Notochord induction mechanism
WebApr 6, 2024 · The induction of reporter activity in our transgenic line fits well with the knowledge that the drug acts through the Nrf2 pathway by unknown mechanisms . To verify whether any loss of gene function could impact the Nrf2 pathway activity, we tested the transgenic line in a previously characterized glucocerebrosidase morphant zebrafish … WebJan 8, 2002 · In the embryonic chick, the induction of floor plate cells depends on signals from the notochord [1]. Expression of the secreted signaling molecule Sonic hedgehog (Shh) in the notochord is required for its ability to induce floor plate cells. Function-blocking antibodies directed against Shh prevent the notochord from inducing the floor plate [2].

WebImmediately beneath the neural plate is a rod-shaped mesodermal structure called the notochord. The notochord signals the neural plate cells to fold over to form a tube called the neural tube, as illustrated below. WebThe notochord is a long, rodlike structure that develops dorsal to the gut and ventral to the neural tube. The notochord is composed primarily of a core of glycoproteins, encased in a sheath of collagen fibers wound into two …
