Action of the Wingless, Hedgehog, and Notch signaling pathways on midline precursor identity. At stages 8–9, sim expression in the midline cells commits all midline cells to an MP4 neural fate (blue). At stages 9–10, Wg activates slp1/2 in the anterior midline compartment, and commits those cells to an MP1 fate (red). At stage 10, Hh activates gsb/gsb-n, and commits a group of cells to an MP3 fate (green). At stage 11, Notch signaling selects cells to become neural precursors and glia (AMG and PMG); the darker colors indicate the formation of neural precursors.
