text: Figure 4. Spared nerve injury induces a loss of Trpm81 and CGRP1 but not myelinated DRG neurons. (A) Schematic of experimental approach. (B–D) FastBlue 
  labelling and Trpm8-tdTom (B), Calca-YFP (C), or Thy1-CFP expression (D) 28 days after SNItrans in the L4 DRG, contralateral (top) or ipsilateral (bottom) to injury. 
  Images are projections of optical sections at 3-mm intervals through the entirety of 30-mm-thick tissue sections. Scale bars 5 100 mm. (E–G) Quantification of the 
  proportion of FB-labelled neurons also expressing Trpm8-tdTom (E), Calca-YFP (F), or Thy1-CFP (G) in L4 DRG contralateral or ipsilateral to SNItrans. Paired t tests; 
  Trpm8-tdTom: t2 5 5.31, P 5 0.034, n 5 3 mice; Calca-YFP: t3 5 4.12, P 5 0.026, n 5 4 mice; Thy1-CFP: t3 5 4.42, P 5 0.022, n 5 4 mice.*P , 0.05. CFP, cyan 
  fluorescent protein; CGRP, calcitonin gene-related peptide; DRG, dorsal root ganglion; FB, FastBlue.
