1% WGA-488 or WGA-568 was injected in tongues of mice bilaterally and 3 days later, TG tissues were harvested for immunostaining. Transgenic reporter mouse lines were used to determine the types of sensory neuron innervating mouse tongue. a. Number of Neurons expressing the marker and co-localizing with WGA were counted from 2–3 animals per group. Data are presented as mean +/- SEM of percentage of neurons expressing each marker. b. Each TG tissue sections from each retrogradely labeled transgenic mouse was stained with antibodies specific for either TRPV1, CGRP or Calbindin. Data are presented as WGA-labeled neurons expressing both markers. c. Representative immunostaining of TrkC-TDT, WGA and TRPV1, CGRP or Calbindin. d. Representative immunostaining of Parv-TDT, WGA and TRPV1, CGRP or Calbindin.E. Representative immunostaining of 5HT3A-GFP, WGA and TRPV1, CGRP or Calbindin. Arrows indicate colocalization of WGA and reporter gene.
