Summary of FGF-dependent patterning in the mid-gastrula neural plate. FGF signaling at the 112-cell stages leads to asymmetric division of the row III/row IV precursors. Activated Ets1/2 and Elk1/3/4 lead indirectly to repression of Six3/6 in row III and expression of Myt1L in row I and medial row III. These Myt1L+ cells contribute to ependymal cells of the tail nerve cord (TNC) and sensory vesicle (SV). Ets/Pnt2 mediates expression of Tyrp1a and ultimately promotes pigment cell formation in the lateral a9.49 lineage of row III.
