Model for mouse melanoblast migration. Melanocytes differentiating from melanoblast cells in the body trunk arise via the dorsolateral migration route between the ectoderm and dermomyotome. Neurogenic populations differentiating from ventrally migrating neural crest cells. In addition, ventrally migrating neural crest cells give rise to numerous other lineages, whereas the dorsolateral pathway is restricted to melanoblasts only (see text). MSA migratory staging area
