Placodes (depicted above), like neural crest cells, are multipotent cells unique to vertebrates. Placodes are ectodermal in origin and can either be neurogenic or non-neurogenic. Neurogenic placodes give rise to nervous or sensory cranial structures. Non-neurogenic placodes, such as epidermal placodes, give rise to hair follicles, teeth, and feathers.
