Proprioceptors are preserved in wi/wi mutant mice. A, Expression of Rx3 and Whrn in DRG of adult (>6 months) wild-type and wi/wi mutant mice. B, Numbers of Rx3+ neurons in adult L2 DRG in wild-type and wi/wi mutants are similar (p = 0.389, t test). C, pSN axon collaterals as visualized by expression of Pv in p15 wild-type and wi/wi mutant mice. i′, i″, ii′, ii″, Enlargements of ventral motor neuron areas. D, vGluT1+ synaptic terminals oppose Shank1a postsynaptic densities in p15 wild-type and wi/wi mutant mice. E, vGluT1+ MS and GTO sensory endings in p10 gluteus muscle in wild-type and wi/wi mutant mice. F, Number of MS sensory endings (SEs) is similar in wild-type and wi/wi mutant Soleus (Sol) muscle (p = 0.428, t test). G, Number of GTO SEs is similar in wild-type and wi/wi mutant Sol muscles (p = 0.471, t test). Number of DRG (B) or muscles (F,G) analyzed is indicated in parentheses. Error bars indicate SEM. n.s., Not significant. E, Schematic insets, Plane of section. Scale bars: A, E, 20 μm; D, 1 μm; C, 50 μm.
