Center

  1. The center of the neural plate remains grounded allowing a U-shaped neural groove to form. (Web site)

Expression

  1. All the results show that a reduction in the level of Bmp activity leads to an increase in the expression of Msx genes in the neural plate border. (Web site)

Extension

  1. The midline (notochord and notoplate) patterns the cell motility underlying convergence and extension of the Xenopus neural plate. (Web site)

Dorsal Neural Tube

  1. The dorsal neural tube is patterned by BMPs from the epidermal ectoderm flanking the neural plate. (Web site)

Neural Folds

  1. As the neural plate develops, it becomes surrounded by neural folds, which eventually create the cylindrical neural tube. (Web site)

Edges

  1. The notochordal plate then serves as an anchor for the neural plate and pushes the two edges of the plate upwards while keeping the middle section anchored. (Web site)

Induction

  1. The current role of BMP in neural crest formation is associated with the induction of the neural plate. (Web site)

Process

  1. During this process, called neurulation, the midline ectoderm that contains these cells thickens into a distinct columnar epithelium called the neural plate.

Fertilization

  1. In the normal human embryo, the neural plate arises approximately 18 days after fertilization. (Web site)

Anteriorly

  1. Once the median groove was completed, cells changed direction and moved anteriorly to contribute to the anterior neural plate and head fold. (Web site)

Laterally

  1. From splanchnopleuric mesoderm tissue, the cardiogenic plate develops cranially and laterally to the neural plate. (Web site)

Neurons

  1. We demonstrate that ectopic Relax expression induces a persistent enlargement of the neural plate and converts presumptive epidermal cells into neurons.

Cns

  1. In the developing fetus, the CNS originates from the neural plate, a specialised region of the ectoderm, the most external of the three embryonic layers.

Differentiating

  1. It inhibits ectoderm from differentiating to neural plate tissue. (Web site)

Vertebrates

  1. Putative neural crest gene-regulatory network functioning at the neural plate border in vertebrates. (Web site)

Nervous System

  1. The neural plate will differentiate into all of the neurons and most of the supporting cells of the nervous system (neuroglial cells). (Web site)
  2. Neurulation Gastrulation is followed by neurulation, during which the primordium of nervous system, the neural plate is laid down. (Web site)

First

  1. First, ectopically expressed Relax, like Xash-3, causes the neural plate to expand laterally.
  2. Here we report that Lmx1a is first expressed at E8.5 in a small number of cells in the lateral neural plate. (Web site)

First Sign

  1. The first sign of the developing nervous system is the neural plate that can be seen at about the 16th day of development. (Web site)

Fetus

  1. Sometimes the folds of the neural plate fail to close properly, resulting in neural tube defects (such as spina bifida) in the fetus.

Gestation

  1. During the first 3 weeks of gestation, the human embryo's ectoderm forms a thickened strip called the neural plate. (Web site)
  2. The neural plate folds outwards during the third week of gestation to form the neural groove.

Anterior Part

  1. The cerebral cortex develops from the most anterior part of the neural plate, a specialized part of the embryonic ectoderm. (Web site)

Neural Crest

  1. Neural crest is first induced in the region of the neural plate border. (Web site)

Neural Tube

  1. The neural plate will develop into the neural tube which gives rise the CNS, comprised by the spinal cord and the brain.
  2. The sequence of stages from neural plate to neural tube and neural crest is known as neurulation. (Web site)
  3. Central to all of these models are their definitions of the longitudinal axis and the longitudinal organization of the neural plate and neural tube.

Blastopore

  1. The open neural plate on the dorsal side has formed by the time the blastopore closes. (Web site)

Neural Groove

  1. As induction proceeds the neural plate will start to invaginate, which creates the neural crest and the neural groove. (Web site)
  2. Over the next few days, a "trench" is formed in the neural plate - this creates a neural groove. (Web site)
  3. On day 18, the neural plate invaginates along the midline, forming the neural groove with the neural folds on either side.

Tube

  1. Within the forebrain, the expression of these genes, as well as that of Nkx-2.1 and BF-1, are in distinct longitudinal regions in the neural plate and tube.
  2. The lateral margins of the neural plate then fold inward, eventually transforming the neural plate into a tube.
  3. FIG. 1. Schemata illustrating the topological radial structure and relative dorsoventral (DV) dimensions of the neural plate and tube. (Web site)

Neural

  1. In severe cases, there is no sac at all, and neural tissue from the open neural plate lies on the dorsal surface of the fetus.

Overlying Ectoderm

  1. Signals sent from the notochord to the overlying ectoderm cause that region of notochord to become neural plate. (Web site)
  2. Through the release of special chemicals, the overlying ectoderm is induced to divide more rapidly, forming a thickened mass called the neural plate.

Mesoderm

  1. By day 19, the interaction of ectoderm and mesoderm produces the neural plate, a precursor of the central nervous system.
  2. The notochord (derived from the mesoderm) is the primary inducer of the neural plate.

Development

  1. Development The cerebral cortex develops from the neural plate, a specialised part of the embryonic ectoderm.
  2. If we went back any further, we’d see things that might influence neural crest formation secondarily, such as the development of the neural plate.
  3. During development, pineal precursors originate in two domains at the lateral edges of the neural plate [ 22 - 27].

Embryonic Development

  1. The neural plate and the notochord are formed during early embryonic development.

Thickening

  1. The neural plate appears on the 17th day of gestation as a thickening of the embryonic ectoderm over the notochord. (Web site)
  2. This is evidenced by a thickening of the ectoderm above the notochord, the neural plate.

Cells

  1. A concurrent proliferation of cells along the lateral margins of the neural plate produces thickened raised edges called neural folds. (Web site)
