FIG. 1. — Expression of taste cell markers and VIP in circumvallate papillae of wild-type (WT) and VIP knockout (KO) mice. Type II cell marker (PLCβ2) (A and B), type III cell marker (NCAM) (C and D), and type IV cell marker (Shh) (E and F) are expressed in taste cells of both wild-type and VIP knockout mice. Scale bars, 20 μm. Blue is TO-PRO-3 nuclear stain. G and H: VIP (red) is expressed in a subset of taste cells of wild-type mice. I and J: VIP is not expressed within the VIP knockout mouse taste bud. Scale bars, 20 μm. Sections are representative of three mice. (A high-quality digital representation of this figure is available in the online issue.)
