Histological characterization of L6-S1 dorsal root ganglion (DRG) neurons that project to the bladder from SNS-Arch mice. (A,B & C) Immunohistochemical analysis of tissue from SNS-Arch mice confirms GFP reporter expression in L6-S1 DRGs. Labeling of bladder-innervating DRG neurons was achieved via bladder injections of the retrograde neuronal tracer cholera toxin B. Co-labeling of GFP and CTB-555 with the neuronal markers calcitonin gene related peptide (CGRP), neurofilament 200 (NF200) and isolectin B4 (IB4) reveal a mixed population of sensory neurons that innervate the mouse bladder; scale bar 100 μm (n = 2). (D) Whole mount staining of the bladder wall shows sensory neurons expressing GFP innervate the bladder wall of SNS-Arch mice and co-label with β3-tubulin; scale bar 100 μm.
