Fig. 6. Comparison of Lmo4 (red in all panels) with the ETS gene Pea3 (green in A,C,E) and ER81 (green in D,F) in sensory and motoneurons. (A) At stage 27, most Pea3-positive (green) sensory neurons are Lmo4 positive (yellow cells), but a small subset (arrows) is Lmo4 negative. (B) By stage 35, when trkC expression (green) serves as a good marker for muscle proprioceptive sensory neurons, a small proportion of trkC-positive cells remain Lmo4 negative. At this stage, Lmo4 is expressed in many, but not all, Pea3-positive (C) and ER81-positive(D) sensory neurons. In the LS2 spinal cord, Lmo4 is expressed in many, but not all, Pea3-positive (E) and ER81-positive (F) LMC motoneurons. See also Table 2. Scale bars: 25 µm in A; 100 µm in B-F.
