Nmr1 and Nmr2 are detected in a few Zfh-1-expressing motor neurons.
(A–L) Wild-type stage 15 embryos stained for Zfh-1 (red) and Nmr2 (green) or Nmr1 (green). (A–C) In the ventral region of the CNS, Nmr2-positive and Zfh-1-positive neurons are co-expressed in approximately 2–3 neurons in the medial Nmr2-expressing cluster per hemisegment (merge, arrows). (D–F) Dorsally in the CNS, a single lateral neuron co-expresses Nmr2 and Zfh-1 per hemisegment (merge, arrows). (G–I) In the ventral region of the CNS, no cells co-express Nmr1 (green) and Zfh-1 (red). (J–L) In the dorsal region of the CNS, one lateral neuron weakly co-expresses Nmr1 and Zfh-1 per hemisegment (merge, arrows).
