Fig. 7 Model for Notch signaling among midline precursor cells. During gastrulation, Notch activation among ntl+ midline precursor cells (MPCs) inhibits notochord and promotes hypochord development. Meanwhile, Nodal signaling specifies floor plate progenitors. Later, Notch is required for the proliferation of floor plate progenitor cells.
