Abstract
Background The prevention of myelomeningocele (MMC) and meningocele (MC) is a public health concern. A systematic review on economic factors associated with MMC and MC can help the policy makers to evaluate the cost-effectiveness of screening and treatment. To our knowledge, this is the first systematic review to provide up-to date pharmacoeconomic evidence of all economic studies present in literature on different aspects of MMC and MC. Methods We searched in the National Health Service Economic Evaluation Database (NHSEED), PubMed, Cost-effectiveness Analysis Registry (CEA Registry), Centre for Reviews and Dissemination (CRD), Health Technology Assessment Database (HTAD), Cochrane Library, and Econlit. The PRISMA guidelines were followed in the search and evaluation of literature. Only articles in English not limited by the year of publication that fulfilled the eligibility criteria were included in this systematic review. Results Nineteen papers were included in the study. The studies were very heterogeneous and reported a comparison of the costs between prenatal versus postnatal repair, the cost of fetoscopic approach versus open surgery, the cost of ventriculoperitoneal shunting (VPS) versus endoscopic third ventriculostomy (ETV), and ETV with choroid plexus cauterization (ETV/CPC), the cost of hospitalization, and the cost of diagnosis for MMC. Conclusion The results of this study can help in implementing new policies in different countries to assist MC and MMC patients with the cost of treatment and screening.

Abstract
The emergence of tissue form in multicellular organisms results from the complex interplay between genetics and physics. In both plants and animals, cells must act in concert to pattern their behaviors. Our understanding of the factors sculpting multicellular form has increased dramatically in the past few decades. From this work, common themes have emerged that connect plant and animal morphogenesis-an exciting connection that solidifies our understanding of the developmental basis of multicellular life. In this review, we will discuss the themes and the underlying principles that connect plant and animal morphogenesis, including the coordination of gene expression, signaling, growth, contraction, and mechanical and geometric feedback.

Abstract
The development of the vertebrate spinal cord involves the formation of the neural tube and the generation of multiple distinct cell types. The process starts during gastrulation, combining axial elongation with specification of neural cells and the formation of the neuroepithelium. Tissue movements produce the neural tube which is then exposed to signals that provide patterning information to neural progenitors. The intracellular response to these signals, via a gene regulatory network, governs the spatial and temporal differentiation of progenitors into specific cell types, facilitating the assembly of functional neuronal circuits. The interplay between the gene regulatory network, cell movement, and tissue mechanics generates the conserved neural tube pattern observed across species. In this review we offer an overview of the molecular and cellular processes governing the formation and patterning of the neural tube, highlighting how the remarkable complexity and precision of vertebrate nervous system arises. We argue that a multidisciplinary and multiscale understanding of the neural tube development, paired with the study of species-specific strategies, will be crucial to tackle the open questions.

Abstract
Neurulation transforms the neuroectoderm into the neural tube. This transformation relies on reorganising the configurational relationships between the orientations of intrinsic polarities of neighbouring cells. These orientational intercellular relationships are established, maintained, and modulated by orientational cell adhesions (OCAs). Here, using zebrafish (Danio rerio) neurulation as a major model, we propose a new perspective on how OCAs contribute to the parallel, antiparallel, and opposing intercellular relationships that underlie the neural plate-keel-rod-tube transformation, a stepwise process of cell aggregation followed by cord hollowing. We also discuss how OCAs in neurulation may be regulated by various adhesion molecules, including cadherins, Eph/Ephrins, Claudins, Occludins, Crumbs, Na+ /K+ -ATPase, and integrins. By comparing neurulation among species, we reveal that antiparallel OCAs represent a conserved mechanism for the fusion of the neural tube. Throughout, we highlight some outstanding questions regarding OCAs in neurulation. Answers to these questions will help us understand better the mechanisms of tubulogenesis of many tissues.

