(AR) Immunostaining in lumbar spinal cord sections from adult CGRPα-DTR+/− mice. (A–L) hDTR marks CGRPα-expressing afferents. (M,P) PKCβII (red), (N,Q) PKCγ (red) and (O,R) CGRPα-GFP (green) mark populations of intrinsic dorsal spinal neurons. (M, N, P, Q) NeuN (blue). (O,R) IB4 (blue). Images were acquired by confocal microscopy. Scale bar in (L) is 100 μm and (Q,R) is 50 μm. All tissue collected 7 days after second saline/DTX injection. Images are representative of n=3 male mice per condition.
