Hierarchical relationships between principal categories of neural crest cell-type derivatives based on a cladistic analysis of their characteristics, undertaken by Vickaryous and Hall(52). The analysis is based on a character matrix that encompasses aspects of cell phenotype, behaviour and labelling, and was subjected to both phenetic cluster analysis and cladistic parsimony analysis; only the results of the parsimony analysis are presented here. The hierarchy bears out the dichotomy between ectomesenchymal (e) and non-ectomesenchymal (n) fates.