Abstract
Neural tube defects (NTDs) are among the most devastating and common congenital anomalies worldwide, and the ability to model these conditions in vivo is essential for identifying causative genetic and environmental factors. Although zebrafish are ideal for rapid candidate testing, their neural tubes develop primarily via a solid neural keel rather that the fold-and-fuse method employed by mammals, raising questions about their suitability as an NTD model. Here, we demonstrate that despite outward differences, zebrafish anterior neurulation closely resembles that of mammals. For the first time, we directly observe fusion of the bilateral neural folds to enclose a lumen in zebrafish embryos. The neural folds fuse by zippering between multiple distinct but contiguous closure sites. Embryos lacking vangl2, a core planar cell polarity and NTD risk gene, exhibit delayed neural fold fusion and abnormal neural groove formation, yielding distinct openings and midline bifurcations in the developing neural tube. These data provide direct evidence for fold-and-fuse neurulation in zebrafish and its disruption upon loss of an NTD risk gene, highlighting conservation of vertebrate neurulation and the utility of zebrafish for modeling NTDs.

Abstract
The human neocortex is undoubtedly considered a supreme accomplishment in mammalian evolution. It features a prenatally established six-layered structure which remains plastic to the myriad of changes throughout an organism’s lifetime. A fundamental feature of neocortical evolution and development is the abundance and diversity of the progenitor cell population and their neuronal and glial progeny. These evolutionary upgrades are partially enabled due to the progenitors’ higher proliferative capacity, compartmentalization of proliferative regions, and specification of neuronal temporal identities. The driving force of these processes may be explained by temporal molecular patterning, by which progenitors have intrinsic capacity to change their competence as neocortical neurogenesis proceeds. Thus, neurogenesis can be conceptualized along two timescales of progenitors’ capacity to (1) self-renew or differentiate into basal progenitors (BPs) or neurons or (2) specify their fate into distinct neuronal and glial subtypes which participate in the formation of six-layers. Neocortical development then proceeds through sequential phases of proliferation, differentiation, neuronal migration, and maturation. Temporal molecular patterning, therefore, relies on the precise regulation of spatiotemporal gene expression. An extensive transcriptional regulatory network is accompanied by post-transcriptional regulation that is frequently mediated by the regulatory interplay between RNA-binding proteins (RBPs). RBPs exhibit important roles in every step of mRNA life cycle in any system, from splicing, polyadenylation, editing, transport, stability, localization, to translation (protein synthesis). Here, we underscore the importance of RBP functions at multiple time-restricted steps of early neurogenesis, starting from the cell fate transition of transcriptionally primed cortical progenitors. A particular emphasis will be placed on RBPs with mostly conserved but also divergent evolutionary functions in neural progenitors across different species. RBPs, when considered in the context of the fascinating process of neocortical development, deserve to be main protagonists in the story of the evolution and development of the neocortex.

Abstract
The neural tube of amniotes is formed through different mechanisms that take place in the anterior and posterior regions and involve neural plate folding or mesenchymal condensation followed by its cavitation. Meanwhile, in teleost trunk region, the neural plate forms the neural keel, while the lumen develops later. However, the data on neurulation and other morphogenetic processes in the posterior body region in Teleostei remain fragmentary. We proposed that there could be variations in the morphogenetic processes, such as cell shape changes and cell rearrangements, in the posterior region compared to the anterior one at the different stages. Here, we performed morphological and histochemical analyses of morphogenetic processes with an emphasis on neurulation in the zebrafish tail bud (TB) and posterior region. To analyze the posterior expression of sox2 and tbxta we performed whole mount in situ hybridization. We showed that the TB cells of variable shapes and orientation are tightly packed, and the neural and notochord primordia develop first. The shape of the neural primordium undergoes numerous changes as a result of cell rearrangements leading to the development of the neural rod. At the prim-6 stage, the cells of the neural primordium directly form the neural rod. The neuroepithelial cells undergo sequential shape changes. At the stage of the neural rod formation, the apical regions of triangular neuroepithelial cells of the floor plate are enriched in F-actin. The neurocoel development onset is above the apical poles of neuroepithelial cells. The expression domains of sox2 and tbxta become more restricted during the development.
