In contrast, precocious ETS signaling leads to severe defects in the establishment of DRG neuronal projections accompanied by inappropriate gene expression changes (C; upregulation of CR (red) and downregulation of TrkC [grey]).\n(E) Precocious ETS signaling (red) during progressive specification of proprioceptive sensory neurons leads to aberrant neuronal differentiation (red dashed line). In contrast, the isochronic, target-induced (green; peripheral signal) onset of ETS transcription factor signaling (black) induces appropriate terminal neuronal differentiation (blue).","divisions":[{"label":"label","span":{"begin":0,"end":8}},{"label":"title","span":{"begin":10,"end":133}},{"label":"p","span":{"begin":134,"end":364}},{"label":"p","span":{"begin":365,"end":833}}],"tracks":[]}
