Description
Neural tube development (GO:0021915) is the biological process whose specific outcome is the progression of the neural tube over time, from its formation to the mature structure. The mature neural tube is segmented into the forebrain, midbrain, hindbrain and spinal cord regions, and neural crest cells have budded away from the epithelium. This process is foundational for central nervous system formation and is a major focus of developmental biology and congenital disease research. Researchers study neural tube development to understand how patterning signals, morphogenetic movements, and cell fate decisions are coordinated, and to identify the genetic and environmental causes of neural tube defects. Recent advances in organoid and microfluidic models have made it possible to reconstruct patterned human neural tube development in vitro, enabling mechanistic studies that were previously limited to animal models.

What Is GO:0021915?
GO:0021915 neural tube development is defined as the process whose specific outcome is the progression of the neural tube over time, from its formation to the mature structure. The mature structure of the neural tube exists when the tube has been segmented into the forebrain, midbrain, hindbrain and spinal cord regions, and neural crest has budded away from the epithelium. In practice, this term covers neural plate induction, neural fold elevation, neural tube closure, regional patterning along the anterior-posterior and dorsal-ventral axes, and the emergence of neural crest cells.
Why Is neural tube development Important in Cell Biology?
Neural tube development is important because it establishes the entire central nervous system and because its failure causes neural tube defects, which are among the most common and severe congenital malformations in humans. Understanding the cellular, molecular and biomechanical mechanisms of neural tube closure provides a basis for genetic counseling, prevention strategies, and the development of stem cell models for disease modeling and drug discovery.
• Neural tube development is the embryonic process that forms the brain and spinal cord.
• Neural tube closure defects cause spina bifida, anencephaly and related congenital malformations.
• Planar cell polarity signaling controls morphogenetic movements required for neural tube closure.
• Neural crest cells, which bud away from the neural tube, contribute to craniofacial structures and peripheral neurons.
• Human organoid and microfluidic models enable mechanistic studies of patterned neural tube development.
• Co-development of somites and neural tube can be modeled in human trunk-like structures.
• Genes such as IRF6 have specific requirements in neural crest and periderm during neural tube and craniofacial development.
• Understanding neural tube development informs prevention and screening strategies for neural tube defects.
What Happens During neural tube development?
Neural plate induction and neural fold formation
In simple terms: The flat sheet of cells that will become the nervous system forms and begins to fold.
Neural tube development begins with induction of the neural plate, a thickened ectodermal sheet that subsequently elevates to form neural folds. Signaling by BMP, WNT and FGF pathways patterns the neural plate and defines the neural versus non-neural ectoderm boundary. The neural folds then elevate and approach each other along the dorsal midline, a process that requires coordinated changes in cell shape and tissue mechanics.
Neural tube closure
In simple terms: The folded edges of the neural plate meet and fuse to create a closed tube.
Neural tube closure is a multi-step process involving apical constriction, cell intercalation, and convergent extension, which together bring the neural folds together and fuse them. Closure initiates at specific sites along the anterior-posterior axis and proceeds bidirectionally, with failure at any step resulting in neural tube defects. Planar cell polarity signaling is a key regulator of the morphogenetic movements that drive closure.
Anterior-posterior and dorsal-ventral patterning
In simple terms: The closed tube is divided into regions that will become the forebrain, midbrain, hindbrain and spinal cord.
After closure, the neural tube is patterned along the anterior-posterior axis into forebrain, midbrain, hindbrain and spinal cord regions, and along the dorsal-ventral axis by opposing SHH and BMP/WNT signals. This patterning establishes distinct progenitor domains that give rise to specific neuronal and glial subtypes. Early spinal cord development from neural tube formation to neurogenesis has been reviewed in detail.
Neural crest delamination
In simple terms: Some cells at the top of the tube break away to form migratory cells that build facial and peripheral structures.
Neural crest cells bud away from the dorsal neural tube epithelium and migrate to diverse destinations, contributing to craniofacial bone and cartilage, peripheral neurons, and melanocytes. Genes such as IRF6 have neural crest-specific and periderm-specific requirements during neural tube and craniofacial development. The budding of neural crest is a defining feature of the mature neural tube as described in GO:0021915.
Co-development with somites and trunk structures
In simple terms: The neural tube develops together with the adjacent somites that form the body wall and muscles.
Neural tube development occurs in coordination with somite formation and trunk morphogenesis, and this co-development can be modeled in human trunk-like structures. Microfluidic gradients have been used to generate patterned human neural tube models that recapitulate key aspects of neural tube development in vitro. These models enable studies of human-specific aspects of neural tube development and defects.

How Is neural tube development Regulated?
Neural tube development is regulated by a combination of secreted morphogens, planar cell polarity signaling, and mechanical forces. WNT/planar cell polarity signaling controls the morphogenetic movements of gastrulation and neural tube closure. BMP, WNT and FGF signals pattern the neural plate and neural tube along multiple axes. Apical constriction and actomyosin contractility are regulated by Rho-ROCK signaling and polarity proteins such as PARD3 and SCRIB. IRF6 has been shown to have neural crest and periderm-specific requirements during neural tube and craniofacial development.
neural tube development and Human Disease
| Gene | Disease / Biology | Potential Experimental Model |
|---|---|---|
| VANGL1 | Neural tube defects | Knockout or point mutation in human neural tube organoids |
| VANGL2 | Neural tube defects | Knockout mouse or human iPSC-derived neural tube models |
| IRF6 | Craniofacial and neural crest disorders | Neural crest-specific knockout in organoid models |
| SHH | Holoprosencephaly and neural tube patterning defects | Knockout or knock-in in neural tube organoids |
| TBXT | Trunk and somite-related developmental defects | Trunk-like structure models with neural tube |
Neural tube defects
Failure of neural tube closure causes neural tube defects such as spina bifida and anencephaly, which are among the most common congenital malformations. Genetic studies have identified variants in planar cell polarity genes, including VANGL1 and VANGL2, that are associated with neural tube defects. Environmental factors such as folate status also influence risk, and prevention strategies have been developed based on this understanding.
Craniofacial and neural crest disorders
Because neural crest cells bud away from the neural tube and contribute to craniofacial structures, defects in neural tube development can lead to craniofacial anomalies. IRF6 mutations are associated with craniofacial disorders, and its neural crest-specific requirements have been studied in neural tube and craniofacial development.
Spinal cord and neurodevelopmental disorders
Early spinal cord development from neural tube formation to neurogenesis is critical for motor and sensory function, and disruptions can contribute to neurodevelopmental disorders. Human organoid and microfluidic models of neural tube development provide platforms for studying these conditions.
