tooth's environment (buccal and external). This work needs to be pursued, on the one hand by using imaging techniques that combine structural, chemical and crystallographic studies, such as transmission electron microscopy, and on the other hand by studying changes in collagen and non-collagenous proteins making mineral components more accessible to external factors. It would also be relevant to carry out analyses on teeth from post-mortem intervals of decades

La structure tubulaire du tissu dentinaire permet de le considerer comme une structure poreuse. Le but de ce travail est d'essayer d'analyser in vitro et in situ, dans un premier temps les facteurs conditionnant la permeabilite de la dentine radiculaire, puis dans un deuxieme temps, les correlations entre l'etat de surface endocanalaire et les variations de permeabilite induites par diverses techniques de preparation endodontiques. La premiere partie comprend deux temps: une etude de la diffusion transdentinaire de solutions colorantes, puis de la permeabilite dentinaire en terme de filtration de fluide, ceci in vitro et in situ. La deuxieme partie est consacree a la mise au point d'une methode d'analyse de cliches de microscopie electronique a balayage par un systeme de traitement et d'analyse d'image permettant la mesure des surfaces recouvertes de boues dentinaires ou de debris organiques. La troisieme partie est consacree a l'etude des variations de permeabilite induites par quatre methodes de preparation endodontiques. L'aspect de la paroi endocanalaire dentinaire evalue par le systeme precedemment decrit est rapproche de ces variations de permeabilite

Abstract:
L’activation du système complément, qui se produit à la suite d’une infection ou d’un trauma, génère de puissants signaux moléculaires capables d’initier la réaction inflammatoire. Parmi ces signaux, le fragment actif C5a permet de recruter sur le site lésé les cellules qui expriment son récepteur (le C5aR/CD88). Bien que le C5aR/CD88 soit initialement connu pour être exprimé par les cellules inflammatoires, il est établi que de nombreuses cellules non immunitaires expriment ce récepteur indiquant son implication dans d’autres processus. Nos résultats ont permis de démontrer que l’activation du système du complément au niveau de la pulpe dentaire est réalisée non seulement à partir des protéines plasmatiques mais aussi des protéines synthétisées par les fibroblastes pulpaires. Ainsi, l’activation locale du système du complément, produit à la suite d’une infection, d’un trauma ou de l’application de biomatériaux, génère du C5a qui induit la migration des cellules progénitrices. Ce travail démontre pour la toute première fois l’implication du fragment actif C5a dans le recrutement de progénitrices pulpaires, étape clef au processus de régénération pulpo-Dentinaire. Ces travaux pourraient donc constituer une piste sérieuse dans l’établissement de nouvelles thérapies permettant de cibler les cellules progénitrices au cours du processus de régénération
After tissue injury or infection, Complement activation provides powerful signals initiating the inflammatory reaction. These events are mediated by biologically active fragments such as C5a which attracts cells expressing its receptor (C5aR/CD88) to the injury site. Besides inflammatory cells as the main C5aR-Expressing cells, various tissue cells have been reported to express this receptor suggesting its involvement in other processes. In order to investigate the possible relationship between complement activation and pulp regeneration, we investigated Complement activation in the dental pulp and progenitor cell migration from their perivascular niches to the pulp injury site to initiate the regeneration process.Our results indicate that complement activation in the dental pulp is the result of both plasma and fibroblast secreted complement proteins. Thus upon local complement activation, which can occur after pathological injury or biomaterials application, C5a induces pulp progenitors’ migration which is critical in initiating the regenerative processes. To our knowledge, this is the first work to demonstrate the involvement of C5a biologically active fragment in the recruitment human pulp progenitor cells. This may provide a useful future therapeutic tool in targeting the progenitor cells in a dentin/pulp regeneration process

