(A) In situ hybridization revealed that three TAS1Rs, TAS2R13, PKD1L3, GNAT3, GNA14, and PLCB2 were robustly expressed in subsets of the TRCs in the CvP. These genes, except for GNA14, were also expressed in subsets of the TRCs in the FuP. n≥2 (numbers of sections ≥4) for TAS1R1, TAS1R2, TAS1R3, PKD1L3, GNAT3, and TAS2R13 in CvP, n = 1 (numbers of sections ≥2) for GNA14 and PLCB2 in CvP, n≥2 (numbers of sections ≥20) for TAS1R1, TAS1R2, TAS1R3, PKD1L3, and GNA14 in FuP, n = 1 (numbers of sections ≥10) for GNAT3, PLCB2, and TAS2R13 in FuP. (B) The TAS2Rs located on chromosome 11 (TAS2R9 and TAS2R12-25) appeared to be robustly expressed in subsets of TRCs, whereas only weak signals were observed for the TAS2Rs located on chromosomes 3 (TAS2R1-8 and TAS2R10-11) and 6 (TAS2R26). Tas2Rs are arranged according to the locations on the chromosomes (see Figure S1). n = 2 (numbers of sections ≥4) for TAS2R1-8, 10-11, 21, 23, and 26, n = 1 (numbers of sections ≥2) for TAS2R9, 12, 14-20, 22, and 24-25. Scale bars: 50 µm.
