The multiplication or reproduction of Schwann cells by cell division, resulting in the expansion of their population in response to an axonal lesion. The newly generated Schwann cells support subsequent axon regeneration in the peripheral nervous system.

The multiplication or reproduction of Schwann cells, resulting in the expansion of their population. Schwann cells are a type of glial cell in the peripheral nervous system.

The regrowth of axons outside the central nervous system (outside the brain and spinal cord) following an axonal injury.

Catalysis of the reaction: ATP + a protein = ADP + a phosphoprotein. This reaction requires diacylglycerol.

Calcium-dependent catalysis of the reaction: ATP + a protein = ADP + a phosphoprotein.

Catalysis of the reaction: ATP + a protein = ADP + a phosphoprotein. This reaction requires diacylglycerol but not calcium.

The formation of the notochord from the chordamesoderm. The notochord is composed of large cells packed within a firm connective tissue sheath and is found in all chordates at the ventral surface of the neural tube. In vertebrates, the notochord contributes to the vertebral column.

The formation of the specialized region of ectoderm between the neural ectoderm (neural plate) and non-neural ectoderm. The neural crest gives rise to the neural crest cells that migrate away from this region as neural tube formation procedes.

A transition where an epithelial cell loses apical/basolateral polarity, severs intercellular adhesive junctions, degrades basement membrane components and becomes a migratory mesenchymal cell.

The formation of a thickened region of the neurectoderm that is roughly triangular in cross section. The neural keel develops from the neural plate and develops into the neural rod. Neural keel formation occurs during primary neurulation in teleosts.

The process in which the neural plate is shaped by the intrinsic movement of the epidermal and neural plate regions.

The process in which the anatomical structures of an epithelial sheet are generated and organized. An epithelial sheet is a flat surface consisting of closely packed epithelial cells.

The formation of a solid rod of neurectoderm derived from the neural keel. The neural rod is roughly circular in cross section. Neural rod formation occurs during primary neurulation in teleosts.

The formation of the neural tube from an epithelial cell sheet (the neuroepithelium or neural plate). In primary neurulation, the cells surrounding the neural plate direct the neural plate cells to proliferate, invaginate, and pinch off from the surface to form a hollow epithelial tube. Primary neurulation is the typical mechanism of formation of the anterior neural tube.

The morphogenesis of an embryonic epithelium into a tube-shaped structure.