Abstract:
Therapies to promote pulp repair and regeneration after injury should be underpinned by a deep understanding of normal tissue behaviour, and cellular signalling mechanisms. The objectives of this work were to understand normal structure of the tooth and to identify changes in its cellular elements and their complex interactions in response to dentine exposure. Revisiting pulp structure and function with a range of contemporary techniques may formalize observations into new concepts of tooth physiology and pathophysiology, and reveal new opportunities for therapeutic intervention. Studies within this thesis employed rodent mandibular incisors and molars with structural and functional investigations on demineralised teeth, non-demineralised freshly extracted pulp tissues and tissue explants. Observations were made on ground sections, haematoxylin-eosin stained sections, immunohistochemically-stained sections, and on quantitative reverse transcription polymerase chain reaction (q-RT-PCR) examination of tissue explants. Complex cellular structure and heterogeneity was observed within odontoblast and subodontoblast cellular populations. Previously undescribed odontoblast processes were identified within the predentine region during crown development and in the radicular pulp after tooth development. Programmed retraction of odontoblast processes was observed after dentine exposure by cavity preparation or tooth wear. Two phases of reactionary dentine deposition (atubular followed by tubular) was identified after tooth wear. This revealed a programmed cellular defensive mechanism which lead to tissue recovery and regeneration. This process could be controlled by autocrine or paracrine signalling mechanisms, as indicated by the presence of NGF and NGFR, in addition to a complex network of CGRP-IR axons. Observations suggested revision of established hypotheses including the hydrodynamic theory of dentine sensitivity and the role of extracellular pH in biomineralisation. This hypothesis could provide coherent explanation for several well-known dental mysteries including pulp stone development, dentine sclerosis and the mode of action of high pH materials (calcium hydroxide, and hydraulic calcium silicate cements) in the repair of pulp wounds.

Abstract:
Ce travail porte sur l'etude de l'arcade dentaire chez de jeunes adultes. Il comporte deux parties: la premiere, conventionnelle, situe l'arcade dentaire dans son environnement anatomo-physiologique en rappelant son origine phylogenique, embryologique et les facteurs influencant son developpement. La seconde decrit le protocole experimental et les resultats obtenus. Menee sur 90 etudiants inscrits en deuxieme annee de chirurgie dentaire, elle a porte d'une part, sur la modelisation individualisee de la forme d'arcade, et d'autre part, sur la recherche de correlations de ces formes avec des parametres dento-maxillo-faciaux classiques. A partir d'une empreinte aux alginates de l'arcade inferieure, certains points ont ete choisis afin de reproduire la courbe sur laquelle se positionnent les dents: le bord libre des incisives, la pointe canine, et les cuspides vestibulaires des premolaires et molaires, dents de sagesse exclues. L'enregistrement des coordonnees est realise par ordinateur a partir d'une camera ccd (charge coupled device) et les donnees ainsi recueillies sont ensuite traitees par le logiciel s-plus. Ces donnees permettent de modeliser de facon individualisee l'arcade enregistree. Nous presentons les principales methodes decrites dans la litterature. Il apparait que celles-ci sont sensibles a l'influence des dents en malposition. Nous proposons ensuite des methodes qui semblent etre plus appropriees aux problemes particuliers des orthodontistes: les ajustements robustes. L'analyse statistique de chaque arcade permet de calculer un coefficient caracteristique de forme. Cet indice est compare aux indices classiquement utilises en morphologie dento-faciale

Abstract:
Pendant des années, l'amélogenine, l'améloblastine et l'énaméline ont été considérées comme exclusives de l'émail dentaire, à la fois structurales et régulant la biominéralisation de ce tissu. Dans ce mémoire, nous avons étudié l'expression de ces trois protéines et leurs transcripts grâce à des analyses descriptives et quantitatives dans différents tissus, en prenant comme repère l'organe de l'émail. Nous avons également établi le patron ontogénique de l'expression de ces molécules avec l'étude de souris sauvages et de mutants nuls pour l'amélogénine à différents stades de dévelopmment. Ces données nous ont permis de confirmer l'expression extra-dentaire de ces molécules. Compte tenu de leur état chimique, leur distribution et leur quantité, nous proposons ces « proteines associées à l'émail » comme des protéines à double rôle ; d'un côté un rôle structural et de l'autre des fonctions de type facteur de croissance dans une voie physiologique intégrée. Ainsi, ces protéines participeraient également à la régulation du métabolisme du complexe alvéolo-dentaire. Enfin, l'ensemble de nos données suggèrent que les différents tissus osseux du squelette peuvent être caractérisés par le profil d'expression de ces protéines, lesquelles pourraient représenter des marqueurs spécifiques des structures osseuses d'origine neuroectodermique
For years, amelogenin, ameloblastin and enamelin have been considered as exclusive of the dental enamel, both structural and regulating biomineralization of this tissue. This work investigates these three proteins and their transcripts through descriptive and quantitative analyses in different hard and soft tissues taking as reference the enamel organ. We establish the ontogenetic pattern bf expression of these molecules using control and amelogenin knock-out mice of different ages. We confirm the expression of these molecules in non-dental tissues. Given their chemical state, their distribution and quantity, we suggest these " enamel related proteins" as proteins with a double rote: a structural rote in enamel but also as signaling molecute, with growth factor-like functions. They would indeed participate in the regulation of the metabolism of dentoatveotar complex. Additionaly, our data suggest that the various skeletal tissues can be characterized by the expression profile of these proteins, which may represent specific markers of neural-crest derived bones

