Embryonic and larval development of the endangered Chiapas killifish Tlaloc hildebrandi (Cyprinodontiformes: Profundulidae)

Journal of Fish Biology, EarlyView.
Abstract The early ontogeny of endemic freshwater fishes provides essential baseline biological information for conservation and management, particularly in species with restricted distributions and high vulnerability to habitat degradation, environmental change and population decline. This study presents the first detailed description of embryonic and

Role of Zic genes during neurulation. [PDF]

, 2005
Neurulation is the embryonic event that results in formation of the neural tube, the primordium of the central nervous system. Impairment of this process leads to neural tube defects (NTDs), which are among the commonest congenital malformations in ...

Junctional Neurulation: A Unique Developmental Program Shaping a Discrete Region of the Spinal Cord Highly Susceptible to Neural Tube Defects

, 2014
International audienceIn higher vertebrates, the primordium of the nervous system, the neural tube, is shaped along the rostrocaudal axis through two consecutive, radically different processes referred to as primary and secondary neurulation. Failures in

Dynamic acetylation profile during mammalian neurulation [PDF]

, 2019
BACKGROUND: Neural tube defects (NTDs) result from failure of neural tube closure during embryogenesis. These severe birth defects of the central nervous system include anencephaly and spina bifida, and affect 0.5-2 per 1,000 pregnancies worldwide in ...

Telencephalic Morphogenesis during the Process of Neurulation: An Experimental Study Using Quail–Chick Chimeras [PDF]

, 2008
After gastrulation, during the process of neurulation, the anterior neural region undergoes important morphological transformations. The almost flat epithelium of the rostral neural plate becomes transformed into a spherical region, the prosencephalic ...

Cilia in Nervous System Development, Function, and Disease

MedComm – Future Medicine, Volume 5, Issue 2, June 2026.
Cilia are evolutionarily conserved organelles that function as essential sensory and motility platforms in the nervous system. This review outlines key cilia‐dependent signaling pathways and their roles in neural development and function. Furthermore, it highlights how ciliary dysfunction can lead to a variety of neurological disorders, known as ...

Abnormal Enteric Nervous System Organization and Gastrointestinal Motility in Mice With Valproic Acid‐Induced Neural Tube Defects

Neurogastroenterology &Motility, Volume 38, Issue 6, June 2026.
Gastrointestinal tracts from fetuses with a valproic acid‐induced neural tube defect contain blood. Structurally, the enteric neuronal stripes are thinner with a narrower interstripe distance, leading to an increased number of stripes. Functionally, gastrointestinal motility is abnormal, with increased contraction frequency and increased length of ...

Rachipagus Parasitic Twin With Epithelialized Myelomeningocele in a Rural Ethiopian Neonate: A Case Report

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Rachipagus parasitic twinning is an exceptionally rare clinical entity resulting from an asymmetric monozygotic twinning process, characterized by a dorsally co‐joined partially formed twin. Co‐ existence of this condition with neural tube defect is uncommon, yet clinically significant.
