Summary of Ectoderm
The ectodermal germ layer gives rise to tissues that are exposed to the external environment. High levels of bone morphogenetic protein stimulate surface ectoderm to form the epidermis, while an inhibition of bone morphogenetic protein and upregulation of fibroblast growth factor allows the notochord and prechordal mesoderm to induce the formation of the neural plate from overlying ectoderm. Neural crest cells dissociate from neuroectoderm at this time and migrate to underlying mesoderm, where they go on to form other structures throughout the body.
