Neural Crest
(Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2014-09-15)
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 ...
Neurocristopathies
(Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2014-09-19)
Neurocristopathies are a class of pathologies in vertebrates,
including humans, that result from abnormal expression, migration,
differentiation, or death of neural crest cells (NCCs) during embryonic development. NCCs are ...
