A CGRP-positive nerve fibers are present but do not contact TrpM5-+ cells. B SUS-1 labels SCs in the MOE but not TrpM5-+ cells. C GFP-+ TrpM5a cells show villin immunoreactivity in their microvilli and in their cell membranes. D Microvilli and the cell membrane of a GFP-+ TrpM5b cell labeled with villin antisera. E GFP-+ TrpM5a type cells show espin immunoreactivity in their microvilli. In addition to TrpM5-GFP-+ cells some non-TrpM5 cells show espin label (arrow). Some ORNs are slightly GFP-+ but are espin-negative. F Microvilli of GFP-+ TrpM5b cells labeled with espin antisera.
