WebDuring embryological development, the final structures formed from neural crest cells are termed neural crest derivatives. These cells fall under the larger category of ectoderm, one of the three germ layers, along with mesoderm and endoderm. WebIn mice, germ layer differentiation is controlled by two transcription factors: Sox2 and Oct4 proteins. These transcription factors cause the pluripotent mouse embryonic stem cells to select a germ layer fate. Sox2 promotes ectodermal differentiation, while Oct4 promotes mesendodermal differentiation. Each gene inhibits what the other promotes.
