WebMar 7, 2014 · FGF signaling in notochord promotes expression of a notochord-specific transcription factor, Brachyury (Bra), which is essential for notochord differentiation. Knockdown or mis-expression of Bra indicates that Bra is responsible for regulation of the number of cell division rounds, suggesting that Bra activates a putative mechanism to … WebMay 26, 2006 · Brachyury encodes a T-box transcription factor that regulates a variety of target genes controlling the cell shape changes and intercalary movements accompanying notochord differentiation ( 23 ). The anterior 32 notochord cells arise from the A7.3 and A7.7 blastomeres at the 64-cell stage.
WebThe ectoderm that lies immediately above the notochord is called the neuroectoderm, and gives rise to the entire nervous system. In addition to specifying the basic topography of the embryo and determining the position of the nervous system, the notochord is required for subsequent neural differentiation (see Figure 22.1).
