Nicole Le Douarin shares her research on the role of the neural crest in skeletal development. The Q/C (quail/chick) marker system revealed that apart from the peripheral nervous system (PNS), the melanocytes and some endocrine tissues, the NC plays a major role in the construction of the vertebrate head.
