Culture of mouse embryos during neurulation

Development, 1981
ABSTRACT A comparison between static versus rotator culture systems and a variety of media (rat serum, new born calf serum, DMEM and Waymouth’s) was made in an attempt to promote in vitro growth of mouse embryos from the beginning of neurulation (headfold stage) to the closure of the neural tube and formation of the limb buds (48 h).

O3. Secondary neurulation: Another type of neurulation by mesenchymal-to-epithelial transition

Differentiation, 2010
Two different types of neurulation processes take place during early embryogenesis. One is a well known neurulation where a sheet of epithelial cells folds inward to form a tubular structure (primary neurulation). Another one, called secondary neurulation (SN), is seen in a posterior region of the body.

Mechanotransduction During Vertebrate Neurulation

2016
Vertebrate neural tube formation is a complex morphogenetic process, which involves hundreds of genes dynamically coordinating various behaviors in different cell populations of neural tissue. The challenge remains to determine the relative contributions of physical forces and biochemical signaling events to neural tube closure and accompanying cell ...

Role of Complex Carbohydrates and Neurulation

Pediatric Neurosurgery, 1985
Extracellular and cell-coat complex carbohydrates play a major role in critical cellular functions, e.g., cell recognition and cell-to-cell adherence, which are involved in neurulation. To date, available evidence suggests that neurulation is a combination of intercellular and extracellular biochemical and morphological events which are under the ...

Neurules: improving the performance of symbolic rules

Proceedings 11th International Conference on Tools with Artificial Intelligence, 2000
In this paper, we present a method for improving the performance of classical symbolic rules. This is achieved by introducing a type of hybrid rules, called neurules, which integrate neurocomputing into the symbolic framework of production rules. Neurules are produced by converting existing symbolic rules. Each neurule is considered as an adaline unit,

Microtubules, interkinetic nuclear migration and neurulation

Experientia, 1978
The hypotheses dealing with mechanisms of neurulation are reviewed briefly. The phenomenon of interkinetic nuclear migration is thought to be an important factor to be considered in the invagination of the neuroepithelium in the chick embryo. Evidence is presented that implicates cytoplasmic microtubules in this phenomenon.

Declarative modeling of a neurulation-like process

Biosystems, 2007
MGS is an experimental programming language dedicated to the modeling and the simulation of a special kind of discrete dy- namical systems. Dynamical systems with a dynamical structure (or (DS)(2)) arise when the state space is not fixed a priori but is jointly computed with the current state during the simulation.

Folate manages cell shape during neurulation

Science, 2017
Neurodevelopment During neurulation in vertebrate embryos, a topologically flat surface pinches off a tube to form the central nervous system. Deficiencies in folate can cause failure to close that tube, leading to birth defects such as spina bifida. Balashova et al.

Normal neurulation in mammals.

Ciba Foundation symposium, 1994
During mammalian neurulation regional differences are evident between the cranial region, in which neurulation is most complex, the trunk as far as the caudal neuropore and the secondary neurulation region of the caudal trunk plus tail. Differences among these three regions are characterized by specific patterns of morphogenesis and by specific ...

Influence of Mitotic Activity on Neurulation Movements

Nature, 1966
ACCORDING to the present view, the forces responsible for the closure of the neural tube reside in the neural plate itself. On this view, the disproportion between the surface area and the volume of the neural plate is the real mechanical cause of neurulation movements.
