B , Immunofluorescence labeling of adult GG from Th -CreER; Rosa RFP mice using antibodies to <t>TUJ1</t> (green), PHOX2B (blue), and RFP (magenta) identifies a population of PHOX2B+ neurons that also express RFP ( Th ). C , Immunofluorescence labeling of Th -WT; Rosa RFP mice, as in B , confirms the specificity of the RFP immunoreactions. Immunofluorescence labeling of nodose/petrosal/jugular ganglion complexes from Th -CreER; Rosa RFP mice using the same antibodies in B demonstrated the presence of Th +/PHOX2B+ oral sensory neurons in petrosal ganglia as well, shown in Extended Data . D , Serial sections of GG evaluated with both methods were counted and quantified to determine what percentage of Phox2b + neurons coexpressed Th . Only high Th -expressing neurons are graphed in D for the in situ hybridization. The p value is p = 0.0027. E , Serial sections of GG were quantified to determine the number of Th -expressing neurons that did not express Phox2b . Error bars represent mean ± SEM, and n = 3–4 mice were analyzed by each method. The p value is p = 0.2797. Scale bar in A is 100 μm, and the scale bar in B is 100 μm and applies to all panels in C . ** denotes p < 0.01, and ns is not statistically significant.

    Analysis of NEUROG1-deficient ears indicates that the nonsensory defects are not caused secondarily from reductions in the otic ganglion. (A-C) Low-power midmodiolar sections from control (A), Neurog1−/− (B) and E8.5 Sox2-deleted cochleae (C). The nonsensory phenotype was more severe in the absence of E8.5 SOX2 than of NEUROG1, and some neuronal formation still occurred [arrows mark neuronal expression <t>(TUJ1;</t> white) in C,F,I]. (D-K) Higher magnification views of the boxed regions in A-C highlight that sensory formation occurred fairly normally in the Neurog1-deficient mutant. (L-T) Examples of cross-sections through each vestibular organ in control (L-O), Neurog1−/− mutant (P-S) and E8.5 SOX2-deleted inner ears (T). The vestibule forms relatively normally in Neurog1-deficient mutants, with the exception of a smaller saccule devoid of sensory markers (arrow, P). By contrast, the only vestibular structure seen in E8.5 SOX2-deficient inner ears was an underdeveloped saccule (T). Scale bars: 50 µm.

    Fibers from Th -expressing neurons preferentially innervate taste buds in the soft palate and circumvallate papillae. A , Fungiform (top two rows), circumvallate (third row), anterior foliate (fourth row), soft palate (fifth row), and nasoincisor duct (sixth row) taste buds were immunolabeled with antibodies to K8 (green), TUJ1 (blue), and RFP (magenta). RFP+ fibers innervated half of fungiform, anterior foliate and nasoincisor duct taste buds, and innervated all circumvallate and soft palate taste buds. For fungiform taste buds, images are displayed in two separate rows depicting an example of innervated (top) and noninnervated (second row) taste buds. B , Chorda tympani and greater superficial petrosal (GSP) nerves were immunofluorescently labeled with antibodies to TUJ1 (green) and RFP (magenta), showing the presence of RFP+ fibers projecting through each nerve. Three mice were imaged in these experiments. Scale bars in A are 20 μm, and the scale bar in the top row of fungiform taste bud images applies to the second row as well. The scale bar in B is 100 μm and applies to all panels in B .

    Fibers from Th + oral sensory neurons enter the rostral portion of the NTS. A , Th -CreER; Rosa RFP mice were administered tamoxifen and allowed to recover for three weeks before the brainstem was isolated. Coronal serial sections through the NTS were immunolabeled with antibodies to TUJ1 (green) and RFP (magenta). The white arrows indicate the solitary tract that is lateral to the NTS (indicated with yellow arrows). Successive sections are displayed progressing from top row to bottom row so that the progression of the solitary tract to the NTS can be appreciated. Scale bar: 100 μm. B , Th -CreER; Phox2b -FLPO; RC::FLTG mice were administered tamoxifen and allowed to recover for three weeks. Coronal serial sections were immunolabeled with antibodies to TUJ1 (blue) and eGFP (green). The white arrows indicate the solitary tract and yellow arrows denote the NTS. The bottom row is a higher power image of the row above it. The scale bars are 100 μm. The scale bar in the first row in A applies to all panels in A , and the scale bar in B applies to all panels in B . Four independent mice of each genotype were analyzed in A and B .

    Analysis of NEUROG1-deficient ears indicates that the nonsensory defects are not caused secondarily from reductions in the otic ganglion. (A-C) Low-power midmodiolar sections from control (A), Neurog1−/− (B) and E8.5 Sox2-deleted cochleae (C). The nonsensory phenotype was more severe in the absence of E8.5 SOX2 than of NEUROG1, and some neuronal formation still occurred [arrows mark neuronal expression (TUJ1; white) in C,F,I]. (D-K) Higher magnification views of the boxed regions in A-C highlight that sensory formation occurred fairly normally in the Neurog1-deficient mutant. (L-T) Examples of cross-sections through each vestibular organ in control (L-O), Neurog1−/− mutant (P-S) and E8.5 SOX2-deleted inner ears (T). The vestibule forms relatively normally in Neurog1-deficient mutants, with the exception of a smaller saccule devoid of sensory markers (arrow, P). By contrast, the only vestibular structure seen in E8.5 SOX2-deficient inner ears was an underdeveloped saccule (T). Scale bars: 50 µm.
