Our review demonstrates that the whole embryo culture system establish
ed by New and his colleagues, in combination with beneficial fluoresce
nt dye cell-tracing techniques, has greatly contributed to many advanc
ements in the field of mammalian craniofacial embryology, especially w
ith regard to elucidating the developmental behavior of cephalic crest
cells. In addition, based on recent results, further combining whole
embryo culture with mandibular organ culture methods has allowed us to
trace cranial crest cells for a much longer developmental period, i.e
., presently up to the cap stage in odontogenesis.
