In most vertebrates, the notochord is eventually replaced by ossified vertebrae, but it …
WebExpert Answer. Ans :- The signaling molec …. What signaling molecule is secreted by the notochord to promote the differentiation of specific neurons in the neural tube? ОВМР TGF-beta OFGF Shh. WebIn amphibians, three signaling molecules—noggin, follistatin, and chordin—given off by the notochord are the inductive agents. It was first thought that these molecules directly stimulate uncommitted cells of the dorsal ectoderm to form neural tissue, but subsequent research on amphibians has shown that these inductors act by blocking the ...

WebIn vertebrates, endocrine glands are specialized organs that secrete hormones into the endocrine signaling system. Hormone secretion occurs in response to specific biochemical signals and is often subject to negative feedback regulation. For instance, high blood sugar (serum glucose concentration) promotes insulin synthesis. snatch sauceWebFeb 15, 2024 · Secreting signaling molecules (namely hedgehog proteins, such as sonic hedgehog (Shh)) to promote the development of the surrounding tissue and 2.
