in the ectomesenchymal-endodermal interaction system ( eeis ) , a hanging drop culture in which an explant of neural fold from behind the prospective ear region of a triturus alpestris neurula together with a piece of ventrolateral pharynx endoderm is cultivated , the differentiation of a variety of neural crest-derived cells ( nerve cells , pigment cells , cartilage cells , perichondrial cells , schwann cells ) can be followed .
