The molecular mechanism which decides the fate of neural crest cells, to express at the right time and in the correct form of representation. Introduction: Neural crest cells consists a tendency to differentiate into astonishing array of adult structures. The control of differentiation is explained by two opposing hypothesis. One of them proposed that, all neural crest cells contains an equal developmental potential, and their migration and fate is totally depends upon the environmental signals. The second hypothesis suggests that premigratory crest cells are programmed for different developmental behaviour. The migration pathways are regulated by the complex array of guidance molecules both attractive and repulsive.
