Neural crest cells are a unique group of cells that originate from the developing neural tube in embryos. They are multipotent, meaning they can differentiate into various cell types. These cells migrate throughout the body and contribute to the formation of diverse structures, including parts of the nervous system, facial bones, and pigment cells in the skin. During development, neural crest cells play a crucial role in forming the peripheral nervous system and other tissues. Their ability to move and transform is essential for proper embryonic development, and any disruptions in their migration can lead to congenital disorders, highlighting their importance in developmental biology.
