Notochord induction mechanism
WebJun 1, 2002 · Therefore, molecular events that take place at the 16-cell or 32-cell stages and to eventually activate Brachyury expression are key to understanding the mechanisms of notochord induction. In a previous study, we characterized Cs-FGF4/6/9 cDNA as a possible notochord inducer, and showed that the corresponding gene is expressed in the … 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.
