Question

3. Neural Crest Cells.

c. Describe how an ectodermal cell becomes a multipotent neural crest cell.

d. How do lineage tracing experiments demonstrate that a neural crest cell is multipotent?

PLEASE EXPLAIN IN AT LEAST 2 Paragraphs

Answer 1

c)Neural crest cells are a temporary group of cells unique to vertebrates that arise from the embryonic ectoderm germ layer and in turn give rise to a diverse cell lineage.
After fusion of the neural fold to create the neural tube, cells originally located in the neural plate border become neural crest cells For migration to begin, neural crest cells must undergo a process called delamination that involves a full or partial epithelial-mesenchymal transition (EMT).
