What is neural crest induction?
The induction of neural crest is a multistep process, starting at the early gastrula stage and continuing until neural tube closure. Neural crest induction can be monitored by the differentiation of pigment cells, which can be easily identified macroscopically, or by the expression of neural crest-specific genes.
How are neural crest cells induced?
The formation of the neural crest has been described as a classic example of embryonic induction, in which specific tissue interactions and the concerted action of signaling pathways converge to induce a multipotent population of neural crest precursor cells.
Do amphibians have a neural crest?
coqui is the only amphibian known in which it effectively labels migrating neural crest-cells. There are not enough comparative data to determine whether this feature is functionally associated with direct development or is instead unrelated to reproductive mode.
What are neural crest tumors?
pNTs are members of tumors derived from the neural crest cells. The neural crest cells are highly migratory and multipotent population that develop into many cell types and tissues throughout the body.
What happens to neural crest cells?
Neural crest cells (NCC) are multipotent cells induced at the border of the neural plate that subsequently migrate throughout the embryo and later differentiate into multiple cell types contributing to most of the peripheral nervous system and the cranio-facial cartilage and bones, as well as pigment and endocrine …
What is the neural crest cells?
Neural crest cells (NCCs) are a multipotent and migratory cell population in the developing embryo that contribute to the formation of a wide range of tissues. Defects in the development, differentiation and migration of NCCs give rise to a class of syndromes and diseases that are known as neurocristopathies.
What is the neural crest and what is its importance?
Early in the process of development, vertebrate embryos develop a fold on the neural plate where the neural and epidermal ectoderms meet, called the neural crest. The neural crest produces neural crest cells (NCCs), which become multiple different cell types and contribute to tissues and organs as an embryo develops.
What is Neural crest cells?
Where are neural crest cells found?
(A) Neural crest cells are generated at the neural plate border, the junction between the neural plate and surface ectoderm. Both the surface ectoderm through Wnt6 and the neural plate through BMPs can induce neural crest cell formation.
