Co-expression of Lmo4 and other muscle sensory neuron markers in lumbosacral DRG proprioceptive sensory neurons (LS1-4) during development

Stage	% of Pea3-positive cells	% of ER81-positive cells	% of trkC-positive cells
27	86% (132/154)	NA^{^†}	NA^{^‡}
35	71% (63/159)	65% (171/317)	83% (235/280)

Stage	% of Pea3-positive cells	% of ER81-positive cells	% of trkC-positive cells
27	86% (132/154)	NA^{^†}	NA^{^‡}
35	71% (63/159)	65% (171/317)	83% (235/280)

NA, not applicable.

^†

At stage 27, sensory neurons do not yet express ER81.

^‡

TrkC is expressed in both proprioceptive sensory neurons and trkA-positive cutaneous sensory neurons at stage 27; therefore, trkC is not an appropriate marker at this stage.
