GFP-labeled fibers are observed along the nerve path of the reflex arc. a VGluT1-positive proprioceptive fibers (the peripheral branch of proprioceptor DRG neurons) in muscle spindles of the IMF were also positive for GFP in Atf3:BAC Tg mice after RCS. b GFP-positive fibers innervated the neuromuscular junctions in IMF of Atf3:BAC Tg mice after RCS. α-Bungarotoxin (α-BTX) labels ACh receptors, and class III beta-tubulin (Tuj1) shows axon terminals. Note that GFP-positive axons also innervated ACh receptors in the IMF. Scale bars, 20 μm
