Distribution of retrogradely labeled DRG neurons following injection of DiI into the mouse distal colon. (A) Following DiI injections made 9–15 mm from the anal sphincter (measured from unstretched colorectum preparations), the distribution of retrogradely labeled DRG neurons were identified. The majority of labeled neurons were identified in the lumbosacral region of spinal cord. Primary labeling was identifiedat levels of L6 and S1. (B) Fluorescence micrograph showing labeledneurons at L6.
