Neural crest cell migration. Neural crest (NC) cells (blue) emerge from the dorsal neuroepithelium and migrate extensively throughout the embryo. The cephalic NC cells mainly migrate under the skin and toward the ventral portions of the face with some subpopulations migrating further ventrally toward the heart and along gut. The trunk NC cells mostly invade the ventral regions of the trunk and colonize the skin.
