Fig. 7. Absence of expression of olfactory GPCRs in zebrafish taste buds.

Fig. 7

In situ hybridization screening was carried out to examine the expression of GPCRs in taste buds (A–D) that are known as chemoreceptors expressed in olfactory sensory neurons in zebrafish and/or mammals. Mixed probes for OR111-1, OR111-2, OR111-3, OR111-5, OR111-7, and OR111-10 (A and E); mixed probes for OlfCc1, OlfCd2, and OlfCd3 (previously known as VR5.3, VR3.13b, VR3.13a, respectively) (Sato et al., 2005) (B and F); probe for zfTaar9 (C and G); and mixed probes for zfV1R1 and zfV1R2 (D and H) were used. No GPCR species were expressed in taste buds (A–D), but all probes used yielded strong signals in olfactory epithelium in zebrafish (E–H). n=1, number of sections ≥5 for each examination. Scale bar: 50 μm.