In the manual the considerable attention is paid to consideration of questions of an etiology, mechanisms of development of pathological processes and their manifestations in maxillofacial area. Are in detail lit not only widespread pathology forms in stomatologic practice, but also and those general pathological processes which are followed by the expressed manifestations in a mouth. The manual is designed for students of stomatologic faculties of medical schools; it will also be useful to all who is interested in pathophysiology problems. Lectures of department of pathological physiology of SEI VPO Saratovskogo of the state medical university of V. I. Razumovsky by it for students stomatologists are the basis for a grant. The main objective of this course of lectures – the message to students of a certain volume of the knowledge reflecting a current state of world pathophysiological science who can be useful in daily practical activities of the dentist.

Abstract:
Children are in a state of delicate physiologic equilibrium and, unlike adults, are more susceptible to medications and their adverse effects. Medicines used for children should be carefully selected, and the minimum dose required should be administered. Possible adverse reaction in multidrug therapy is also essential. The pediatric dentist must also consider any other drug the child may be taking while prescribing drugs and understanding children’s presenting signs and symptoms.

Abstract:
Adding modern technology to clinical diagnostic methods instead of replacing them, represents an improvement in patient care, because objective bio-physiologic measurements enhance the information obtained from the patient report of symptoms and the clinical observations made during a patient examination. Combining multiple tests has universally been acknowledged to enhance diagnostic sensitivity and specificity. The increased objectivity of bio-physiologic measurements that represent quantifiable data for diagnostic purposes also adds value to treatment monitoring and/or outcome assessments. The most recent evidence suggests that the emotional aspects of temporomandibular disorders (TMD), are more the result of pain and dysfunction than the cause. This chapter discusses several dental technologies that are now available that provide objective bio-physiologic measurements of masticatory functions. Bio-physiologic measurements have the capacity to provide detailed, objective analysis. Each diagnostic technology is illustrated with an example of its output data, recorded from both an asymptomatic subject, as well as a patient with masticatory dysfunction. Of significance when considering employing these instruments is that a dentist can use these technologies to improve the initial diagnostic accuracy, and also to verify the degree of success after rendered treatment. Finally, recommendations are provided that dental medicine should accept the use of modern digital technology as an indispensable part of modern clinical practice, and that resistance to its implementation should no longer inhibit its widespread clinical use.

Abstract:
Dental treatment has been associated with pain by adults and children alike. The fear associated with the perceived pain causes a lot of anxiety and is a common cause for patients to show avoidance towards basic dental care. A painless experience during dental treatment allows children to look forward to future dental appointments and allows the dentist to establish a good rapport with the child. Various agents are available for the administration of local anesthesia with lignocaine being the most common agent. As children have unique physiology and anatomic variations, the techniques for local anesthesia require minor modifications. Advances in local anesthesia materials and techniques have provided the dental surgeon to accomplish the goal of true painless dentistry.

Abstract:
Evidence reports the key roles of lncRNAs in several regulatory mechanisms of neurons and other brain cells. Neuronal lncRNAs are crucial for NSCs mediated-neuronal developmental stages like neurogenesis, neuronal differentiation, and synaptogenesis. Moreover, multilineage properties of NSCs and their association to specific cell types render them to identify the commonly accepted biomarkers for the brain. It is important to delineate the correlation between lncRNAs and NSCs fate decisions during neuronal development stages. In this review, we will summarize how NSCs fabricate embryonic tissue architecture of the central nervous system (CNS) and act as residuum in subventricular zone (SVZ) nearby the lateral wall of the lateral ventricles and the subgranular zone (SGZ) of hippocampus dentate gyrus (DG) of the adult brain. Additionally, describe the roles and molecular mechanisms of lncRNAs involved in NSCs self-renewal, neurogenesis, gliogenesis and synaptogenesis over the course of neural development. This will help us to better understand neuronal physiology.
